New string day! Been using GHS Pressure Wounds strings on my ‘72 Jazz. Really like them, have them also on my P-Bass and Fender PJ Boxer bass. But wanted to try something different. So got me some Rotosound Solo Bass 55 Pressure Wound strings. First impressions is good. These are a tad heavier then the GHS which I like. The GHS set is 44-58-80-102. The Rotosound set is 45-65-85-105. I love the Rotosound Jazz 77 Flat Wound strings which is why I am trying these. The tension feels a bit less then the GHS and they feel good playing them. They are a bit rougher feeling then the GHS, but not by much. Probably due to these are Stainless and the GHS are nickel. Through my practice amp they sound punchy and nice mids. The true test will be through my main rig at a gig. But so far, I like them!
