Adds Clean Headroom
I used this in my Marshall SV20 Plexi to get a little more clean headroom. These amps have fantastic clean/edge of break-up tones but they do start to break up pretty early. Putting this tube in V1 instead of the 12ax7 extends the cleans a bit, and still leaves plenty of gain on tap for that classic Marshall Plexi drive.
Good tube
I bought this for my Vox AC10 because they have a reputation for containing cheaper Chinese tubes and the existing 12AX7s broke up a little too early for me. I wanted to get a bit more clean(ish) headroom and a richer tone. These did the trick.
Great tube for taming volume
Tesla makes great tubes and this one is no exception. I bought this tube to replace the 12AX7 in my Fender Hot Rod Deluxe and it works great. My one gripe with the Hot Rod Series is the volume jump between 0 and 1 - using a lower gain preamp tube like the 12AT7 reduces the gain and thereby the volume of the amp overall. Still gets super loud, just much better tone at lower volumes.
