26 Bob Howard 2 months ago Cool! My buddy has one and it runs just fine off a rechargeable 12 volt garden tool battery. Interested to hear what you think. Well, the Smicz amp came and I’ve been playing it all day. I am surprised how good it sounds. Like a Princeton, but a tad closed in. And through an extension speaker it’s quite big. Not as much volume as a Champ, breaks up easily and the reverb is useless, but for a battery op it’s remarkably good.
