Upright Bass Bridge Adjuster Wheels
1/4"x20 Black Aluminum most common size
Mailing cost is $5 for any number of sets.
These Bass bridge Adjuster wheels are a great substitute for the Wheels of a Fishman Pickup, in case you have a different pickup you want to try. You can take out the Fishman and put these adjusters in.
This is the most common size of adjusters in adjustable bridges where the threads screw into the wood.
These will NOT fit into brass adjuster inserts in a bridge. If you have brass looking adjusters, take the bridge apart to see if the adjuster fits into a brass sleeve. If so you need that kind of adjuster which we can supply, not this aluminum kind.
