I have a number of stompbox effects pedals (delay, etc) which would be nice to use in live shows for mic'd instruments (e.g. flute). Currently, if I try a setup like:

mic -> preamp -> pedal (either by inserting it or from the direct out) -> mixer

it works to some degree but not very well, I'm guessing due to impedance mismatches between the various devices and perhaps other issues since this is not the intended use. So I'm wondering if this would work better:

mic -> preamp -> reamp -> pedal -> DI -> mixer

Kludgy - yes, but I'd rather buy one reamp than loads of effects racks. I don't have a reamp (so can't try this) and have never used one before. Keep in mind that this is not for recording purposes, but rather for live shows where it's ok if the sound isn't pristine. But the sound shouldn't suck either, have lots of buzz, etc. Basically, is there any merit to this idea, or anyone have other ideas how to accomplish the same thing?

Also, I imagine that these stompbox pedals are really optimized for guitar, but suspect some of them could sound good used otherwise. thanks for any input.
