I just got mine yesterday and out of the box, it's much better sounding than I was expecting. I changed the stock Chinese tubes with some JJs I had on hand and it sounds even better.......warmer, fuller and with less buzzing when the volume knob is maxed. The stock speaker sounds pretty good, and my general impression of the amp is that it's well put together and built to last. Not something that everyone will want or need, but it sure fits in with what I wanted. Plus it looks cool.....besides, how can you put a value on the nostalgia factor?
I bet Fender sells a ton of these little amps.
