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 great amp can make a lousy guitar sound great.
A lousy amp will make a great guitar sound lousy.
