This is an overdrive pedal from Empress, a high-quality effects pedal manufacturer. It's a pedal that recreates the sound of a Fender tweed amp, and I've been very fond of it, but I'm selling it as part of a decluttering effort. This is a very rare pedal as the manufacturer has discontinued production. It works perfectly fine. However, there are traces of sticker removal on the back, so please refrain from purchasing if you are concerned about this. I will ship it with the original box and instruction manual.
