A classic tonewood recipe
The TRBX604FM is built from quality tonewoods. A solid alder body provides a balanced yet punchy foundation for this bass's tone, yielding equal doses of lows, mids, and highs. A stunning flamed maple top frames 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 are the final ingredients in the TRBX604FM's classic tonal recipe.

Flexible active 3-band EQ
Bassists appreciate the clean, open tone exhibited 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-grade active/passive 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. And as an added bonus, a battery-alert LED prevents unexpected power losses when you're performing onstage.

Comfortable 5-piece maple/mahogany neck
If you're searching for extreme comfort, you'll enjoy playing the TRBX604FM. Its 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. And you'll benefit from superior tuning stability and reduced overtones, thanks to a headstock that virtually eliminates lateral string tension.
