It's a new day for all bass players. You can now create your very own nickel wound custom gauged bass guitar string sets that will give you that perfectly balanced tension you have always wanted for the unique way that you play. There's no right or wrong here. You decide what works for you! We are able to offer you this service and the huge range of string choices because Curt Mangan makes his own strings right here in Cortez, Colorado and all wire is USA made. Have fun! If you have any questions just ask Curt. So just select the custom gauges you want from the drop-down menu, select either 4-String, 5-String or 6-string bass guitar set, type in the name you want on the label and upload an image. This is a great birthday or Christmas present for that special guitar player in your life! All Curt Mangan Strings are packaged in sealed anti-corrosion pouches.
