amplification and standard equipment on Fender amps. Outstanding
and consistent performance for mixing and matching to get a
signature tone from your amp. The highest-gain output tube in the

output, but with a shorter plate, higher gain, and a more
consistent quality variance score. An extremely consistent tube
useful in most applications.
