Since the tone stack is pre-distortion you need to do your post distortion tone shaping using the EQ. ", "The circuit is slightly different than the original 5F1. ", (to emulate Pull Shift on the Bass) "Put a Tilt EQ before the amp block with a frequency of 320 Hz and a gain of -3 dB. You are using an out of date browser. So its no surprise that while growing up there David Friedman was inspired by Detroits heady music scene and its legacy. The Bright channel model is selected by turning on the Bright switch. This means the amps are biased somewhat cold to begin with and shift to very cold as soon as overdriven. The matching cabs are 16 ohms but if you use an 8-ohm cab you'll get 30% less feedback. FWIW, this is a terrible loop design but "it's a Dumble" so it's all part of the mystique. That amp was one of the primary amps used in the G2 modeling development. There is no right or wrong. Dave Friedman is an amp-whisperer to the stars. Totally different model. David Friedman, the birth name of David Benioff (born 1970), American screenwriter Dafydd ab Hugh (David Friedman, born 1960), science fiction/fantasy writer; political weblogger David D. Friedman (born 1945), anarcho-capitalist writer, economist, and medieval reenactor David Friedman (poet), American poet Law [ edit] It's really just a bunch of EQ presets and it interpolates between them as you increase the value. Check Price The model is based on that. Guitar tube amp design was nascent in the 60s and 70s and designers didn't fully understand the impact of overdriving tubes. On PCB amps I usually only have issues with the hookup wires but never the board itself unless a design issue. That raspiness helps it cut through in a mix. This reduces the signal level substantially and lessens the amount of blocking distortion.". The treble boosting amplifies the upper frequencies of this noise burst which is what you hear. This occurs because the Legacy has so much negative feedback (12 dB, which is the highest of any amp I've ever modeled). ", "If you want that Recto crunch but not so flubby and fizzy try the SOLO models. This stage clips, because of all the local negative feedback, quite hard. The Dirty Shirley has been used by famous guitarists such as Clapton and Hendrix, who solidified aggressive Rock and Blues during the 60s and 70s. This is the treble Pull Shift on the IIC+ and the Pull Fat on the Mark IV. The JJ-Junior still gives you the same 2-channel, EL-powered tone that has carved out a legendary place in rock. It essentially does the same thing as the Bright knob though less precise. Some of the add-ons on this site are powered by. ", "Yeah, Buttery was a legacy model from the first Axe-Fx.". ", "The Badger doesn't have a Bright switch. ", "One of the first mods people make to real 'Plexi' Marshalls is to "clip the bright cap". Featuring beautiful black Tolex, grille cloth, and Baltic Birch just like the original JJ-100, youre basically getting everything you would with the larger, more-expensive amp but in a more condensed and affordable way. Probably because it's so nasty with it in. ", "Chris Quigley's 6505 was the reference amp. Just to be sure I just compared the Deluxe Verb model with the reference amp and it's correct. This gives clear bass response without getting flubby. You may want to turn the Bright Switch off as well. The bright cap in Marshalls can be very bright and harsh. This results in a negative feedback value of 3. No they aren't. The BE-100 offers the famous plexi sound of superstars like the Foo Fighters, Alice in Chains, Bon Jovi, and The Cult. It's not overly different in character to the modern setting, less gain and less low end essentially. Our world famous amplifiers. You lose the cathode follower compression and the high source resistance of the plate alters the tone stack frequency response. The real world speakers of choice are EVM12L in a 1x12 rear ported and 2x12 with Celestion Classic Lead 80's. The newer amp is brighter and tighter. ", "There isn't any way to run the virtual power tubes in triode mode but you can change the Power Tube Type to "300B" which is a triode. ", "The feedback circuit is responsible for the behavior of the Presence and Depth controls. You can see this is you run Tone Stack Calculator for the Marshall tone stack and increase the source resistance. On a recent trip home, the Friedman crew shot some footage, wed