Hi. I'm looking to sell my Presonus BlueTube mic pre. I just bought a new board so I'm getting rid of a few of my outboard pres. I've had no problems with it. The previous owner said that he could occasionally hear some scratching when the knobs were turned, but I never heard it, but just so you know... Looking to get $50 shipped. Comes with power cable & manual. Shoot me a message with any questions or if you'd like more pictures, thanks!
