I always wanted to try one of these and it delivers in spades but I have a number of other pedals that get close enough to the sound. If you want to go with a no amp setup or used as a standalone recording rig this works like a charm and produces clear, organic tone. Run in your signal chain it provides an unmatched amount of headroom and power. Very good condition, functions perfectly, no velcro, chassis has some paint chipping as pictured, comes with power supply, original packaging not included. Sounds amazing and packed with practical features.

Channel B tips its hat to the foundation of rock bass with solid punch and a sweet break up available when things get down and dirty. Cold Fusion lets you live in the limelight with the best of both worlds while Hot Fusion lets you take center stage with searing bass from a focused distortion to synth-like growls.
