Description
6550R Medium Duet - Groove Tube's highest-output 6550 is slightly easier to push into distortion than the original G.E.® version and has a harder response than the “C” for tighter, quicker response. Good for bass amps and metal, when more pronounced note definition is desired with just a touch of distortion.

For over 30 years, Groove Tubes have been trusted and demanded by touring professionals and their techs around the world. Groove Tubes started in southern California, and through innovative design, rigorous selection and testing, GT-powered amps have rocked the world in some of the most famous rigs ever played from studio to stage. Combining our passion for music with the science of sound, the Groove Tubes team still employs the same testing, grading and matching disciplines that continue to deliver flawless performance every time.
