This is a handmade analog guitar pedal in ky ,, with the marshall 800 design circuit tone. Marked number 3 ,sounds killer, true bypass, covers ,blues rock. And heavier..... The lables on the pedal are contour, tone,volume, and gain.... they were painted on the casing, backwards. So I labeled it correct, no issues in working, price reflects issue, if interested please call or text thanks dj show contact info
