    Recently my amp is sounding very subdued in the treble/high end (sort of like it has a head cold). I find myself with the treble maxed on the bass and higher than normal on the head. I spent quite a bit of time with trying different settings on the amp and basses but still, the same result. Normally I don't touch the treble on the amp or bass (my active ones at least). I'm usually tweaking the mids if anything. However even the tone of the beefy mids that I love seems to be lacking. I'm wondering if the tubes are aging and losing ht the top end; but given I don't know much of anything about tubes, I could be way off here.
    I did have to replace one back in September (completely different issue; much more drastic) and am now wondering if the others are due.

    It's possible that either the v2 or v3 tube is bad. Try replacing with a known good tube one at a time. Be sure the amp is disconnected from the power source before doing anything inside your amp.

    All better. Just replaced both v2 and v3 with Mesa tubes actually. It's now back to the amp I love :)
    Thanks again.
