More Power, Longer Life, and Better Tone from Groove Tubes!

Note: all of the Groove Tubes tubes and sets we carry are "Mediums," or in the 4 to 7 range. Tubes are non-returnable.

Groove Tubes has been manufacturing, importing, and grading quality power tubes for two decades. No stranger to Sweetwater, 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 equipment, and true tube aficianados worldwide swear by the tubes and pro audio products Groove Tubes makes. For premium tube tone, choose Groove Tubes!

The GT-E34LS Power Tubes Duet features an exclusive Groove Tubes design with special "heat wings" attached to the plate for more power, longer life, and better tone. This E34 provides a big bottom, and it's very dynamic in addition to being the most powerful tube in its class. The GT-E34LS has an exclusive specially modified power pentode with 15 percent more power and great overall tone. Big heat sinks attached to the plates keep this one from "sagging" at full power, keeping the bass tight and treble crisp. It's the choice of legends such as Billy Gibbons, Joe Perry, and Joe Walsh. This is the group of two, also sold in groups of four.
