Personally I hate the 39K resistor. As with the majority of musical instruments and equipment, an amp can be seen as a significant investment. In other words that filter requires headroom to function properly, as does the presence control of any amp where it's a component of the feedback loop. The Drive switch sounds virtually identical whether left or right. - BE100, the king of the Friedman amps. ", "That's how our reference amps work. It may not display this or other websites correctly. David Friedman was born and raised in Detroit, Michigan. I find the BE/HBE a little too boomy and scooped. ", "The Tuc 3 is very very tolerant of most cabs and speakers, unlike say the OD2. It's worse on lower notes because lower notes have more energy and charge the cap more. Set up as normal, plug in the XLR and youre ready to rock. With the Presence Shifts off they are very different sounding. The gain staging, overdrive voicing and output stage are night and day to ANYTHING Mesa, any owner of the real amp would attest to that. 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. "A Blackface preamp into a cathode-biased 6L6 power amp with no negative feedback. ", "Got out the reference amp and it sounds the same. I forget the actual values but I'm pretty certain if you look at the Cathode Resistance value for those amps it's pretty high. Clearly it doesn't give you the full experience of the full amp, but is a good tonal taster. Snapshot - try the M25 GB speakers, V30s, or a combination with the Friedman amps. Dave has been building, modding and repairing amplifiers for many of the worlds biggest stars for the past 25 years. Funky amp.

Perhaps the better quality components. The bright cap is different, the mid resistor is much greater, the source impedance of the drive "pot" is different, etc., etc, etc. To simulate the lower gain input simply set Input Trim to 0.5. ", "The reference amp is the later, single input version. Dave Friedman has covered it all! In actual levels of gain with the two adjustable gain controls, the amp has a maximum gain level very similar to the Triptik, the setting of these two controls with respect to each other is critical. When you do this the low notes get very muddy. This is the "Triode 1 Plate Freq" parameter. Friedman Pink Taco 20W 1x10 Tube Guitar Combo Amp | Reverb David Lawrence Fridmann is an American record producer and musician. With all controls at noon the tone stack is equivalent to the real amps fixed tone stack. You can reduce the compression in the models by lowering the Compression parameter in the Cathode Follower section. If you look at the schematics on the web the Maz-38 is shared cathode. This causes a double resonance and one of the resonances is at a very low frequency. 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. I forget the actual values but I'm pretty certain if you look at the Cathode Resistance value for those amps it's pretty high. He gave up his role as a touring member of the band in 1993 to concentrate on producing other artists. Friedman Runt-50 50W 1x12 Tube Guitar Combo | Guitar Center Weird Bridge-T sorta tone stack. Most "Class-A" amps use a shared cathode bias but the Chieftain uses separate cathode bias networks which results in less bias shift so there's less fizz. ", (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. It can fill arenas and venues of any size and requires minimal handling for fantastic, on-the-spot results. An AA769 Dual Showman Reverb on the Vibrato channel will have similar gain as it has three gain stages. Certain Bogners and Diezels have a unique type of feedback circuit. On an SLO100 all the way down is around 8:00 and all the way up is 6:00 so 50% is around 1:00 not noon. ", "It is a very bright model. This was requested by Metallica's engineers after the main IIC+ models were updated, and it's part of Metallica's live sound. ", "Brootalz uses the Engl Savage presence network which reduces negative feedback as the control is turned down causing an increase in volume. When using the LD1 modes the Presence control doesn't do anything and is as if the control were at 10. This reduces the signal level substantially and lessens the amount of blocking distortion.". 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 FAS Modern model is similar but biases the stage more towards the center.". If youre looking for crystal clear sound then this may not be the amp for you as its been built with rock and the associated distortions in mind. [12] Kod ljudi i viih primata, urina kiselina je krajnji oksidacioni proizvod metabolizma purina i izluuje se u urin. ", "The tone stack on a Boogie is pre-distortion.

", "Some amps have a fixed depth circuit, e.g. A tiny change in the bias point can make a big difference. 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 amp block only supports Off and On and I figured people wouldn't know the fine details so a separate model seemed the easiest solution. The Recto1 models are based on our Rev. Almost like a violin but with this really cool chirp on the pick attack. ", "JCM800s sound better with a hot bias IMO. This is not a problem with our virtual amps though. ", "The amp uses linear taper sliders. to get the tone to match. We love the striking white finish for people to take note of this amp on the stage in the beginning before their breath is taken away by its powerful capabilities. ", "It's a single-ended power amp with negative feedback and bias tremolo. 'Noon' on an SLO isn't actually the knobs at half-way. Both in mint condition. This happens when the pots don't have a flat spot and/or the pot is rotated within the mounting hole. Compensate with the Level control. $249.00. Similar to a 1987x but with some different values and voltages in addition to the MV. On the Axe-Fx you might need to set the Bass to 3, Mid to 7, etc. ", "They're actually pretty decent little amps and sound great when cranked. dave coleman author meet the writer amp discover his work "Resea del editor cryptozoology (n.) . ", Channel 1 (12AX7 preamp tubes), Master Volume bypassed, Channel 2 (EF86 preamp tubes), Master Volume bypassed, "The DC-30 is basically an AC-30 copy. "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. Amp designers use cathode caps to shape the frequency response. ", "There's a 0.68uF cap on the second triode. The V1 and V2 are based on Mark Day's BE100. (IIC+), "On a Mark IV (at least on our reference amp) all three controls have a Log10A taper. The knobs are a bit confusing on a Badger. The problem with those "Mid Stage Drive" designs using a Plexi drive network is that if you bypass the drive pot with a cap (bright cap) you also bypass any grid stoppage and the next stage goes into blocking distortion very easily. Power would be unsuitable at bedroom volumes! There is no right or wrong. Some amps have a second drive control, typically called an Overdrive, located further downstream which allows you to balance the pre- and post distortion. FWIW, this is a terrible loop design but "it's a Dumble" so it's all part of the mystique. Totally different preamp topology. They exist solely in the virtual world. I could never get the model to sound exactly like our reference amp. The knob closest to the input jack is labeled "Gain". ", "I have a Mark IIC+, a Mark IV, a Mark V and a Triaxis. I really liked the idea of driving the tonestack from a common cathode stage as opposed to a cathode follower like a Marshall because it got rid of some of the artifacts I don't like with say a JCM-800. Check Price Personally I don't think the Dumble topology lends itself to that much gain but I didn't design the amp. ", "It's loosely based on a Recto but with tighter bass. It is equivalent to the Drive knob in the Axe. There is a treble peaker on the Output pot. Put a Filter block in front: Type: Peaking, Freq: ~800 Hz, Q: 0.707, Gain 12 dB. With a 20 watt compact combo, the JJ-Junior lets you take the stage, studio, or jam session with total confidence. So when the knob is at noon on a Bogner it's similar to 8 o'clock on most amps. I don't think it matters where they are made or which construction methods are used as long as they sound good, use good parts, and are reliable. Dave Friedmans first signature amplifier, the SS-100 was created in 2011 to the exacting tonal demands of guitarist extraordinaire, Steve Stevens. This cuts the bass, shifts the midrange and lowers the gain slightly.
