My main axe is a Ric 4003. After trying the usual suspects way back when, I decided on DR FatBeams (ss rounds). They'vey been my string of choice for a few years now. A while back I read about suggestions for Ric strings and GHS Progessives was mentioned. I was long overdue to replace my FatBeams, so I ordered a set of both the GHS and the DRs from bassstringsonline.com. Price on the GHS Progressives was very affordable, and I have them on right now. I'll play 'em for a while and see how my band mates like them. To me, they are pretty good. Not quite as grunty/grindy as the FatBeams, but otherwise a nice string for me. And for the Roto 66 fans, I did try them a while back. On my Ric, there's nothing like them. Tops in my book. But they die too quick for my budget.
