", "The Master Volume in a Blues Jr. is linear taper. The Friedman Amplification Dirty Shirley Mini 1x12" closed-back guitar speaker cabinet delivers much bigger tone than its size would suggest. The 1x12 Deluxe Tweed Mix cab is the IR. So the JMP-1 uses a fixed tone stack and then a digitally controlled graphic EQ. Bias tremolo works by modulating the quiescent operating point of the power tubes. This reduces the signal level substantially and lessens the amount of blocking distortion.". However reverse log taper pots are uncommon, difficult to source and cost more. That will make it somewhat flat but you still have the bright cap on the drive and the bandpass between the preamp and power amp. ", "A signal divider, which is more correctly called a voltage divider, is calculated by taking the resistance to ground divided by the sum of the resistances. Maybe one guy had a rough build, but that hardly speaks for anything beyond his experience. That IR is from my personal 1962 Vibrolux. More often used on tube hi-fi gear the controls are less interactive than a typical guitar amp tone stack and impart a different tonal quality.

Hi everyone, I am just wondering if anyone can help me translate the below amp mods performed by David Friedman on Adam Jones' Marshall to the axe fx. That bias excursion, however, causes the amp to sound more open when driven hard (at the expense of crossover distortion). ", "The IIC++ amp model is the same as the IIC+ with different tapers. The tone controls set the feel and the distortion texture, the EQ shapes the final tone. The result of a decades-long pursuit of tonal superiority by amp guru Dave Friedman. Answer: Every Friedman amp is made in the USA, using hand-selected components and to Dave Friedmans exacting standards. He found himself working at Andy Breuer Studio Rentals, one of the biggest gear resources for studio musicians on the scene, where he quickly developed a reputation as a tech.

Answer: Tube amps are undeniably a popular choice, especially for professional live performers. The cathode capacitor charges up and the bias point shifts dramatically. The difference is that there is less padding between stages 2 and 3 (IIRC). Tm on luettelo vuonna 2012 kuolleista tunnetuista henkilist. The voltage divider at the output of V1B is set to 0.078 which is based on the values that are indicated on the schematic for the set-point of the trimmer. Modern AC30's don't have this flaw. Custom Fractal Audio model. 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. I just sounds glorious. ", Bright channel (Normal channel: Bright OFF), "Early Dire Straits tone is a Vibrolux (Vibrato Lux model). For overdriven sounds some find it desirable. Amp designers exploit this and use different tapers to change the sound of their amps WITH THE KNOBS AT NOON. You must log in or register to reply here. Don't mess with extended parameters, basically don't try and redesign it. Concert 6G12 is a Brownface Fender Concert. This was/is done to compensate for the lack of a buffer for the fx loop. If the value is large the stage has more gain and the response is relatively flat. The problem with most cathode biased Class A amps is, 1: they aren't really Class A (more like hot Class AB) and 2: They go into Class B operation when they are overdriven. ", "If you want the sound of the non-SimulClass version set Triode 1 Plate Freq to 1350 Hz. The biggest reason Silverface Twins were cleaner is because the PI had less gain. ", "JP himself gave the models his stamp of approval. To my ears (and my measurement equipment), the Axe-Fx models are spot-on. It's called a Rockerverb not a Metalverb.

The amp will sound tighter and clearer in the low mids. ", "A Pro Reverb is basically identical to a Super Reverb except for the speakers (and faceplate). For cleaner sounds it tends to be objectionable. In certain contexts with the right IR it can be a cool sound. I bought it off a lawyer (surprise, surprise) some years ago who was in trouble with the IRS. One of the side-effects is that the effect becomes less pronounced as you play harder which makes it basically "auto ducking". Yek's Guide to the Fractal Audio Amplifier Models provides in-depth information about most amp models. Playing music isnt about technology, but rustic, authentic sounds that can capture a whole audience. The Normal channel is "normal" and corresponds to the 65 Bassguy Nrml model.

Dave Friedman has been building pedal boards for over 30 years. I prefer the AC-20 because it doesn't have a cathode follower so doesn't suffer from these problems. You can reduce this via either the PI Bias Excursion or Master Bias Excursion parameters. The HRM Dumbles have a fixed Marshall tone stack at the output of the lead channel. For a design that needs a lot of overdrive at a low volume, you do most of that and the harmonic makeup in the preamp. Bogners use a log taper. As there is no switch for this in the Axe-Fx it requires a separate model.

Find out more about the Friedman Amps and Guitars here: http://tinyurl.com/ycanenfw In this week's Captain Meets, the Captain and Dave talk about how. "Using the loop on a modern 3-channel rectifier changes the tone pretty dramatically (we model the amp with the loop bypassed). Turn down the MV to make it cleaner. In fact all stages in a Dumble typically have an AC load-line that's different than the DC load-line due to the load resistance being significant in relation to the plate resistor. 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. It is equivalent to the Drive knob in the Axe. This means that at noon the amp is nearly at full gain. I could never get the model to sound exactly like our reference amp. ", (Def Leppard) "The amp model you are looking for is "JMPre-1 OD1". With digital products I often see people set the MV higher than they would on the real amp because there are no sonic repercussions (i.e., pissing off the wife/neighbors, knocking Grandma's urn off the mantel, etc.). Since that mode has no negative feedback the speaker resonance has a tremendous effect on the sound. I didn't want to give it back and offered to buy it from him but he wouldn't sell it.
