King Gnu Tsuneta's favorite BOSS multi-effects processor, the ME-50. Cleaned and tested. There is some paint chipping on the back and some minor scratches near the pedal, but it is generally in good condition. The compressor knob was bent, so it has been replaced with a genuine variable resistor. The height is slightly different (see photo 9), but there are no issues with operation. Accessories: Instruction manual only. An adapter is not included, so please use a general-purpose one.
