I just set it as flat as I can get it for a clean sound...bass at 12:30, mids and character slightly past noon, treble at 10:00, and as I increase drive, I add a little bass to correspond with the clean sound. JohnK and a few others did the hard work and I just copied what they didJimmy - you've got to compile and re-post your series of obsessive/compulsive VT Bass setting posts from like 10 years ago. That'll teach 'em.
