i'm also interested in finding out. Unfortunately the tube boogie pedals are way too hard to get and expensive for me right now. Anybody try the AMT California sound pedal?? supposed to be an 80s boogie sound.
My buddy has one on order (WAAAY back orderd and it's taking forever) - I'll let ya know. From what I understand it is boogie voiced, but I think that it's supposed to be more Recto than Mark IV.
