I've got a 100w valveking head that i use for all my guitar work. for my lead stuff i have a boss dd-3 set with a quiet delay and the reverb on the amp between 4 and 6 to help with the tone and for my rhythm stuff i turn them both off. is there any way i can make a footswitch or something that would make it so i don't have to walk back to the amp to turn the reverb down by hand?
