GHS Pressurewound bass strings effectively split the difference between traditional flatwound and roundwound strings, giving you loads of articulation without excess drag or string noise. Here's how it works: GHS subjects its nickel-iron Alloy 52 Pressurewound wrap to a high-pressure rolling winding process to slightly flatten the final product. This gives each set of strings a brightness you won't find in traditional flats, as well as a smoothness and squeak reduction you don't find in fresh rounds. GHS Pressurewound bass strings feature a hexagonal core to further maximize brightness and attack, all while giving you a silky-smooth response under the fingers. It's truly the best of both worlds. If you're looking for a set of bass strings that bridges the gap between traditional rounds and flats, bassists at String Swap highly recommend GHS Pressurewound rollerwound bass strings.
