New for 2014, GHS is proud to introduce the Crossovers, strings designed for any bass made to the NS EUB standard, including our own NXT and CR Series of Electric Upright Basses. Nickel-Iron Alloy 52 is wound over a round core wire and then micro-ground for a smooth, upright bass feel. GHS explains that this yields a string with a deep and focused fundamental tone, suitable for those needing both contemporary and traditional sounds.
