", "I have a really good SLO-100. One of Friedmans mainstays has been modifying amps to each players specific tonal palette, and to consult with other established amplifier companies to improve their own designs. ", "Mesa claims it's based on the IIC+ but it's different. Will it match an AC30 from a different era exactly? However, many guitarists say that they never look back once theyve played with a Friedman amp. There's nowhere I would ever be able to get the amp to the point of pushing the power tubes in to overdrive. Dave Friedman's extensive knowledge and pursuit of tonal superiority inspired him to develop his own series of production amplifiers under the name Friedman Amplification. This is the treble Pull Shift on the IIC+ and the Pull Fat on the Mark IV. ", Based on latest version of amp. True that the majority do not but this particular amp has quite a bit of NF. IMO it doesn't have enough feedback (100K off the 4-ohm tap). It's a Blackface Twin which breaks up easy compared to later Twins. ", "Note that the Orange Modern and Red Modern models have no negative feedback and therefore the Presence control is a Hi Cut control. Turn the Drive down. Contrast this with Class-AB where when one tube conducts the other goes into cutoff causing a net increase in supply current and concomitant supply sag. ", "You increase the LOW CUT FREQ to reduce the fuzziness on bass notes but then it won't sound like the real thing. Legend II is channel 3 from the Legacy 3. This cuts the bass, shifts the midrange and lowers the gain slightly. Friedmans amps guts I've seen are nicely made, but nothing to write home about. If anything it should be linear. ", "So-called Class-A amps (like the AC30) don't actually exhibit much power supply sag because, well, they're Class-A (or nearly). "The previous model wasn't based on any real amp. You can see this in the Axe-Fx II as your Triode Freq parameters. The cathode follower in an AC-30 doesn't even do all that much. The model is based on using the matching cab. The new BE-100 Deluxe, like its little brother the BE-50 Deluxe, takes this BE circuit to a whole new level, This new BE-OD Deluxe pedal employs the exact same circuit but adds another channel and dual midrange controls. Many of Rock's most iconic players labor over how to get 'that tone' they keep hearing in their head. ", "Pre, mid and post aren't absolute locations. ", "The bright cap value is normalized to a Drive pot of 1M. Dave Friedman is the man behind the signature tones of rock icons Eddie Van Halen, Steve Stevens and Jerry Cantrell. Every bit of information I've found says that people typically used the Pull Bright on the Volume knob. This causes lots of crossover distortion (papery buzz). Subtle is the only possibility with this configuration. Also a matching 4x12 cab. After a rigorous burn in process, Dave inspects, tubes, plays and signs the chassis of every amplifier before shipping. AB763, does not mean that the circuits are identical. Why they chose a log taper in the 5150 is a mystery. With a single-ended power amp with negative feedback the gain doesn't change much as you change the operating point, hence the tremolo effect is subtle. 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. At 9:00 on the Master the power amp is distorting (it's probably a linear taper pot for the ol' "Wow, this amp is loud bro!"). ", "It's still the "ear tuned" version. Both with the Lead 1 Red board. Too much IMO. Friedman amps are a bit strange because the negative feedback is taken off the speaker jack instead of one of the transformer taps. "Using the loop on a modern 3-channel rectifier changes the tone pretty dramatically (we model the amp with the loop bypassed). - Amazon , 3 , Amazon. Even just a short cable. Some of the add-ons on this site are powered by. ", "When modding Marshalls for higher gain sometimes the modder will decrease the input frequency response to reduce noise and fizziness. A tiny change in the bias point can make a big difference. