I just tried them for the first time for my down tuned Jazz Bass. I was told they don't have a lot of tope end and lots of mids, which is what I want for my J. They certainly match the description. The first 3 strings are ok but the low C (.126) sounds like garbage. Really thuddy and dead. This is the last set of GHS strings I ever buy. I have tried Boomer, Brite Flats, Flats, Pressure Wounds. They all either sounded like crap or wouldn't intonate.
The La Bella Nickels are really bright, kind of boxy sounding. not sure what kind of tone you are looking for but they are pretty bright for nickels.
I am having a real hard time finding strings from my J. I like the Nickel Lo-Riders but they dont come in the gauge I need for the low tuning. Any suggestions for a warm nickel plated string that comes in a .125, .95, .70, .50? Doesn't have to come a set as long as I can buy them as singles. I'm willing to try darker sounding SS too if I have to. Tried La Bella, D'addario and Boomers so far.
