Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will these work on a regular bass?
No. A conventional bass threads the string through a tuner post, which needs a plain trimmed end. The second ball prevents that.
02What is a double ball end string for?
Headless basses like Steinberger designs clamp the string at the bridge and at the tuner block, so both ends need a ball.
03Can I cut these to length?
No. Cutting removes one of the ball ends, which is the whole point. Buy the set matched to your instrument's scale.
04Do I need a special tool to install them?
No. Headless systems are typically faster to restring than a headstock bass since there is no winding on a post.
