TRB and TRBX are a series of bass guitars designed and produced by Yamaha. TRB originally launched in the early 90s as a versatile 6-string model but later has expanded into a full range of 5-string and 4-string models, while TRBX lineup features the same body geometry and a slightly shorter 34" scale length and serves as a replacement for now discontinued RBX and TRB series.
For convenience's sake this tag acts as an umbrella tag for both TRB/TRBX and RBX lines of bass guitars due to their visual similarity.
