    I've just started noticing a significant loss of bass from my Matchless Avalon 30, and I have no idea what's causing it.

    Thoughts?

    Yes sounds like a bad power tube

    In my experience, when an amp starts sounding dull or somehow off, I replace the power tubes. Particularly if they are over a year old.

    Awesome. Thanks guys!

    I usually run the master volume WIDE open, so it makes sense the power tubes would take a beating. ;)

    I've actually been experiencing the same with my Fuchs lately, but figured mine was preamp related since I rarely have my master above 2. Tone is thin even with the bass cranked, OD is brittle and weak. Fortunately I have a spare set of 6L6s to try, but I'm gonna have to wait to get paid before I can get new 12ax7s...
