I like to use a fair amount of pedals (looper, delays, mainly non-effects). I have been using a Fender Acoustasonic 30 DSP with just the preamps in my guitars (Fishman Aura in the Martin, and stock crappy Ovation whatever). I have heard from many people that a mic and PA system gives the best sound. I'm wondering what other people think. I have only ever used a PA system if thats all the venue has to use, and I have had some minor issues with background noise going through the looper. Would that be just a poor set-up thing or is that a normal occurance? I like how my Fender amp sounds, but the people I play around think I should be on the mic... Any imput is welcome.
