Boss SD-1 Super Overdrive Modifications

$ 19.95

The Supreme Mod SD-1 still retains all the warm, overdriven characteristics of it’s unmodded counterpart, but aslo pushes into thick, crunchy British style breakup.  It’s a wolf in sheep’s clothing…if the wolf looked like a boutique, handwired amp and had the bite to match.  The modded SD-1 also cleans up great, responds well to picking dynamics and really sizzles when you dig in.

This is not called the supreme mod kit for nothing. Included are detailed instructions, including photos, and all the parts you need.  This Supreme mod kit takes things one step further than every other kit out there and replaces virtually every cap in your signal path with high quality Film and Mica caps. No Cheap ceramics or tantalum caps here.  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 tone. Why be happy with a Super Overdrive when you can have a SUPREME Overdrive?


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 $19.95.
