I have been thinking of a new pedal to augment the punch of my new CeriaTone 50 watt Plexi. I have a FuzzFace but I am thinking more of a tube screamer type device. I had a stock Blues Driver at one time and liked it but gave it to someone else who neede it more than I. Now I am thinking of getting another one from Keeley. Has anyone used the Keeley modified stuff like the modded Blues Driver?
