Howdy! I might be interested in moving my Aerco MP2 to a new home. It's just not getting the action that it should. It went back to Jerry about 6 months ago to have new batteries installed and fix the battery wiring.
Let me know if you are interested and I can text you some pics and give details. It has most of the usual options - internal rechargeable batts, XLR in, RCA and mini out, stepped gain on one knob in 10dB steps, stepped trim on the other in 2dB steps, on off switch on the back and a DC input on the side plus the DIN connector for charging the batts. Includes the gigantic battery recharger dealio.
I paid $500 and spent another $100+ on batteries and shipping it to Jerry. I'd let it go for $525 shipped. Gotta put a new exhaust on my truck...
