I was told it was a "Gretsch Treble-Bass Booster but nothing on it says anything about Gretsch. Someone wrote on the box in pencil "Gretsch" but that's it.
There is no tag, no serial number. The case is chrome, stamped with "Treble Bass Booster" on top, "Bass-Treble" on the front by the knob, "Guitar" on the input side, "Amp" on the output side and "Made in Japan" on the bottom.
The box says "Treble Bass Booster" on it and on one end says "MEDE IN JAPAN" yes, its printed wrong on the box. I have no idea what this thing is so I figured you kind folk might know or at least be interested in it. I can supply more pictures if you like. Thanks!