like to share with you. In terms of amps, his early years with the band saw him use a Mesa Boogie Studio Preamp as his main stage amp though lately he has been known to use Laney L50H Lionhart Amp heads and. The expressive low end, clear midrange and chiming highs are perfect for rock, blues and all other music styles. The foot controller and bias monitor are two of the wonderful features of the actual amp, but are both moot in the modelunless Cliff wants to model the effects of real world mains power fluctuations from place to place, but the 'green zone' of the bias monitor is 62-65% plate idle dissipation power and it measures and compensates for plate voltage and screen power , which means the real amp runs best at a slightly cooler bias. These amps were distinctive for their F.M. This results in the amp sounding more open and smoother. ", "When modding Marshalls for higher gain sometimes the modder will decrease the input frequency response to reduce noise and fizziness. This ruggedly built cab has a punchy closed-back sound with huge low end thanks to the ported design. The Recto1 models are based on our Rev. Very spitty as one would expect given the lack of a grid stopper resistor between the last triode stage and the PI. If you continue to use this site we will assume that you are happy with it. If you look at the schematics on the web the Maz-38 is shared cathode. This makes the MV even more sensitive than usual since theres another interaction going on. In this case mid means the stack is between the buffer and gain stage. Clean to "Cinammon Girl" with the volume knob. The other models are based on our original "Marsha". Takes the guesswork out. It has a boatload of gain and sounds more like a Plexi than a Fender. You don't hear it through a guitar cab typically but using close-mic'd IRs it's more noticeable. David Friedman was born and raised in Detroit, Michigan. I also adjusted the Preamp Bias so it wasn't so off-center. ", (about the Drive knob) "Our reference amp has a linear taper pot so the behavior is very abrupt. ", ("Cygnus" amp modeling) "I've added a non-jumped version of the 5E3 with both volume knobs. I had to increase the Mid control on the model to about 5 to match the amp which indicates the mid pot on the amp was greater than spec. ", "They had no Master Volumes so people rarely got the Drive past 3.00 since it would melt your face. While the real amp has a six-position Tone switch, the model has a continuously variable tone control. Since V1A and V1B run clean (linear) Input Trim will accomplish the same thing as increasing the trimmer into the drive stages. The JB100 model is basically an OD2 with the entire OD circuit on the board with predefined filters made up of quality components without adjustment through fragile trimmers. These boards are usually punched and are cheap. JavaScript is disabled. I have to turn the presence way down. ", (Cygnus) "Carvin Legacy 100. The Preamp Tube Type parameter only affects the tubes after the input buffer. ", "Mine doesn't have the depth mod but I used the values from the schematic I have and I believe the schematic is correct. ", "Based on a Blankenship Leeds which is a boutique version of an 18W Marshall. IOW all over the map. ", "Fat and Presence shift work as the real amp. Fortunately you can reduce this by reducing the LF Resonance on the Spkr tab which is something you can't do with the real amp without trying different speakers or cabinet. ", "The Brit 800 #34 does a better Slash than the AFS100 IMO. There were two versions of the 2204. Or you can use a high-shelf filter which is a little more subtle. This is accomplished typically by putting a capacitor in parallel with the plate resistor(s) which rolls off around a few kHz. Commensurate with (1) I found myself turning the midrange down as well as the bass and turning the treble up. Like most boutique amp makers Friedman's designs have evolved over time with changes to the circuit. ", "Our reference amp is the same model Mark Knopfler used on the Dire Straits eponymous album. It's not as accurate but some people really liked it so we kept it and created new models for the Ares/Cygnus platform. The model matches that particular amp very well. ", "This model is my interpretation of the ideal modern metal tone. ", "That amp exhibits a lot of blocking distortion (in the phase inverter) due to its design. The Pull