Title: Adding TMB to a champ clone....
Post by: Stuff4bikes on September 26, 2021, 06:44:46 pm

I gave one of my old builds to a co-workers son who plays guitar in church.  It is a volume only champ clone but he plays at low volumes and wants to get some "different" tones at low volume....I am not much of a guitar player so I couldn't give much advise other than adding pots....
This is the exact board

Another thing you can do is either put in a switch to disconnect the -feed back loop (-FB) or use a pot to dial in full -FB all the way down to no -FB.
