Pressurewounds strike the perfect balance between aggressive and smooth, with less finger noise. Wound over a hex core wire, a highly magnetic nickel-iron alloy (Alloy 52™) is run through precision rollers, slightly flattening the final wrap. The result is a string with incredible articulation that can run the gamut from motown to progressive and back. Fretless players also love how Pressurewounds retain that signature "mwah" tone, while going easy on their fingerboards.
