The TAD 6V6GT-STR is a heavy duty 6V6GT tube, which can handle a higher plate current. It works great in Tweed 5E3 Deluxe and Deluxe Reverb Amps. Even when pushed into saturation there are no harsh upper mids, which is frequently the case with other 6V6’s. The TAD 6V6GT-STR always remains detailed and has a powerful tone and an abundance of sustain. Sweet full-bodied tone with silky highs.
