This is the TRBX504 bass from Yamaha, an affordable but super versatile and great looking 4-string bass with a transparent white finish over a solid mahogany body, a 5 piece maple/mahogany neck, active/passive electronics driving a pair of alnico V humbuckers, a 1.5" nut width, and a high-mass die-cast bridge for sustain and solid intonation.
