Yup, I couldn't wait to show my band what a great new amp I have, and right out of the gate the volume dropped and the amp sounded like it was farting. I opened up the back (no easy thing - what idiot designed the stupid cage for the power tubes that gets in the way and hides the preamp tubes as well?).
I had spare 6L6s with me, but that didn't help. It was all modes, so I figured PI, or FX return. BUT, no 12AX7 in my bag. DOH! Plus, I did not have a tube chart with me, so I didn't know which was which (though I would have guessed the PI was the one not in a pattern with the others). ANyway, I reseted them all, and got enough volume to get through practice, but the tone was awful.
Just got home and replaced V7 (PI), and IT'S ALIVE. ****, wish I had retubed like I usually do with a used amp. But it's so new (it was purchased new only 10 months ago), I thought the preamp tubes would be fine.
