Do you know your La Bella string types? I've got a Stienberger siprit xt 2 bass which I think ( according to musicyo.com) is fitted with "Official Steinberger USA strings are hand-made by the world-famous, La Bella string company of Newburgh, NY and represent the absolute BEST sounding and BEST performing strings available. Made of the finest materials and perfectly calibrated to work with your Steinberger Double-Ball tuning system, you will immediately feel and hear the difference. Treat your Steinberger or Spirit by Steinberger to the BEST strings money can buy! Gauges are: 040-060-075-095 Specifications: 4-String, Stainless Steel, Light, Round Wound" Does anyone know what model/part number these strings are called when offered for a conventional bass- i.e. not double ball ended. Any help appreciated.
