Thanks Chas, for the follow up on that. I sure didn't expect it to be close to the K4 for $149 but for that price it sounds like it is perfect as a rehearsal amp. Just can't beat that price. I really think you were smart to buy it for that.

Although the K4 isn't really a guitar amp there are a number of guitarists using it. While this video is by a rock guitar player rather than a jazz guitar player he still gives a good rundown on why he likes to to use the K4 for guitar.