Deep switch engages a large cathode cap on the final triode stage. ", "The model was matched to Dweezil's amp. I had a buddy who was clowning on me for trading into that Bogner bc the amp I had before it was a handwired fender clone that I honestly cant remember the builder or model. ", "The design is weird as the negative feedback is taken off the speaker jack. With everything at noon the tone stack looks like a highshelf with a good amount of high frequency cut. Experts state that Friedman amps are more affordable and slightly chewy Marshalls. As it is virtually unplayable like this, the model uses a somewhat reduced level of grid conduction to lower the amount of blocking distortion and make the amp more playable at high Drive settings. I have a fantastic 4x12 with 2 old greenbacks and two old v30s that is the best cab I've played the real amp through. The treble cap is still in the circuit path. This was/is done to compensate for the lack of a buffer for the fx loop. If you want the amp to feedback effortlessly on a note, raise the overdrive setting higher combined with the gain, provided you have sufficient volume coming out your speakers to hit your guitar pickups in a reinforcing loop, it will do it! ", "With the presence control at noon it's roughly neutral. They are nasty, aggressive things that you have to crank the MV. ", "The Rocket has a different preamp (than the Express) with the tone stack before the PI. Enter your email address to be first to hear about our new products and special offers. turn the Mid, Treble and Presence way up; turn Norm Drive and Bass down a bit. Dave has been building, modding and repairing amplifiers for many of the worlds biggest stars for the past 25 years. For the money, you could opt for amps with many more features but the simplicity of the Buxom Betty is perhaps the best thing about it. ", "The tone stack on a Boogie is pre-distortion. ", "JP2C doesn't have a depth knob. A newcomer to the scene of boutique-style, small-sized amps from Friedman is the Runt-50. Old Plexis didn't do this because they had good transformers. AC-30's have kind of crappy OTs. There are even some amps that have circuits to intentionally generate crossover distortion. You have to really crank the MV though (just like the real amp). If you turn off Bright you're effectively clipping the bright cap. Combined with the smallish output transformer there is a loss of phase margin at low frequencies which causes the power amp to become unstable. ", (mimic Pull Gain on clean channel) "Just set the Tonestack Type to Hook Clean 2. ", "The real amp is known for it's tremolo so that's why we used the bias trem on the preset. Theyre loved by many professional musicians, and the brands website has a page dedicated to famous artists who use Friedman amps. ", "Another caveat when comparing amps: many times the knobs aren't "centered". This is a topic that comes up frequently on this board with lots of strong opinions in tow. PBGas Well-known member May 18, 2021 #5 ", ("Cygnus" amp modeling) "The Bassman was reworked using an original 59 Bassman 5F6-A as a reference. On a Mark V the tapers are different so you get more midrange and treble for the same settings. I have several but this particular one has 6CA7s and 82K grid resistors(!). ", "Buttery is a virtual amp model that was created by ear. More dynamic and open than a Plexi, but with more gain. ", "AC30's have no negative feedback on the power amp. The frequency and Q behavior is spot-on. As no two Dumbles are identical it stands to reason that one person's interpretation of the ideal Dumble voicing may not agree with another's. The Tucana falls in to this category. JavaScript is disabled. This results in a lot of negative feedback at high frequencies which makes the sound dark. In the first Tonetalk episodes, his statements weren't so direct and he called Profilers and Axe-FX good tools for certain things. In most cases a reverse log taper would be the ideal taper. ", (blackface) "Not a huge change with the Silverfaced versions. In the actual amp the Treble control is re-purposed as a Negative Feedback control. It biases the stage much too cold for my tastes. Way more than most people would need for recording or live playing. ", "The Buttery model was REPLACED by a Budda Twinmaster model. The preamp is virtually identical to a Twin Reverb but 6V6s break up earlier than 