Do any of you have experience with Robert Keeley modified pedals? I have the Blues Driver, and the DS-1 Distortion pedal. I absolutley love the pedals I have and am wondering if anyone else has experience.

I think Keeley mods are a matter of taste. I have friends who use Keeley modded pedals and swear by them. Me, personally, I had a Blues Driver and a Sparkle Drive modded at one point and ended up selling the modded versions and keeping the originals. I don't know if I was just used to the stock versions more or if I just didn't like the actual mods. The added low end muddied up the Blues Driver for my taste and kinda the same for the Sparkle Drive. It really depends on what you need out of the pedal, what amps you're using in conjunction, and personal taste. For some, I'm sure they're great.

I have a modded blues driver and I do like this pedal better than the original but I will have to agree with you that the sparkle drive is better without the mod. I have a non modded and tried a friend's with the mod and it almost turns the pedal into more of a distortion pedal than an overdrive pedal. I have had the chance to A.B. several keeley vs. non-keeley and for the most part I prefer the modified pedals. They seem to expand the effect (whatever it may be) beyond what the stock circuitry will allow.
