An awesome little amp. Tiny, but not boxy at all. Great tone. Yes, there is some hum when idling (even when the volume is on zero), but that's just part of the design, not a fault. They all do it! And it isn't noticeable when playing. I love this little amp. (My other amps are a '66 BF Princeton Reverb, and a '72 SF Deluxe Reverb). It's expensive, but worth it in my opinion. Stop dreaming, start playing !!!
