And here I was thinking that @DrBGood was the only one who ever found great deals on amps Picked this one up on Facebook for the low, low price of $100. Needs a little TLC - pots are pretty scratchy, and the ground on the power plug is snapped off, so I'm gonna need to clean it up and fix the plug. Biggest issue - channel A doesn't seem to work. Hoping it's just a bad solder somewhere. Channel B works great, though, and I mean, the dirt is what you buy a Sunn for, right? The semi-parametric EQ works great and the ginormous spring reverb tank is still churning out some nice, washed-out, surfy sounds. In fact, this is one of my favorite reverb tanks I've ever used. Speakers seem to be good, too. This sucker is LOUD. Gonna clean it up and play with it a bit - it's in good condition for it's age. Definitely sounds like an solid-state amp from the 80's or 90's - flat cleans, somewhat nasty, thrashy distortion - but it's definitely cool in its own way. I actually really like the off-clean tone, sounds kinda like a loud clean amp with a torn cone or a failing diode. I've never owned a Rat pedal, but from everything I've heard, this kinda has that vibe as you turn up the drive. Looking forward to playing it more!
