Tube Fender Groove Tubes GT 12AX7-R Slightly lower gain, quicker compression than GT 12AX7-R. Great for most Fenders, may not be well suited for high gain Fender type amps (such as Boogie). |
Great warm clean tones, strong bass, punchy mids and fat overdrive with smooth top end.
No Microphony, No Hum - Clean Warm Tone, Punchy Mids, Fat Overdrive!
All preamp tubes labeled Premium Selected have passed the following tests:
- Low Noise Test
- Microphonic Test
- Gain Test
- Sonic Tests
- Shock Tests
- Listening Tests
- Balanced Output Test
HIGHGRADE SELECTION
But only those tubes which pass these tests best are labeled Highgrades.
Matching and Selecting Options for Preamp Tubes
Matching in Pairs for preamp tubes means that two tubes show identical gain, hence, four characteristically identical systems.
This matching method includes our Balance-Selection. We highly recommend this matching method for hi-fi systems.

Selected ECC83 for the big & warm clean sounds (great for HiFi too!) and mellow top-end when pushed to overdrive. Our recommendation if you want to emphasize punchy mids. Especially great when pushed into a fat overdrive.
All preamp tubes labeled Premium Selected have passed the following tests:
- Low Noise Test

Premium Selected
We call the tubes SELECTED which have passed above tests and thus qualify as reliable all-round tubes of their type.Typically this is around 30-60% from a batch that receives the SELECTED label from TAD.
For applications in particularly sensitive functions such as V1 or input stage with combo amps, V1 in high-gain amps, tube microphones and phono preamps, we recommend using the respective HIGHGRADE selection
