I has been a long known "secret" of producers and great guitar players that mixing in a bit of clean, direct or acoustic guitar to a distorted guitar part adds richness and clarity, even in miniscule amounts, slowly those secrets are trickling down and are becoming more possible to incorporate.Additional note: Dr. Wattson X is smooooooooth on guitar.
I hope you'll excuse me patting myself on the back, but it turns out everything that sounds good for bass also sounds good for guitar.