6L6s. With Pull Deep off there is actually a shelving response into the power amp (bass is reduced). typical 50W Marshall has a primary impedance of about 3200 ohms. ", (Def Leppard) "The amp model you are looking for is "JMPre-1 OD1". Bias trem works by modulating the power tube grid bias. These were my settings for a killer high-gain tone: Model: USA IIC+ / Input Drive: 8.1 / Overdrive: 9-10 / Bass: 1.0 / Midrange: 1.8 / Treble: 8.9 / Presence: 4.5 / MV: 4.0 / Level: -20 dB / Bright Switch ON / 80 Hz: 4.8 / 240 Hz: 2.6 / 750 Hz: -4.5 / 2200: -0.2 / 6600: 0. We earn a commission if you make a purchase, at no additional cost to you. Each Friedman amplifier is built in the U.S.A. to Dave's exacting . Put all knobs at noon if you want authentic. There are even some amps that have circuits to intentionally generate crossover distortion. The location in the circuit board is empty and the solder joints do not appear to have been disturbed. Well-known member May 18, 2021 #4 Top Shelf all the way. Adjust LF Res, Freq and Q to get desired response. Even just a short cable. Most amps use an audio taper pot. The HRM case the neutral tone stack is replaced by a Marshall tone stack. To derive from Classic American Clean to Classic British Crunch all you need to do is turn up the volume knob its that simple and the results are incredible. When you consider 3 toggles hanging freely 'hand wired' vs 3 toggles anchored at the back to this tank of a PCB the PCB approach is more robust. I found the 12L emulation did a pretty good job. ", "The power amp in a Rockerverb has very little negative feedback so it will boost the highs more than most power amps. As such there's a lot of bass going into the power amp. Looks like it was that way from the factory. So if you use a 16-ohm speaker you get more feedback (and much more bass) than if you use an 8-ohm speaker. Runt (I don't even want to imagine what he's thinking of) Seriously guys. ", (firmware Ares 14.00) "The Tube Pre model has been changed so that the power amp is off by default. You can try increasing the Variac. The transformer resonance is adjustable but the parameter isn't exposed to the user. ", "The "Treble" knob on the Chietain model is actually Preamp Presence. ", "OD2 switches in a cathode bypass cap which increases the gain of that stage. Another thing to try is to increase the Grid Clipping value which will add a little headroom. The is probably the reason Leo Fender switched to fixed bias amps with negative feedback. Jodie fell in love with the guitar at a young age, but has hit a lot of bumps in the road with her journey. Fixed bias is just that, the bias point is fixed so the amp doesn't shift into Class B operation when overdriven (not as much anyways, depends on the bias circuit, grid stoppers, etc.). The default Depth value when you select the Euro Uber model is equivalent to the amp's fixed depth circuit. There are two gain stages. ", "The Badgers were MIMIC'd with power scaling at full. Most people assume knobs should be set somewhere around noon. ", "A Princeton Reverb has an extra gain stage due to the reverb recovery. This is the amp used on Dire Straits eponymous album. Song Lyrics David Ingles Music. ", "Yeah, it's a cool little amp. ", "I always used the Fat switch with the real amp." The unique thing about a Dual Recto tone stack is that the Presence control is part of the tone stack. ", "They call HRM "Hot Rubber Monkey" but what it really means is "Hot Rod Marshall"." The models assume the Overdrive Volume is at maximum. ", "Based on a 1981 JMP 50W Master Volume head. EDIT** You know what, I'm not ruling out the Fryette Power Station just yet, that thing is a two 6L6 50 watt power amp also, man the specs look amazing. If you like the base Dumble sound but want a little more gain without the fuzziness of a Fuchs try the Carol-Ann models. The HRM Dumbles have a fixed Marshall tone stack at the output of the lead channel. When you run a pentode (or beam tetrode) in triode mode you connect the screen to the anode which effectively defeats the screen. Customer Reviews. I had a live show I did with the Bogner recorded and its one of my favorite shows (for tone) I have had recorded. The model models the amp with the bright switch on. - Dave Friedman - Friedman Amplification CEO. Some had 100K off the 8-ohm tap and some even had 47K off the 16-ohm tap! ", "Rectos don't have a Depth