String Identification Chart

Friendly note: You may print this information for your own use, but you may not duplicate it on your website.

We've put together this helpful information from varied sources, which include the manufacturers' websites and our own research. We hope it can help you identify what strings might be on your bass.

To use:

  • Simply scroll down the page, looking at the photos on the left.
  • If you see a silked end that appears similar to a string on your bass, stop and then compare the pegbox end description to your string. If it matches, there's a good chance you've narrowed it down.
  • Additional notes in the far right column indicate extra "rings" or features which may indicate a different gauge or other designation.

Innovation Strings

  • In 2016-2017, Innovation began to replace the "slug" end with a more conventional "ball" end (most photos are of the ball end, but some show the older "slug" ends).
  • Some of the colors changed when they went to ball ends, which is why a couple strings show two different photos.
  • Manufacture of these strings transitioned from Wales, UK to the GHS Strings facility in Michigan, USA in 2019. Colors may have changed slightly between generations due to varying materials.
