I have a 1971 non-master volume Twin Reverb, beautiful condition, play great. Not even that heavy, as it has stock Utah speakers. Trouble is, I rarely use it, so I have bought a Fender Rumble 500 bass amp, as a 'cover all' amp. Did an AB test with a USA Tele. Result- of course the Twin sounded better! But...the bass amp wasn't bad either. I need the amp for live work which will go through a PA, when using guitar. By the time a Twin goes through a desk and PA speakers, and is mixed with band sounds, who honestly is going to be able to differentiate and really know the difference? I now have a classic looking Fender amp, with XLR out, that I can use with my 5 string bass too, and it more portable. Ha, I dare to be different! I've owned and used a lot of amps, and I love Fender hand wired amps, but come on SS users, use your amps with pride! So the Twin is advertised. I may regret it, we'll see.
