For sale: my gorgeous Yamaha RBX6JM in very good condition. The narrow string spacing makes this neck really comfy for non-six-string players. This particular one has had the lacklustre stock Yamaha preamp upgraded to a much better Schack 3-band pre that makes it a surprisingly versatile instrument - have just been transcribing some Abraham Laboriel fingerstyle gospel lines with it today and wondering if I really should be selling it! Gold hardware (some mild tarnishing as expected), ebony
