Hi Everyone, I was hoping I could get some advice regarding shopping for vintage deluxe reverb amps. I'd like to pick up a blackface or early silverface deluxe reverb, but the prices on the blackface amps seem incredibly high in my area (Ontario, Canada) when they come up (often $3000 ish). I have heard that there are relatively minor differences in the circuitry of the early silverface amps as compared to the blackfaces in the smaller combo amps of that era. What year did major changes happen in the Deluxe Reverb circuit? I'm not that bent out of shape about having a blackface as long as I could pick up an early silverface that would be similar with respect to tone. For the experts in old Fenders amongst us: 1) What years are 'good years' for the silverface Deluxe Reverb? 2) What would be a fair price for those amps? My apologies if this has been asked 1,000,000 times before. Thanks!
