any way to run 2 distortion pedals in paralles w/ 1 in and 1 out?

[Lumpy]

i have a tuner pedal w/ two outs. i would split it, run 1 into my rat/pedalboard and then 1 into the fuzz straight into an amp.

hmm.

i do have a peavey power amp. could i just split it off the tuner, and run the fuzz pedal directly into that?

Sounds right. The only bad thing about using a tuner to split the signal -- one amp will always be on, while you're tuning. There won't be a 'tuner mute' function any more (one output on the tuner doesn't mute). But it would be fine way to test drive your setup, before you spend money on more cables or splitters.
