Yamaha has announced the new TRBX series basses, which update classic models with new EQ systems — and the new instruments are already in stock at Sweetwater! There are four models in the new family: the four-string TRBX304 and TRBX504, and the five-string TRBX305 and TRBX505. All TRBX basses feature five-piece maple/mahogany necks and mahogany bodies. The 300-series instruments feature two adjustable EQ bands plus a Performance EQ switch, with five preset EQ curves including Slap, Pick, Flat, Finger, and Solo. The TRBX304 and TRBX305 also feature newly designed M5 humbucking pickups with built-in thumb rests. The TRBX500-series basses are equipped with a 3-band active EQ that can be bypassed for passive use without loss of gain. New H5 humbucking pickups are featured, along with a battery alert LED.
