My very favorite overdrive pedal sound is from my beloved old silver Jekyll & Hyde (the Jekyll side of course, with the gain turned all the way down, the level cranked, and tone to taste). The newer versions aren't as good to my ear but are still good. I also own an older Route 66 that sounds the same on the drive side. And I recently bought a Route 808 that while it doesn't sound magical like Old Silver, is very very good. Who else wants to join the VS OD club?
