Here's the situation: practice at lunch via my crummy headphone amp with my G&L L2000 (neck pup, passive, series) and love the tone (as usual). After work head to practice. Before everyone else starts up the tone is great. Everyone else (guitarist w/Les Paul and Marshall half-stack, drummer on electronic drums and singer via PA) arrives and the tone is not cutting it in that situation (although it has in the past with the full band which includes another guitarist with half-stack). Pop the L2000 over to active to get more bite and adjust vol/treb/bass to my liking. Love the tone. After a few songs I'm having trouble hearing myself other than as a dull boom. Move to both pickups in parallel and adjust vol/treb/bass. Tone is good enough (don't love it anymore). Near the end of practice it's either booming or not audible again. We weren't way loud (there are times I leave the room because it's too loud) but the drummer seems to always creep up in volume and the guitar player, well, you've all heard about guitar players. But since it was only one guitarist this week it wasn't as bad. So I think it was a combination of "ear fatigue" from the volume and maybe a cold coming on throwing my ear off. But it's a pain to go from "love the tone" to having to adjust it just because I can't hear it anymore when at other times when the volume stays down I don't have to touch a thing for the whole practice and love the tone at the end as much as at the beginning. Oh well, got to go back to being the volume nazi, I guess. Maybe I need a bigger amp, too. My 135W 1x12 w/tweeter is loud enough but greater overhead may make things better. Anyone else run into the same thing?
