Early 70's vintage gain levels with a returned wider frequency response.

The Groove Tubes GT-12AY7 Select Preamp Tube is closest in specification to a 12AX7 and can be exchanged with a slight drop in gain. Most companies changed over to the 12AX7 as it became more common.

This tube can be tried in later Marshall amplifiers in the first gain position, where the owner of these amps would like to drop the background noise and lower the gain level to plexi or early 70's vintage gain levels with its returned wider frequency response.

        Comments about Groove Tubes GT-12AY7 Select Preamp Tube:

        AY7 tubes have about 30-40% less gain than the usual AX7 tubes which makes then really useful in the first tube position (V1) for taming a gainy, noisy amp and/or increasing the headroom. The tube will allow you to decrease the gain, give you more sweep on the tne controls, and give you more output tube volume and distortion when pushed.
        This GT tube is fair priced and does that.
