Basically I have a Fab Overdrive and i find it sounds better running it BEFORE ,y BOSS ME-50 in my effects chain. I have it boosting the input a fair bit, but it sounds really good on a distortion preset.

Is boosting the input of a multieffects processor a bad idea? Could this much signal gain damage it in any way?

Thanks, hawk

PS: The way i see it it isn't much different than if i had active EMG's, or an afterburner boost or something like that in my guitar....
I used to run a TS-9 before my XT Live for added boost sometimes.

If it sounds good, do it.
