Don't get me wrong, the Bogner LaGrange is a nice sounding overdrive, I have one on my board.....BUT.....it isn't capable of getting those old, old early ZZ Top sounds found on their first three or four albums. Billy's guitar tone on those records has an almost fuzzy sound blended in with that good old tube crunch that we all love. Very interesting guitar tone! But no matter what gear that I've gone through over the last twenty years, none of it has THAT sound. It's a real mystery to me. I had a Fuzzy Drive pedal years ago, that was cool but wasn't really in the same ballpark. Any ideas out there on how to get the Reverend's old 70s tone?
