The Traynor Custom Special YBA-3B is the final production revision of Yorkville Sound's British-voiced 50-watt guitar head, reflecting the most refined iteration of the YBA-3 circuit before the model was eventually superseded. It preserved the fundamental architecture — EL34 output stage, multi-input two-channel layout, and the characteristic Traynor midrange voice — while incorporating the accumulated engineering refinements of the model's production history. The YBA-3B is considered by collectors to be among the most consistent-sounding examples of the Custom Special line.
