I've just done my first pedal mod on my well used 1985 boss od-1 pedal. I've always kind of liked this pedal, even if it was a bit mushy at times, but it was always smooth and kept the character of the guitar.

Anyway to make a short story long, I took out the original JRC4558DD chip. and replaced it with a Burr Brown OPA2134 chip.

Yikes, this thing has now got some attitude. It's clearer, less mushy/middy and the attack is edgier..and as for noise..well there just isn't any.

Really surprised at the difference a chip could make.

Now I just need some ideas for my boss od-2...that thing is just underwhelming, the overdrive is blah,the turbo boost lacks any mojo, and the output level is lame. How could they have gone so wrong after the od-1??
