I have found another contributing factor in the difference in tone between
the two channels is the difference in coupling caps. The Vibrato channel
uses a .02uf and the Normal channel uses a .047uf. I switched to a .047 on
the Vibrato channel of a SF Super Reverb the other night because the owner
said that it lacked the punch of the Normal channel. This alteration gave
him the “punch” he was looking for.

A lousy amp will make a great guitar sound lousy.

 

Buy the Book!

I cleaned up my tab for Sonny Boy's Help Me and made it into a short book. There's a Kindle version for 99 cents, and if you buy the paperback you get the Kindle free.
