Acquired in February 1999, this item has been stored away since being tested. It's a unique "guitar preamp" from before the recent modeling era, but unfortunately, it didn't suit my tastes. Like a typical effects pedal, it requires a separate guitar amplifier or a standard power amplifier for live use. It's a beautiful item with no scratches, and a copy of the instruction manual is included. Please note that, unfortunately, the original outer box in the photo is not available.
