I'm getting completely frustrated with this issue because google can't give me any good results when trying to address this problem. So I must make a post. here is my problem: I use a Yamaha audiogram 3 for recording. It sounds great using my sansamp for bass or my pocket pod for guitar when recording. But when I plug in any mics or even my acoustic pickup, the volume is too low to hear so I must crank it, which only adds in a bunch of background noise or hum to the sound. I wanna know what the fudgecicles is going on here. 3 things you need to know: 1. the yamaha has a preamp built in 2. the mics are almost brand new (1 sm57, 1 pg48, 1 overhead thingy I got from a church) 3. the acoustic soundhole pickup doesn't sound like it has anything wrong with it, besides the drop in volume & the noise due to turning the preamp up. so maybe I'm addressing two issues here. so what. how do I fix them? is it a bad pup? will getting a new audio interface help? what?
