Boss DS-1 Ultra Seeing Eye Mod Kit

Includes "Keeley" style knobs & detailed instructions!


The DS-1 out of the box is a fair sounding distortion pedal. Change some of the capacitors, diodes, and resistor values and you get Tone with a capital “T”!  Must be heard to be appreciated!  

This auction is for a Boss DS-1 All Seeing Eye/Ultra Mod Kit only – the pedal is not included! 

I’ve done this mod many times and every time I complete it and plug it in I am amazed at the tonal difference from the stock version.

·         Includes Metal Film resistors, Panasonic capacitors, Silver Mica Caps, and the classic style pointer knobs!

·         These are the highest quality components you can find. All For under $20!  These are the same quality and type components on the Keeley mod - check my feedback - this mod rocks!

·         INSTALLATION IS AVAILABLE FOR AN ADDITIONAL $17.50 ($37.50 total including return shipping in the CONUS).

·         INSTRUCTIONS ARE E-MAILED TO THE PAYPAL E-MAIL ADDRESS - If you don't receive them, check your spam folder.



The Boss DS-1 the All Seeing eye/Ultra mod kit offers the Finest in Marshall-Amp Tone-In-A-Box!!! Perfect for tones like AC/DC, VAN HALEN, AND STEVE VAI.

Flip the toggle switch and you get the DS-ULTRA mode! This mode gives you a big tube-like sound. In the Ultra mode an extra LED boosts the volume output a little which is great for using the DS-1 as a pre-amp to push the amp or to fine tune a low distortion sound on the unit.  Flip the switch back and you get the classic Seeing Eye Mod (SEM) version of the pedal for high gain, tube- like distortion! 

Detailed instructions will be e-mailed if needed – there are versions all over then net and Keeley allows this mod to be freely distributed.  This mod corrects the bass response and gives you a fuller, more powerful tone-very tube like. This mod is not difficult if you have patience and some soldering skills. 

This mod is designed for the newer Made In Taiwan model-your circuit board should look like this:
