OVERVIEW

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:

          it makes the amp sound so much better, it still has that distortion from 12ax7 but with more cleanroom, and the distortion sounds so much better, I changed the power tubes for some JJ 6L6 and it even sounded better

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

              This preamp tube worked well in either V1 or V2 positions (i.e. clean channel and gain channels respectively) in a Fender Hot Rod DeVille.

              It helped "tame" the amp down a bit and made the gain channel sound a bit more musical instead of the harsher sound of the 12AX7 tube.

              In other words, it warmed up the distortion channel and helped attenuate the clean channel a bit, because this tube has less gain than a 12AX7.

              Another alternative is to use a 12AU7 in these positions (i.e. V1 & V2). At the end-of-the-day, I guess it boils down to personal preference in tone and the application it's being used for.

                    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.
