In great working order and condition, made in USA and is part of the DOD JASON lamb era of pedals from the 90's! The FX 100 is the predecessor to the bad monkey and shares a similar circuit as the FX 101 Grind. Sounds great and very versatile. Works really well on low gain settings for overdrive, crank it for saturation and when you use this before another distortion you will be in tone heaven!
