Product Description

This Keeley Mod is going on 9 years as the respected measure of tone! The DS-Ultra is our most popular modded distortion pedal!
DS-Ultras Used by the guitar gods like Vai and Lynch.
The Keeley Modded BOSS DS-1 Guitar Effect Offers the Finest in Marshall-Amp Tone-In-A-Box!!! Perfect for tones like AC/DC, VAN HALEN, STEVE VAI.
JUST TALKED WITH STEVE VAI at the NAMM Show and he told me how much he loves the two DS-Ultras he has!
The Extra LED increases the volume output of the pedal a bit, 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. The way we engineer the mod, it has increased 2nd order harmonics and tube-like qualities.
