Up for sale is a Shaw Tube Injection. I purchased this used from another TB member a year or so ago. Hate to sell it but medical bills are a priority now. I have used this on all my electric bass gigs for awhile now. No issues with the unit whatsoever. I have used it to send a signal to the FOH engineer and he loved it. I was in the studio last May and their B15 was acting up. So I tracked my 1964 Newport and my Precision with this. Engineer loved it. Oh, the tubes. All of the tubes came from the previous owner. The one in the Shaw is from May of 1945 as per the label taped to the unit. A duplicate of that tube will be included as well as two 1968 RCA tubes. I used a Harbour Freight case for the unit and it will be included. No Velcro on the bottom, just some self stick feet so it doesn’t slide around on a bass cab or desk. Shipping is included to the lower 48/continental USA. PayPal only.
