The all-new designed TAD 12AX7 / ECC83 Redbase is a miniature, high-mu twin triode with very good gain. These tubes are selected and recommended for guitar amps to improve overall responsiveness and dynamics. Because of its cathode-to-heater voltage-withstand capability, this tube works perfectly as a cathode follower. Best for thick, clean tones as well as for those modern preamps where a deep low end is required as well as for sounds requiring fat midrange, detailed airy top end and lots of power from the preamp. Recommended for all positions in medium gain amps or for V2+ positions in high-gain amps. For V1 in general but especially for high-gain amps or phono/audio-amps, we recommend the new 7025 / E83CC Redbase Highgrade T-7025-RB-TAD.

The result is a tone that works well in both modern amps but also vintage guitar amplifiers. If the ECC83-WA is used in hi-fi audio amplifiers, the tube adds a musical clarity and presence to the signal. The new TAD™ ECC83-WA is a miniature, high-mu twin triode, selected and recommended for guitar amps to improve overall responsiveness and dynamics. Great for guitar clean tones with a distinct pick attack and pronounced upper mids to cut through every mix.
