I have a Reverend Hellhound that I wish had more Fender-like reverb. I don't have much experience with amps other than swapping tubes, so thought I'd ask folks here what's possible. I guess, main question is -- is it possible to swap the tank? If so, aside from the physical measurements of the tank fitting, what specs do I need to look for? I see numbers for input impedence, output impedence, ohms.. I really don't understand these things... If they all match the factory tank, is it possible to swap it in? Do they all need to be the same values? Thanks in advance!
