The Traynor YBA-4 Bass Master is a vintage all tube combo amp known for its rugged build quality and powerful, vintage tone that is often compared to early Marshall and Fender Bassman amps. It has become a sought-after model for both bassists and guitarists due to its versatility and rich, overdriven sound when pushed. The YBA-4 is a combo version of the popular YBA-1 head, known for its "point-to-point" hand-wired construction and durable design.
