I have a used personus ACP-88 for sale. It is an 8 channel gate, limiter, and compressor. It is used and an excellent shape and working condition. There is a little rack rask around the screw a couple of the screw hole. But, once installed in rack, the rash is invisible. Would like to get $500. I will cover the shipping anywhere in the lower 48. Email me at email@example.com, or call me at 815-621-8718. Thanks.
