I'm a big fan of Analog Man and have been collecting these items. I'm selling them to organize my equipment. The level knob has been modified to function like an Ibanez TS-808 circuit when pushed (push). Pulling (pull) the knob activates a Boss clipping mode, resulting in a Boss-style distortion. You rarely see these on the market, so if you're interested or a fan of Analog.man, please consider purchasing. I do not plan to lower the price at this time. Thank you.
