Ok so yesterday I was playing and all of a sudden it sounded like as if my amp had a dying battery. So I turned it off and tried playing it again moments later and it works fine but lost quite a bit of gain (not volume).

I bought the amp a week ago

amp: mesa boogie mini rec


Thank you!

PS. I wasn't running through any effects... also I'm not sure whether this could by my guitar pot problem because it crackles and hums.

Sounds like a tube problem! Swap them out and see if that helps it?

Gain drop = pre-amp tube problem usually. If it was a volume drop problem, that would be the power tubes at fault. Hope this helps.

Ya i was guessing it was one of the preamp tubes .. but is it more likely to be the v1 or the other ones for this ?

Saw the same thing happen in a brand new Mesa Lonestar. Phase Inverter tube became leaky and caused loss of volume, except for a very faint amount. Try some tube swapping. Chances are, there's one tube you can get by without, such as an effects loop tube. Unless you have spares.
