So when practicing my amp sometimes loses the gain stage and the volume backs down a bit, almost as if I am playing on a clean setting. This happens sometimes after taking the amp out of standby and last night it happened when in the middle of playing. After a bit things go back to normal. The tubes seem ok and are all about a year and a half old (all JJ's), so what could be the problem????
Year and a half is plenty of time for tubes to begin wearing out.
Tastes like chicken, if chicken was a candy.
