Ranney is a small-scale custom bass guitar operation run by luthier Eric Ranney, best known for building 8-string basses. Ranney's instruments are designed to allow each of the eight strings to be intonated individually — a key distinction from factory-built 8-strings where the octave-paired strings share a single saddle — making them a favored choice for players who want precise intonation across octave and fifth string pairings.

The most widely recognized Ranney instrument is the 8-string bass built for Chris Squire of Yes, which the bassist adopted after his original Rickenbacker 4008 became difficult to keep playable. Ranney's output is low-volume and built to order rather than produced as a catalog line, and the brand has a cult following among 8-string bass enthusiasts and progressive rock players.

Ranney has 2 products cataloged on Equipboard, including Electric Basses and DJ Mixers. Their gear is featured by 1 artist, with the strongest followings in Rock. Notable users include Chris Squire.
