When I last played through my 3-channel Dual Rectifier, it was with a Strat. Sounded great. That was a few years ago. That guitar was stolen a few months back, and now I'm down to a single SG. I plugged it in the other day, and there's almost no high end at all. Very, very dark. Same for all three channels. On the clean channel, if I crank up the treble and presence and cut the bass a bit, it sounds okay. But should I have to do that? (never used this guitar with this amp before)
Mesa told me it sounded like worn power tubes. I replaced the original four 6L6's with a single pair of new EL34's (and pulled a rectifier tube, as instructed in the manual) wanting to try the half-power mode. The guitar doesn't sound any brighter than with the old 6L6's.
Before replacing the power tubes I ran a line from the SEND to my Boss GT-10 and listened on headphones (wanted to rule out the preamp as the culprit). It sounded nice 'n' bright even with flat EQ settings.
But even new tubes didn't bring that brightness through the speaker cab (4x12 slant).
Should an SG sound that dark? My Strat sure didn't.
I'm in Tucson. Could the arid conditions here have dried out some power amp caps over the last seven years that could be rolling off all this high end?
I'm out of ideas... :?
