[Wooly]

I have this new LR Baggs M1 passive which isn't a real hot pickup. I have been running it through a Behringer ADI21 into the mic input on my Loudbox Mini. (We're talking just for home use here.) I am getting a very nice sound and A LOT of volume. Compared to plugging it into the regular guitar channel with the ADI21, I get a nice sound also, maybe a little better, but not near the volume. I have to turn everything up a lot. Why would that be and is it OK to put it through the mic channel?

I have noticed also that in the guitar channel, The A string starts vibrating and feeding back until I hit the phase switch on the amp. Maybe my strings are too close to the pole? I didn't think that a phase switch would matter with a magnetic pickup?

Enlighten me please.
