Is the Yamaha TRBX604FM worth it?

Yes, for players wanting a versatile active bass with solid build quality. It competes well with basses costing more, though some prefer passive models for a more classic tone.

How does it compare to the TRBX504?

The TRBX604FM adds a flamed maple top and upgraded pickups/preamp for a brighter, more refined tone. The 504 is simpler and slightly cheaper, but the 604FM offers more tonal options.

Does it have an active or passive preamp?

It has an active 3-band EQ preamp, powered by a 9V battery. There is no passive mode, so the battery must be installed for sound.

What strings does it come with?

It ships with Yamaha's stock strings, which many players replace soon after purchase for better tone and feel.

Is the neck comfortable for small hands?

The neck has a modern C-shape and 10-inch radius, which most players find comfortable. However, those with very small hands may prefer a thinner neck profile.

The bass, a 9V battery, a truss rod wrench, and documentation. A gig bag is not included.

About the Yamaha TRBX604FM 4-string Bass Guitar

The Yamaha TRBX604FM is a right-handed, 4-string electric bass guitar. It has a solid alder body with a flamed maple top. The alder gives a balanced tone with lows, mids, and highs, and the maple top adds brightness, bite, and sustain.

The neck is a 5-piece maple/mahogany design with a rosewood cap. It has a comfortable profile and a refined neck joint that balances strength, vibration transfer, and upper-fret access. The headstock is designed to virtually eliminate lateral string tension, which helps tuning stability and reduces overtones. A high-mass die-cast bridge transfers string vibrations to the body.

Two YGD H5 pickups with a quad-pole-piece design and Alnico V magnets give a clean, open tone with ample output and dynamic sensitivity. The onboard preamp has a 3-band EQ and works in active or passive mode, with a level-matched output in both. Tone-switching circuitry moves from treble control to master passive tone. The bass also has a plate-mounted jack socket and a durable finish.
