This is a late 90's Tube Tech CL 1B that I've owned since 2001. I used it in my travel rack for tracking bass at studios outside of my own. It was never used daily or even weekly, and has relatively few hours on it for its age. It has normal rack ear wear and a couple of little other minor scuffs but otherwise functions and sounds like new. I've included a picture of the inside so that you can verify that it is indeed a genuine early era Tube Tech and not counterfeit.
