I generally try to use a pedal to enhance what the amp is doing, not actually create the tone. :RoCkIn
Then you need a clean boost. I use a cheap Seymour Duncan pickup booster and it does wonders for my strat with it's weaker pickups.
Also, the pedal I put up there doesn't color your tone a whole lot.
Th key to gain with the Maz is cranking the Master up. It is not a preamp gain heavy amp. It does have a good bit o' hair, but the real magic happens when you crank the master past noon.