control and even if they did it wouldn't do anything in Modern Red mode since that mode has no negative feedback. ", "All passive tone controls interact and all the Axe-Fx tone stacks replicate this behavior. We did notice that this amp has less gain than the one used originally but the model is faithful to the amp. Neither will the Depth. ", "It's unique character comes from the PI. When it comes to finding the best Friedman amps it can be challenging to determine whether its worth looking at high-end Friedman Amps or if a lower-priced amp would be sufficient for you. Unlike the amp, however, you can actually adjust the tone controls and something will happen. ", "That's a "James" tone-stack. Now we can wait for the inevitable "When I turn the Bright Drive all the way down the Normal Drive doesn't do anything" comments. Just like the real amp you have to be careful with your volume control and how you approach the amp so that you keep it right on the edge of playability. Here are some tips: The old version of the model incorrectly referenced the Mark IV tone stack. ", "The Mid switch, sometimes labeled "Deep", shorts out the 390 pF cap in the tone stack (which is in series with a 2 nF cap). Single notes can form an almost perfect square wave which will sound like a synthesizer. Same transformers. I prefer hand wired. Fryette Power Station would be nice but I'm not wanting to drop that much. ", Archean: Lead channel with Bright switch OFF, Archean Bright: Lead channel with Bright switch ON, "You have to crank the MV on the real amp. He seems to understand the modern player is seeking quieter, more convenient options to the traditional 100W heads and wall of 4x12's, as much as he says he loves them. The model defaults to the bright cap in the circuit. Below we investigate the best Friedman Amps (in our opinion). With the iconic modded all-American character and old-school aesthetics, this is a pretty eye-catching amp that any traveling musician would feel proud to have on the road with them. Otherwise it's a shrill mess. True that the majority do not but this particular amp has quite a bit of NF. Was hearing a lot of ghost notes compared to the old algorithm (in the debug build I can select between algorithms with a hidden parameter) and figured that couldn't be right. ", "Most amps use a linear taper for the treble pot. However, many guitarists say that they never look back once theyve played with a Friedman amp. Personally I don't think the Dumble topology lends itself to that much gain but I didn't design the amp. Steve Stevens and Jerry Cantrell turn the bass way up too. ", BE C45: based on Mark Day's BE-100, C45 switch engaged, BE V1: based on Mark Day's BE-100, voice: right position (less mids), BE V2: based on Mark Day's BE-100, voice: left position (more mids), HBE 2018 C45: based on 2018 BE-100, HBE mode, C45 switch engaged, HBE V1: based on Mark Day's BE-100, HBE mode, voice: right position (less mids), HBE V2: based on Mark Day's BE-100, HBE mode, voice: left position (more mids), BE 2010: based on Friedman BE-100 from 2010 (probably the "Marsha" edition), BE C45: based on later BE-100, C45 switch engaged, BE V1: based on later BE-100, voice in left position, BE V1 Fat: based on later BE-100, voice in left position, FAT switch engaged, BE V2: based on later BE-100, voice in middle position (brightest), BE V3: based on later BE-100, voice in right position, HBE 2010: based on Friedman BE-100 from 2010 (probably the "Marsha" edition), HBE mode, HBE C45: based on later BE-100, C45 switch engaged, HBE V1: based on later BE-100, voice in left position, HBE V1 Fat: based on later BE-100, voice in left position, FAT switch engaged, HBE V2: based on later BE-100, voice in middle position (brightest), HBE V3: based on later BE-100, voice in right position, (before Cygnus) "The old model is an original, hand-built "Marsha". To simulate this increase the Negative Feedback. been wanting one for years, but I thought he wasn't making them any more. Usually a linear taper pot is used for the treble. "There's a treble cut on the tone stack and a some minor changes to the power amp and power supply but it's basically a ripoff. Depending on the tubes used the bias can run from average to cold. ", "They're simple amps with minimal tone shaping. For over a decade Dave Friedman's "BE" circuit has been hailed as the epitome of British tone.
