A compressor with a silver metal casing and four control knobs. I bought it used a few years ago and used it for production about 4-5 times. I am selling it now because I purchased a new replacement. The smooth compression is exquisite, and I felt it lived up to its reputation as a classic. The "super nice" mode was particularly good, and I used to love it so much that I would press that button just to see the response. I hope the next owner will also use it to compress a lot of audio. ★ Power supply included. ★ Item and power supply only. Please note that there is no box or manual. ★ Power-on has been confirmed.
