About Hi Test Guitars

Hi Test has been selling premium quality NOS/NIB tubes since 1995. We work hard to maintain the breadth and depth of our in-stock position and our website is always up to date. If we list a tube, we are in stock.

Our testing procedures are very stringent and were developed in concert with Ken Fischer of Trainwreck Circuits. Ken and Evan Aurand designed and built our power tube testing and matching equipment. We offer premium power tube matching at the same voltages that the tubes will see in your amp at no extra charge.

I have been playing guitar for over thirty years and I have extensively tubed almost every vintage amp of worth ever made. I look forward to helping you get the most from your amplifier...Gregg Levy
