A dual input preamp with a stereo out, the A2 has a direct frequency response and 21dB of gain. The electronics are mounted in a very small box directly coupled with a high quality end pin jack for easy mounting. B-Band UST under saddle pickup (specify narrow or wide) and AST soundboard transducer both plug into the preamp and provide balanced tone together. Stereo out lets you separate and or mix the signals with your amp. UST channel has a unique contour filter for upper register tone enhancement. High frequency enhancer switch gives a mild boost to the highs or leaves the signal flat.Second channel will, if preferred, accept a soundhole condenser microphone or magnetic pickup as an alternative to the AST. DIL-switches to: turn on bias voltage for the mic, turn on a highpass filter for microphone feedback reduction, and lower the gain from 24dB down to 0dB.Comes with mounting hardware, 9-volt battery clip, and wire harness.The B-Band UST (under-saddle transducer) still stands as the first transducer that sounds better alone than many pickup/microphone combinations. Designated the "4th Gen UST," this latest UST has been stiffened for better string balance qualities, higher output, greater durability, and lower background noise. Since it is only 0.4mm thick, it usually does not require a new string saddle or adjustment to the saddle cavity. The UST is a flexible, rugged, and constant structure all the way...
