Yamaha’s Value- and Performance-packed TRBX Bass

Loaded with professional features, the Yamaha TRBX604FM upends the performance and value proposition for electric bass guitars. A classic tonewood combination of solid alder and stunning flamed maple delivers punch, bite, and sustain by the truckload. Meanwhile, a comfortable 5-piece maple/mahogany neck combines excellent playability with rock-solid stability. In the electronics department, Yamaha’s YGD H5 pickups and onboard preamp serve up wide-ranging sonic punch and the flexibility of studio-grade 3-band EQ. The TRBX604FM’s tonal stability is reinforced with a high-mass die-cast bridge and an innovative headstock design that provide optimal vibration transfer and tuning stability along with epic sustain.

A classic tonewood recipe

Yamaha specified premium tonewoods for the TRBX604FM. A solid alder body provides a balanced yet punchy tonal foundation, yielding equal doses of lows, mids, and highs. A stunning flamed maple top enhances the TRBX604FM's basic tone with brightness, bite, and sustain. And the added snap and warmth provided by its 5-piece rosewood-capped maple/mahogany neck is the final ingredient in the TRBX604FM's classic tonal recipe.

Flexible active 3-band EQ

The bassists here at Sweetwater appreciate the clean, open tone delivered by the TRBX604FM's dual YGD H5 pickups. Plug in, and you'll experience ample output and dynamic sensitivity by way of these pickups' quad-pole-piece design and robust Alnico V magnets. Beyond that, the TRBX604FM is loaded with an audiophile-quality preamp with 3-band EQ. This flexible circuit offers a level-matched output in both passive or active modes, and tone-switching circuitry that moves seamlessly from treble control to master passive tone.

Comfortable 5-piece maple/mahogany neck

Bassists searching for extreme comfort will savor playing the TRBX604FM. Yamaha’s acclaimed TRBX neck design combines a comfortable profile with 5-piece maple/mahogany construction for excellent tone and stability. This bass’s refined neck joint reflects the perfect balance of strength, vibration transfer, and upper-fret access. Finally, you’ll benefit from superior tuning stability and reduced overtones, thanks to a headstock that virtually eliminates lateral string tension.
