This new TAD 12AY7 HIGHGRADE is selected to be the perfect choice for the first stage of any modern high-gain amplifier, delivering a true and warm tone while remaining quite open with defined punch in the lower mids. The highs are smooth but well defined and detailed; your tone will always stay focused. Dynamic attack is met with tonal depth and responsiveness. With less gain than a 12AX7, the TAD 12AY7 HIGHGRADE adds a tad of vintage touch and feel to your tone with more headroom and a significantly wider sweet spot which gives you more control over your tone.
