Re: What brand and thickness picks do you use?
I've gone through dozens of different picks over the years, including a brief fling with genuine tortoishell... (expensive!). Presently, I use the .88 mm Dunlop nylon jobs. They last a long time, are readily available, and sound good for the type of picking I do.
When I was working on jazzy leads and such, I did like the little, thick Dunlop jazz picks.
