Check the listing for details. Boss DS-1 Distortion Guitar Effect Pedal Modded READ INFO. Condition: Used. Listed at 86.00 USD. This pedal was made in November 1997 in Taiwan according to the Boss serial number decoder. It has been modded with two mosfets which replaced the stock clipping diodes. A socket was installed so that different OP Amps may be tried without the need to desolder and resolder each time. Unless you can do this yourself, the cost of having a pedal modded, is about as much as buying a used pedal in its standard form. Also a few capacitors were replaced which controlled the EQ curve. I would suggest doing your research regarding this mod so that you know what to expect before buying. The ON/OFF LED status bulb has been replaced with a purple crystal-clear bulb. This pedal is functional and is being sold as is. It may have scuffs and scratches from normal wear and tear that may not be visible in the photos. Ask questions if you need more information.
