His sound is one that depends much more on how he plays, than one what he plays through, I think. Clean is clean, for the most part. I would have limited that to tube amp profiles, but BB King went from Fenders to Lab Series, and it still sounded just like him
I agree completelly Paults . But i read his Le chic guitar sound on record, was recorded straight to desk SSL or NEVE ( i dont recall) with compression , if i would record i would try that, but for live sound there are so many good clean profiles . And mats posted some really sweet replicas profiles !
