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.
