Fender GT6550 TubeFender tube amps now come factory equipped with matched Groove tubes. Because they are color coded and matched, no re-biasing is needed. You simply match the red, blue or white color coding when replacing them. They give you better harmonic balance, longer life, matched gain to distortion ratio, plus a wider frequency response than any other tubes available.
