Effects order.....

sneaking a question mark in here...
Would a gz and kp go before or after my mxr fuzz?

I'm never entirely happy with pedal order, but my pedal order generally falls like this:
[high impedance booster to get as much out of weak pickups as possible] -> EP JR volume pedal -> Overdrives -> Distortions/Fuzzes (which are finicky about order, especially the fuzzes) -> Chorus -> Vibe/Tremolo -> Reverb -> GE-7 EQ -> Amp

Or in right-to-left order (the order the pedals would be on your board)
Amp <- EQ <- Modulation Effects <- Fuzz <- Overdrive <- Vol Pedal <- Booster (a wah here if you use one) <- guitar

Vintage effects (wahs, univibes, octavias) all seem to want to be connected directly to the guitar (first in order) and directly to the amp, so I haven't quite figured out what to do for those other than getting a true bypass strip with various pedals that play well together in each loop.

i'd put the GZ before. As far as the KP....thats up to you. you can use it to boost your mxr fuzz's sustain....or put it after it and boost it's volume.
