PEDALS PROTO OD III

The ProtoOD is based on the classic TS808 tubescreamer circuit, but with many modifications. First, the input & output buffers have been removed for increased transparency, increased input impedance & decreased output impedance. A toggle switch has been added to switch between true Mosfet clipping, 5mm Red LED clipping, and a diode lift (clean boost). The overall gain range is greater, although LED & Mosfet clipping has a higher threshold, so the overall amount of distortion will be slightly less than a TS808. I've installed a charge pump in place of the battery that up converts a 9V power supply to about 25-26V for greater headroom. Lastly, I have made the low-pass (or high-cut) and high-pass (or low-cut) filters variable. In brief, this means you have control over of the high & low end roll off -- giving you back control over your tone that the TS808 lacks. Inside, there is an internal trimpot to control the center frequency of the TONE control, but it will ship set at the stock 3.2kHz setting. I use high quality components throughout, including 1% metal film resistors & 5% metal film capacitors, and true mechanical bypass switching.
