I bought this amp brand new in 1982, its the silver grillcloth combo with the 15″ speaker. Can you elaborate on what you said here–disconnect your reverb out/in and place a single lead to bridge and bypass the spring reverb in your combo or head. I would like to try this but unsure how to do it. Also, i would like to swap out the original speaker but not sure what to replace it with, any ideas? Thanks

Hey Rick, sounds like you got a great deal on the amp! You must be thrilled. Yes, you’ll need the footswitch — unfortunately, it’s a bespoke one made specifically for this amp. You can order them from TAD, or check out this link for a workaround to disable the lead channel; otherwise, both the lead and clean channels will be active: http://www.stratopastor.org.uk/strato/amps/prii/footswitch/footswitch.html. Consider this amp a keeper — it took me ages to dial in good tones, but once you do, ooooh man, sheer bliss! Try this setup after you’ve disabled the lead channel as described in the link: starting from the left, bright switch on, volume at 6, treble 6, middle 3, bass 2, reverb around 2.5–3, and master at 4 or 5. Squeaky clean, I say. Good luck, Rick!

Richard- I just bought one of the Fender 75 head only models from GC Langhorne for $150. They thought it was screwed because when using reverb at all they got the loud buzzing sound. I cleaned the oxide off the RCA conns on the spring unit and it now sounds great, no buzz at all. But the lead master has no effect at all when turned. Is this shot or do I need to plug in two instruments for this feature to work? Or do you need the foot switch to work this feature? I just got it and have not tried these since cleaning it up. Its cosmetically great though. Thinking about getting a Celestion G12 75w 8 ohm single cabinet for it but maybe I should get a dual cabinet because it really barks and it may blow out a single. What do you think?
