Went to see Lake Street Dive last month at the Grey Eagle in Asheville. Great show, but I'll save my praise for Bridget Kearney (and I have a LOT) for a different post. She runs her upright bass through a TubeScreamer for one song (Bobby Tanqueray), and she has (and uses) a Morley Volume Plus pedal and also a tuner on her board, along with her amp. The end of the chain is an Acoustic 212 (I think)... But I'd like to know what she's using to drive it! I snapped a terrible low-light pic--can anyone identify this micro from the back?
