Well built solid pedal. #1 functionality I use the most is blend knob which allows you to use a cleaner distortion amp mixed with what I believe to be a Marshal heavier distortion amp output. You can lower the distortion on Gain B, and raise the distortion slightly on Gain A just to get the slight amount of grit to suit your desired sound. I am selling my Wampler Plex Drive to fund this pedal. Impressed with how far Fender pedals have improved. Hope to buy more of the recent Fender pedal line. As always SamAsh is #1.
