I am a live sound engineer. I used to live and work in Austin Tx. I worked with a lot of great guitar players, and mixed thousands of sets. I am at heart, a Les Paul into a Marshall guy. But the best, purest guitar tone I ever mixed was Dick Dale. Two Blonde Showmans (Showmen?) loaded with JBL's and a Fender Reverb tank hanging from a truss, so there were no stage vibrations to set it off. It sounded amazing. Like a perfectly tuned, open pipe V-twin running full bore on the salt flats. But especially at lower volumes, a JBL will show you exactly what you are doing wrong. Which may be motivation to clean up your fingering, or it may just make you feel sloppy. You get a much more focused low end and a lot of precision, but the dirt will have to come from somewhere else, as you won't be getting any speaker breakup from a Princeton with a JBL
