This is an Analog Man Bi-comp, which is quite rare these days. It's a compressor that combines the Ross Compressor and the Dan Armstrong Orange Squeezer 2-in-1. While there are many reissues and copies of the Ross Compressor, there seem to be fewer alternatives for the Orange Squeezer, so I think this is a recommended model for those who want to produce a fusion sound from about 50 years ago. Each can be used independently, or both can be used at the same time (noise will increase). It's a good vintage sound, the opposite of high-fidelity. It's a beautiful item that has only been used a few times indoors. It's in very good condition, so please consider it if you are looking for one. *All accessories are shown in the photos. *Please note that the bag has stains due to aging. Due to concerns such as preventing product substitution, we cannot accept claims or returns after purchase, so please consider purchasing only if you agree to this. I think it's a very beautiful item, but it is used, so please refrain from purchasing if you are sensitive to this. Thank you.