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register. The default Depth value when you select the Euro Uber model is equivalent to the amp's fixed depth circuit. The seperate eq and the tube driven effects loop were added for that situation. ", "It's a single-ended power amp with negative feedback and bias tremolo. The model is MIMIC'd and is extremely accurate. When you turn it up you get that same squishy rasp that you are hearing. It is equivalent to the Drive knob in the Axe. Most modern hi-gain designs use some form of HF rolloff like this. The phase inverter, however, is a 12AT7. Old Plexis didn't do this because they had good transformers. The circuit number, i.e. ", "The topology of that model does not support a bright cap and the actual amp has no bright cap. You are using an out of date browser. A quick glance through the extensive roster of Friedman Amplification reveals a who's who of musicians from Eddie Van Halen, Steve Stevens and Jerry Cantrell, to Richie Sambora, Joe Bonamassa, Dave Grohl and Bill Kelliher. Commensurate with (1) I found myself turning the midrange down as well as the bass and turning the treble up. This means the output voltage follows the speaker impedance. The model matches that particular amp very well. ", "Based on popular modified Marshall JCM800. The Axe-Fx triode models incorporate feedback so if there is a virtual cathode cap the stage is less linear in addition to having more gain. IOW, it's displaying 60 pF which is equivalent to 120 pF. They are expensive, though, and you won't often find them available second-hand. Concert 6G12 is a Brownface Fender Concert. I went through several before settling on this one as it was the best sounding by far. This occurs because the Legacy has so much negative feedback (12 dB, which is the highest of any amp I've ever modeled). ", "The Hook uses a "mu follower" instead of a cathode follower. ", (Boston/Rockman sound) "Plexi Jump. That IR is from my personal 1962 Vibrolux. If I were to make a modification to the amp it would be a switch to disconnect four of those caps so the supply is more bouncy at moderate volumes. The model is based on that. The clipping is extremely asymmetric. It's got some different component values than the Leeds which gives a different vibe. You can also try reducing the Master Bias Excursion but that won't get rid of the pre-drive control distortion. It's a Lerxst Omega that Alex Lifeson gave me. This is accomplished typically by putting a capacitor in parallel with the plate resistor(s) which rolls off around a few kHz. If you look at the schematics on the web the Maz-38 is shared cathode. The preamp is virtually identical to a Twin Reverb but 6V6s break up earlier than 6L6s. A Recto will start saturating the power amp in Modern mode at VERY low MV settings. Not sure if the difference in the cathode circuit is because Dr. Z likes split cathode for humbucking guitars or what. It lends a unique character to the tone. ", "The Treble control in a Chieftain is actually a "Preamp Presence" control, similar to the Presence control in a Dual Rectifier in Modern mode. ", "The SLO-100 is the loudest amp I've ever used. puppies care amp health for dogs books barnes amp noble May 9th, 2020 - explore our list of puppies books at barnes amp noble book annex membership educators gift cards stores amp events help auto suggestions are available once you type at least 3 letters use up arrow for mozilla firefox browser alt up arrow and down arrow for mozilla firefox Etc. ", "I hate to admit it but there is something special about a real Dumble. I have always tried to avoid that association as much as possible because the average Dumble lover is typically looking for a particular set of tones that may or may not be found in this amp. The AFS100 models are based on the actual amp but I think my version of #34 sounds more like AFD. Almost like a violin but with this really cool chirp on the pick attack. The schematics are readily available for both so anyone interested can see for themselves. The corner frequency is around 30 Hz. ", "The Pull Bright on the Volume knob is the classic "Bright Cap" which engages a capacitor across the potentiometer. ", "The power amp is based on a typical Marshall 100 watts power amp of the same era. If you like the base Dumble sound but want a little more gain without the fuzziness of a Fuchs try the Carol-Ann models. Modern AC30's don't have this flaw. ", "The Super Reverb model is "Diaz Modded". When you crank them up it smooths out. Dave Friedman's extensive knowledge and pursuit of tonal superiority inspired him to develop his own series of production amplifiers under the name Friedman Amplification. The model is based on schematics that were given to us that supposedly accurately represent Robben Ford's Dumble. I don't like it in the middle. Increase the Damping parameter to increase the negative feedback. ", "We got our reference Deluxe Reverb out of storage