These amps are really common with collegiate jazz bands. Unfortunately, even tho the cabinets are reinforced with metal L channel they break easily. On stage, every one I've ever seen has had the wood shattered. If it's a personal amp, I'd expect it to be better cared for than one used by a bunch of college kids, after being thrown into the back of vans for gigs.
They are "clean machines", and that chorus is well renowned and respected. I've got an old Roland EP, and it's a great piece of gear, like all Roland products.
