I've been playing Fender flats on my G&L L-2500 exclusively for a couple years now. Here's what I love about them: Super-strong fundamental Medium-high tension Plenty of highs, for a flat Very little string noise I've been playing Jamerson-style soul and they are about perfect for that setting. However, that group is wrapping up, and I'm interested in trying some rounds again. Here's what I'd like (and don't get from the Fenders): Clear, articulate B-string (Fender is all thump) More expressive, dynamic attack on higher strings for solo playing More detailed sustain I want a complex-sounding round that "speaks", but still has some of that deep, smooth flat fundamental. I've been looking at: DR Lo-Riders Ken Smith Compressors Sadowsky Blue Nickels GHS Pressurewounds (tried these a while back but wasn't real impressed) D'Addario EXP Nickel FWIW - these strings are for a modern electric-jazz type sound. Not a slapper, not a rock/metal player. Stainless steel is probably too bright for me.
