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 toys, and true tube aficianados worldwide swear by the tubes and pro audio products Groove Tubes makes. For premium tube tone, go with Groove Tubes!
Based on a tube which is considered an icon to EL34 users in both the audio world and guitar amp world, the GT-EL34M Power Tubes Quartet gives vintage tonality. The original was a vintage, and now the GT-EL34M is on its way to developing its own killer track record just as the GT-6L6GE, E34LS, and KT88SV proprietary tubes have. This tube is available in matched quads.
