Up for sale is my Markbass (tube) Compressore. This compressor plays like butter. Na, just kidding, but it is a very smooth compressor. Includes shipping CONUS. Per Bongo's ovnilab.com Markbass Compressore review - "this comp is pure gold. I would put it up against a high-end rack unit any day" The tube has been replaced once in its lifetime, in the last year, so should be good to go for a long time. I am the original owner. The tubes are $20-$30, and available at your local Guitar Center. Includes original power supply and velcro on the bottom. Markbass Compressore by tedsalt posted Mar 16, 2018 at 10:27 AM
