I've been using a combination of the audio technica soundhole mic (the better one with the flatter frequency response -- i forget the model) and a bigtone pickup. I mix it so the bigtone is giving the bulk of the mid to low end and use just little of the mic to brighten up the sound. All this gets run through an AER compact 60. The sound is acceptable, but the attack can be a bit harsh and I think some compression to squash the heavy attacks would even out the sound a bit. Since I use the AER piezo input to preamp the bigtone, I can't use a stompbox compressor such as the MXR dynacomp to do the job. Also, since the mxr is designed more for electric it tends to cut a lot of the high end and the compression is a little too intense even on the lowest setting. I'd like to find something that works at line-level that I could use in the effects send of the AER. I'd also prefer something small (like a stomp box) that will be easy to pack in my gig bag. But the standard electric guitar stomp boxes don't seem to be compatible for a line-level send. Does anyone have a suggestion that has worked for them?
