This is a 6v6 x 1, 12 ax7 x 1, 10 in speaker, single knob tone combo that is hand wired eyelet (Fender style) construction made in China, sold on line for around $200. Mike Fugazzi reported his observations on some boards recently. I played a brand new one today and am very impressed. Almost seems like an amp intended for harmonica. Excellent tone and no feedback up to surprisingly loud. The half power switch and boost control provide a useful variety of tones. The half power switch reduces the volume and rolls off the highs to much but this can be remedied by turning up the tone. The boost and half power switch together produce lots of distortion with reasonable feedback resistance. My effort to inspect the circuitry and try different tubes was hampered by a screen in the pack panel opening preventing access to the innards, and inability to get the back panel off! Stuck like it was glued! This amp is one of the best small harp amps I have tried, irrespective of price.
