Conspicuous by their absence in amplifier discussions for Gypsy style jazz and their guitars are the other acoustic amp makers. Specifically Trace Elliot and SWR California series amps. Are they not good for this style? Too big? I've seen photos of Gypsy players with Trace Elliots and I know Jorgensen used to use a California Blonde (though unclear if it was for GJ). What are the Cons and Pros for anyone that has experience with these. I also see more players using the Roland AC-60 any comments on these (besides being relatively inexpensive)?
