Ah, I learn something new every day. That means my amp already have the little mod I though about doing, and it's even switchable, haha..

Thanks!

Ok, forgive me my ignorance here, while I try to educate myself a little. That master volume pot have a pull bright switch, and I guess that why those caps are there.
