Back in the day and I was buzz bombing a couple of Marshall... I would completely disconnect the tone controls. It gave you a bit more brightness and gain straight in. Using 1meg pots can make a difference too. Lately I donít play as many large venues with large gear and need to be more versatile. I find using a 2 channel amp helps a lot . One Marshall voiced preamp and one Fender voiced preamp... also a boost and a fuzz pedal depending on how much dirt I want. It gives you a lot of combinations. AND.. I use a footswitchable speaker attenuator. I donít have a sound man riding levels as much as I once did. So I set the attenuator just to take the edge off and when I need to get on top of the mix I turn it off. You can do a similar thing with a switchable boost or attenuator in an effects loop but imho it doesnít work as well. Too finicky. I had compensation caps on a couple guitar volume controls a while back... but with this set up I just leave everything stock anymore. Just remember there is more than one way to Egypt and your mileage may vary. Hope this helps. Honestly... Iíve found that you make more of a difference practicing technique than looking for the ďmagic modĒ. Tone really is in the hands..
