Jeff Mattson's tone,
I saw Jeff with the Donna Jean Band at the Bearsville Theater in Woodstock.
Looked like Jeff was playing a stockish strat into a tube amp that I did not recognize.
Needless to say, Jeff got awesome tones, apparently no pedals, no buffer, no Super IIs, no twins and possibly no JBLs either! Yet despite all of this lack of gear, Jeff emulates Jerry as well as, if not better than pretty much anyone. GO figure! Go Jeff.
Of course we joke that Jerry played Sugeree maybe 3000 times, while Jeff has played it 10,000 times!
