Keeley Effect Pedals - DS-1 Ultra Mod

SOLD - Contact us for more options
Free Shipping Eligible

This Keeley DS-1 Ultra Mod is Steve Vai's favorite pedal and it's easy to see why. It's the ultimate Keeley Seeing Eye Mod with extra goodies. The toggle switch allows you to select the Seeing Eye or Ultra mode. The Ultra mode increases the fidelity in high-gain modes and increases the total volume a bit to be used as a front end on a high quality tube amp. We've found the differences between this and the standard Seeing Eye Mod to best be heard through, say, a boutique amp like a Dr. Z MAZ 38 or a Bogner, a little more open and refined. Check out the difference for yourself and see why this Keeley DS-1 Ultra Mod takes the Boss DS-1 to a whole new level.
