Been rolling tubes in my Terror Bass head and this is the only one valuable enough to resell. Bought from Tube Depot and used a total of maybe 5 -6 hours. Is in excellent shape. A well made American tube for sure. Goes for $60 plus shipping from tube depot. Here is their blurb about it... "The JAN GE 12AX7 is a great sounding tube for both Hi-Fi and musical instruments. Many guitarist love this tube for its warm but crisp tone. These are some of the last USA made 12AX7 available. They are just becoming harder and harder to find. Get a set for your system and see how US made tubes can make your rig sound better. " Yours for [DEL]$40[/DEL] $30 shipped CONUS.
