I've really been liking Don's tone lately as I've been watching lots of him and Bucks videos. the tone is so clean. It sounds a lot like my 67 Pro Reverb but even cleaner and shimmery. It sounds like my amp when I play it completely dry from effects except some amp reverb. But his playing sounds almost staccato at times or maybe even I hate to say a bit sloppy for lack of a better work. Even though I don't think his playing is sloppy. Could his tone have been improved a bit with some compression and made the playing a bit smoother or would that have just wrecked it. I assume thats a Fender Twin he's playing through. In this video you can hear Don's playing is crystal clean and the steel player has a good amount of distortion.
