Looking for advice from those with more expertise. I have a mid-1980's Seymour Duncan Convertible 60 watt tube amp like this: http://www.diyguitarist.com/GuitarAmps/Convert60.htm
I purchased it used in 1997. In the last year or so the preamp quit working -- so plugging into the input jack provides no sound. The amp has an effects loop on it and if I plug directly into the effects return jack -- bypassing the preamp -- I do get plenty of sound but none of the vol, tone, OD, of the preamp. To avoid this amp becoming a large paper weight I am considering adding the Boss FDR-1 Fender Deluxe Reverb modeled pedal to act as the preamp. My hope would be to salvage the remaining operational components of the amp while at the same time gaining some Fender -- and in turn Jerry -- tone. I am merely a hobbyist/bedroom player. My questions are:
1. Does anyone have experience running directly into an effects return jack to bypass the preamp and go directly to the power amp? and
2. Any thoughts on the Boss FDR-1? It seems to get pretty good reviews online.
Thanks for any input.
