Parts, Repair and Upgrades

Parts, Repair and Upgrades

If you're repairing, upgrading or otherwise modifying your bass - or maybe building a custom project - we have a variety of useful parts. Quality German-made tuning machines, real ebony fingerboards and tailpieces, steel and carbon fiber endpins, maple necks, spruce soundposts, quality bridges... even cool add-on "Kay" and "Engelhardt" logos for your tailpiece!

You might also check out our books section for some great "how-to" books on setup/repair and bass building.

Not finding what you're looking for? You can always email or call us with questions. Just because something is not on the site doesn't necessarily mean we can't get it for you.
