A Serious Bass That Looks the Part
There's a certain kind of bass that just makes you want to plug in and play — and the Yamaha TRBX604FM in Dark Red Burst is exactly that. That flame maple top with the deep, gloss polyurethane Dark Red Burst finish isn't just eye candy; it's matched by an instrument that actually delivers from first note to last. Whether you're running direct into a recording rig or pushing through a stage monitor, this bass is built to be heard.
The TRBX604FM sits at the top of Yamaha's TRBX600 series, and it earns that spot through a combination of real tonewoods, thoughtful electronics, and a neck that genuinely encourages you to play more. It's the kind of instrument where the specs and the feel line up — and that's not as common as it should be.
If you're a working bassist who needs one instrument that can cover a wide range of sounds — from warm and thumpy passive tones to punchy, scooped active tones — this is a smart pick.
This item is a B-Stock guitar sourced directly from the manufacturer. It is new and has never been previously owned. The photos shown are of the exact instrument you will receive. Before shipment, our licensed technician will inspect and professionally set up the guitar to ensure it is playing its best. During our inspection, we noticed ROUGH HEEL CUTOUT TOP EDGE. (see pictures) Please note, these may not be the only cosmetic imperfections. As a B-Stock instrument, there may be additional minor blemishes that are small in nature and do not affect playability or performance.
Solid Alder Body with Flamed Maple Top
The foundation here is a solid alder body — a tonewood long favored for its balanced frequency response, delivering clear highs, punchy mids, and solid lows without any one frequency range dominating. On top of that sits a flamed maple top, which adds brightness and bite to the alder's balanced character and gives this bass its striking visual personality.
Yamaha's 3D-sculpted body contouring isn't just for looks — the mass-optimized design is tuned for comfortable weight distribution, so the bass sits naturally whether you're standing through a long set or sitting in for a late-night session. The Dark Red Burst finish on this model is Gloss Polyurethane, giving it a rich, deep appearance that really makes that flame figure pop.
A Neck Built for Speed and Stability
The five-piece maple/mahogany neck is one of the TRBX604FM's standout features. Alternating strips of maple and mahogany are laminated together, which gives the neck exceptional resistance to seasonal wood movement while blending the snap and clarity of maple with the warmth of mahogany. The rosewood fingerboard adds a smooth, comfortable playing surface and a touch of tonal warmth on top.
Yamaha's slim neck profile — just 38mm at the nut and 19.5mm thick at the first fret — keeps the TRBX604FM fast and approachable without feeling flimsy. The bolt-on neck joint was developed to balance strength, vibration transfer, and upper-fret access, and Yamaha's straight-pull headstock design virtually eliminates lateral string tension for rock-solid tuning stability.
YGD H5 Pickups and Active/Passive Electronics
At the heart of the TRBX604FM's sound are two YGD H5 double-coil pickups — Yamaha Guitar Development's own design. Each pickup features a quad-pole-piece layout with Alnico V magnets, which gives them ample output to drive the active preamp while retaining enough sensitivity and detail to shine in passive mode as well.
The onboard electronics give you master volume, a pickup balancer, and a full 3-band EQ (bass, middle, treble) in active mode — plus an active/passive toggle that seamlessly switches to a master passive tone control when you flip it. The level-matched output between modes means no sudden volume jumps mid-set. A battery-alert LED on the back panel rounds out the practical touches — no more surprise dead batteries at showtime.
