Boss SD-1 Super Overdrive Modifications

$ 28.95

The Fromel Electronics modification kit for the SD-1 retains all the warm, overdriven characteristics of it’s unmodified counterpart but pushes it into thick, crunchy British style breakup. The modified SD-1 can also clean up wonderfully, responding much better to picking dynamics and will really sizzle when you dig in.

This modification kit takes things one step further than every other kit out there and replaces virtually every stock capacitor in your signal path with high quality audio grade capacitors. Additionally, the kit includes vintage 1N34A Germanium Diodes, a new op amp and socket and a water-clear bright LED. The result is lower noise and better, more articulate tone.

Included in this modification kit are detailed instructions; including photos, and all the parts you will need to complete the modifications.

NOTE: in 2017 Boss produces the some pedals with surface mount technology. This mod kit will not work on the new Boss pedals with a surface mount PCB. Review the image with this product listing for more information.


If you have basic soldering skills and can follow directions this is
an easy project that can be completed in about 1/2 hour.

Don't pay hundreds of dollars for a Boutique overdrive when you can upgrade your
SD-1 for much less.

This is a kit to modify your pedal and there is no pedal included in this kit.
