i've had my variax 600 for over 15 years, and i'm so happy with it, i bought a used one as a backup for gigs. it sounds generally the same, or very close, as you would expect. but the "new" guitar seems to have lower output. even at full volume, it's clean, clean, clean. it doesn't push the amp the same way as my original 600. is that something i could do something about, maybe in workbench? thanks.