today, hooked it up and measured and compared. So cool. If you continue to use this site we will assume that you are happy with it. That coupled with the resonance magnification of the speaker impedance causes frequencies around the resonance (in the 50-100 Hz region) to distort early. Yes, Mr Friedman has outsorced the production to some USA based company that builds amps for more brands, but he checks each amp before shipping to a customer/retailer. Enter your email address to be first to hear about our new products and special offers. I own three of them and they are that fizzy. ", "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. ", "The only amps with a bright cap on the MV are Dumbles and their various clones/derivatives. turn the Mid, Treble and Presence way up; turn Norm Drive and Bass down a bit. ", "The Plexi 100W 1970 model is a non-MV "Plexi". ", "SLOs are brittle at low volumes. That would allow a hotter bias with longer tube life at the expense of slightly less volume but JCM800s are ungodly loud anyways so", "Based on the Santiago #34 modifications. Some distortion pedals also do this. You can soften the JCM800 attack by lowering the Triode Freq values. So many great choices out there and all are better than anything ever produced before. ", Clean: based on HRM circuit, Clean channel, Ford: based on schematics of Robben Ford's #102 Dumble, Overdrive channel, Pre Amp Boost (PAB) OFF, Ford PAB: same as Ford model, PAB ON (bypasses the tone controls), Mid switch OFF, Ford PAB Mid: same as Ford model, PAB ON, Mid switch ON, HRM: based on HRM circuit, Overdrive channel, Mid switch OFF, HRM Mid: based on HRM circuit, Overdrive channel, Mid switch ON, "The ODS100 has two drive controls, one is right at the input, the other is in the lead boost section. ", (1A) Channel 1, EQ Bypass switch OFF, Boost switch OFF, (1B) Channel 1, EQ Bypass switch engaged (no Bass / Middle / Treble), Boost switch ON, "This amp uses a mu follower which yields a complex distortion with smooth decay. Just to be sure I just compared the Deluxe Verb model with the reference amp and it's correct. The amp is modeled assuming a 16-ohm load. ", "IMO the designs are poor because wait for it they exhibit a papery buzz. ", "The topology of the Fuchs is pure Dumble. Splawns don't have enough compression. ", "Don't be afraid to turn the bass all the way down or the treble all the way up. That's due to the cathode follower. ", "It's a Vibrolux. Sound is said to not be as good as more expensive Friedmans, Some buyers mention an inability to gain a clean tone, Said to not be great at keeping up with rock drummers in a band, 112 Celestion G12M 65 Creamback speaker, Controls: presence, JBE voicing switch, bright switch, volume, master, gain, 3-band EQ, XLR Cab Simulated output with Level, Axis, and Ground Lift switches, A compact and more affordable version of the JJ-100, Controls: 3-position gain switch, master, gain, 3-band EQ, Lightweight without sound quality being compromised, Tubes: 4 12ZX7, 2 EL34 (Preamp and power amp), Controls: Presence (universal), gain boost (overdrive channel), gain, 3-band EQ, 3-position bright switch (clean channel), volume, 2-band EQ, Rich, sparkling American-style clean channel. ", "The Subway Blues model was completely redone. ", "The design is weird as the negative feedback is taken off the speaker jack. A little asymmetry is good because it warms things up. Same transformers. The natural compression works well in keeping the tone tight and controlled and it performs well at bedroom volume or on the stage. I even have a PCB maker in my office so I can make and cut double sided boards for prototypes. Not sure why they did it that way but it is what it is. For a better experience, please enable JavaScript in your browser before proceeding. This reduces the bandwidth which lowers the hiss. As expected the models are extremely accurate. ", "The vibrato channel is loaded down by the vibrato circuit. "This particular amp exhibits a unique breakup characteristic due to its single-ended design and simple circuit. The Pull Deep switch engages a large cathode cap on the final triode stage. Power would be unsuitable at bedroom volumes! The frequency shaping is very different than most other amps. That's why the buzzing went away when you increased negative feedback. 