Premium mahogany tone. Active/passive versatility. Built for players who mean business.
The Yamaha TRBX504 is a 4-string premium electric bass that delivers serious tone without the premium price tag. Featuring a solid mahogany body, a sculpted 5-piece maple/mahogany neck, and Yamaha's acclaimed YGD-designed H5 Alnico humbucking pickups — this bass sounds and plays like it costs a lot more.
The standout feature is the active/passive preamp with 3-band EQ — switch between active mode for punchy, articulate tone with boosted lows and highs, or flip to passive mode for a raw, natural sound straight from the pickups. A battery alert LED ensures you never get caught mid-set with a dead battery.
