Today I saw an Acoustic tube amp at a local vintage guitar store. Anyone know anything about these? All tube, and was brown and tan in color. It looked awesome. I'm sure it was a 50-60 watt guitar head, but was curious if anyone knows anything about them? It was missing a power tube, and I didn't really look to see what the tubes were or what exactly the model number was. The store has hundreds of old amps, and I didn't have a lot of time to spend. However, I keep thinking about it.