5153, Freidman BE/HBE, Dirty Shirley, TripTik, Tucana, et. Everyone says "Bogner amps are dark". ", "My Uber is a very early one and probably different than later models. Our model is based on a 1981 2204 Master Volume JMP. This is a topic that comes up frequently on this board with lots of strong opinions in tow. ", "It's basically a Deluxe Reverb preamp with a cathode bias 6L6 power amp and no negative feedback. Turn down the MV to make it cleaner. Not sure if you watched the video, but Dave says that the Runts (which are PCB) have less issues than the rest of his line. Mesa always says things like "sounds the same as a IIC+" but the circuits are different and, probably most important, the knob tapers are completely different. He has recently worked on new recordings with MGMT, Neil Finn, The Cribs, OK Go, Tame Impala, Lord Huron, Baroness, Spoon, Interpol, and I Dont Know How But They Found Me[2], As a musician, Fridmann was the bassist and a founding member of Mercury Rev. It's a really cool amp. Answer: The inventor of Friedman amps is Detroit-born Dave Friedman. ", "Our reference amp has a 100 pF bright cap. However, you'd be surprised that a Twin isn't nearly as clean as you think. I just used a standard Marshall tone stack whereas the JMP-1 uses a standard Marshall tone stack but the pots are replaced with fixed resistors but those values don't necessarily correspond to the pots at noon. If you were to set the model's slider to the same position you would get significantly more boost. ", "The amount of treble peaking needed for an amp at a given drive is highly dependent on the guitar. ", "It does classic rock extremely well and has one of the best clean channels I've ever designed. Friedman Pink Taco 20W 1x10 Tube Guitar Combo Amp | Reverb ", "Our reference amp for the Silver Jubilee is actually not a Silver Jubilee. If you like the SLO-100 model you might want to try the Recto models too. IMO, the key to a MKIV is to use the TMB to get the feel and the EQ to get the tone. IOW all over the map. Try 32K. ", "The Quick Rod is a bit odd in that the Drive pot is linear taper. It's the infamous AB165 circuit which is very crunchy and bright and does not sound like your typical Fender. Then there is a digitally controlled 4-band graphic EQ which is the B/M/T and Presence. With many brands on the market and some vastly more popular than Friedman, when youre looking for a combo amp, its entirely possible that Friedman doesnt even enter the equation. Now, if you like, put a Zen drive in front on the BludoClean amp.or a boostand listen to how that clean channel wakes up fast for grittier leads and touch-responsiveness. Dave Friedman is the man behind the signature tones of rock icons Eddie Van Halen, Steve Stevens and Jerry Cantrell. 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. been wanting one for years, but I thought he wasn't making them any more. It's really just a bunch of EQ presets and it interpolates between them as you increase the value. Zero worries. Whatever sounds best. You can get all sorts of different distortion textures by playing with the two drives in conjunction with the tone control. This cleaned up this area of the build nicely. All Rights Reserved. The model is based on the Vibrato input #1 which has more gain than the normal input. With varying prices and different functions, there can be significant differences between Friedman amps. They're much brighter so I turn the treble down quite a bit. 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. ", "The real amp is a nasty thing. I based the model on information I've collected over the years about the mods that were done. In the actual amp the Treble control is re-purposed as a Negative Feedback control. ", "Some of the undesirable characteristics are what makes a particular amp unique. Often called the best amplifiers in the online guitar world, Friedman amps have an excellent build quality, high and low inputs, awesome loop and master, and are fun to play, requiring minimal tweaking. ", "The key to an SLO100 is to run the MV high so that the mids thicken up. For a given voltage into the power amp a 6V6 has about 70% of the headroom compared to a 6L6. When mounted in a typical cab the resonance will be in the low 70s. Dave Friedman (right) with Joel Hoekstra of Whitesnake [Image: Jeff Schultz] You can find simulations on-line but typically you would get close using shelving filters with frequencies of 100 and 1000 Hz. Just listen to Pete Thorn's demo of the Pink Taco 20-watt head - "no pedal required" indeed! Use the 5150 model and turn off the bright switch. I have to turn the presence way down.
