Hmmm. Reviews are limited. It's a fairly rare amp. It's in mint condition. I played a strat through it and it actually sounded pretty good on the clean channel. From what I've gathered, it will stay clean at outrageous volumes. If it takes pedals well, it could be a great back up amp for the JC. The price seems like a steal to me for a 3 channel amp with that much oomph. I would likely never use the drive channels, but who knows? It could happen I suppose. As much as I love my JC 77, I keep having to maintain it (it's old). Seems like a good back up is a no brainer. My JC 55 is just a touch underpowered, and my 120s are never getting gigged again unless I find myself playing a stadium show.
I'm seriously thinking of grabbing this.
