People are dicks. The dude was asked how he dialed in his amps and he showed them, then they unloaded. It wasn't like he was a dick or talking down to people. He gave some decent advice, at least a good way to find a starting spot to dial in from.
The fucking internet loves to dwell on semantics.... "It's where the pots are the most sensitive, not where the amp sounds the best"
Well dickwit... if that's where the pots are the most sensitive, then plus or minus on each knob should have the most effect on the tone shaping and get the closest to what you want with the least amount of turning, right? fuck.
Cool technique, and it works for him.
However, having built and studied guitar amps, I can say that what works with one pre-amp configuration won't always work for another. For example, there can be considerable interplay between a preamp vol and the tone stack (MESA amps have this) that can change how and where the tone stack peaks. Within the tone stack there is interplay as well.
His technique does seem like a good starting point.
If they every came out with a mini version of the electra dyne, I'd be all over it. I love that amp, but it's too much amp.You mention Mesa and that is what threw me from his method. As soon as he went from the first knob to the second, I thought, if that was a Mesa now that he dialed in the second, he'll have to go back and tweak the first. Boogies tone stack are very connected, and the knobs seem to all interact together. Which is probably why I've had a love/hate relationship with them. I hate to twist knobs, but once you get them set, they do sound great.
