Overview

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.

Yes, I bought four of them, but I have several amplifiers.

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

In my Yamaha TC50, after trying one of these 12aY7a's in different stages I found it works well in the first stage. They bias higher ( cooler) than the X's and seem happy with this, bias voltage about x2.
This gives me more headroom and a little less low end which is exactly what I needed for the OD and no noticeable gain loss in the clean. Put one in the phase splitter and it reduced power amp bias excursions (more headroom) and lowered the overall volume just a bit.

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

I added this in the V1 slot to get a better sound with less gain in my Fender Blues Deluxe reissue. it did help, but not as much as I had hoped. i think the sound is good, but it is still very base heavey and the highs can be a bit much. next upgrade will be the speaker. i did however find that put using input 2 to plug into, that actually made a world of difference. i really love the tone and volume levels i am getting now.
