GearNuts Essentials Make Your Axe Rock!

Just so you know: the Groove Tubes tubes and sets we sell are all "Mediums." That's in the 4 to 7 range on Groove Tubes' scale. Sorry, we cannot take returns on tubes.

Groove Tubes has been manufacturing, importing, and grading quality power tubes for two decades. No stranger to GearNuts, Groove Tubes founder and energy source Aspen Pittman has paid us numerous informative (and always entertaining) visits through the years. His tireless pursuit of perfect tube tone has resulted in Groove Tubes' reputation for consistency and premium quality. Want proof? Fender tube amps now include Groove Tubes as standard gear, and true tube aficianados worldwide swear by the tubes and pro audio products Groove Tubes makes. For premium tube tone, go with Groove Tubes!

The GT-6L6CHP Power Tubes Quartet features a Groove Tubes exclusive design. These tubes are high-performance 6L6 Black Plate models with heat sink wings (similar to the GT E34LS and KT88SV).   The GT-6L6CHP Power Tubes Quartet sports a totally bulletproof, smooth, and linear tone, and they sound fantastic in Fender Hot Rod Deluxe and Deville amps. These 30 watt tubes are available in groups of four.
