This is the preamp for the Dyn B microphone for acoustic bass, but it’s similar to other acoustic instrument preamps on the market that are used to EQ and tame resident feedback. It has been upgraded from 12 V to 24 V power supply (adapter included). The included documentation states that it was originally intended to have this supply.
For the adventurous, I will also include the Dyn B mic itself. Unfortunately the mic element is loose and rattles at certain angles. Repairing it isn’t in my skill set but maybe it’s in yours. Postage will probably go up a little bit if you’d like the mic included.
