Got it! Here's what the issue was/is with the AD100VT. With the 212 configuration, the bottom end (bass) is pretty powerful with the master above 12:00. If I cranked the mids on the amp while running the master at 3:00, lead tones would be heavy on the midrange due to the tube distortion and produce some muddy bass. What I did tonight was set the tone on the amp with the master below or at 12:00 and that added some top end . Also, adding some compression to the lead tones also evened out the bass and the treble when using the neck pup and bridge pup respectively. I was able to dial in a sweet Boutique OD lead tone that had some top end shimmer, smooth mids, and a tighter bass. Didn't have to tweak the guitar tone knob as much on the bridge settings.
