Tube Amp Doctor - 6V6GT-STR Premium - Power Tubes
You Save: $10.00
Sweet full-bodied tone with silky highs
Finally in production after 3 years of intensive research.
This all new TAD 6V6GT-STR combines the exceptionally sweet characteristics of the NOS 6V6GT by RCA or of the GE 6V6GTY. It is a heavy duty 6V6GT tube, which can handle a higher plate current.
This TAD 6V6GT-STR caters for a detailed and powerful tone and an abundance of sustain; characteristics you would only expect from the finest NOS 6V6GTs from the 50s and 60s. Even when pushed into saturation there are no harsh upper mids, which is frequently the case with other 6V6s. Sweet full-bodied tone with silky highs.
We recommend the TAD 6V6GT-STR for all 6V6 applications where a powerful but sweet tone is desired; It works great in amps like the Fender -Tweed- Champs, Deluxe Reverb Amps, Vibro-Champ, Fender Champion 600 or the Univalve. This is also the perfect choice as a reverb driver for the Vibrokings and Dual Professionals.
