http://www.rocketpedals.com The Archer pedal from the mighty circuit wizard, Jay Rockett , is a klon based drive that, in my opinion, maintains its' clarity when dialing up the gain, even better than the Klon. I love em' both...but with the prices climbing on the Centaur, the Archer at under $200 is a natch. It's a very heavy duty enclosure, unique to the Archer, and comes in very clean and handsome packaging.
I used my Gibson Les Paul R9 59 Historic with http://www.mojotone.com Mojotone PAF Clone pickups.
