The GTECC83S preamp tube passes every Groove Tubes premium certification for microphonics, hum, physical characteristics and function. Quite simply the best 9-pin triode preamp tubes you can buy — specifically designed and tested for musical instrument amplification and standard equipment on Fender® amps. Outstanding and consistent performance for mixing and matching to get a signature tone from your amp.
Our highest-gain preamp tube, this tube has a huge amount of gain, with terrific output that makes it a great choice for driving modern, complex high-gain circuits. It has a relatively high quality variance (making Groove Tubes pre-testing procedures especially important in this case), with a tight, strong and relatively bright tone that can really liven up a weak or tired old vintage amp or a new amp with grade-quality tubes.
