Can anyone hip me to any inexpensive (but good sounding) battery powered preamps? I have this perverse desire to take one, a mic, my line 6 DL-4 and a Hognose amp down to our mall and do some guerilla loop performances. I have a line on a Shure PF-11 which lists for $377 and which has been offered to me for $199.........what do you guys think? yours, Rick Walker (loop.pool)
