Yamaha TRBX504 4-String Sculpted Solid Mahogany Body Electric Bass Guitar

Introducing the Yamaha TRBX504 4-String Sculpted Solid Mahogany Body Electric Bass Guitar
Premium mahogany construction and an advanced active/passive preamp design offer the flexibility and exceptional tonal quality needed to shape the perfect sound.

The TRBX500 series features controls for master volume, balance, 3-band EQ, and an active/passive switch for maximum versatility.

Pickups
The YGD-designed H5 pickups provide a clean, open tone that complements the adaptability of the active/passive preamp design. Their quad-polepiece design and Alnico magnets deliver the power to drive the active circuit and the sensitivity to capture nuances in passive mode.

Electronics (Active/Passive Selector, Battery Alert)
The audiophile-grade active/passive circuit ensures precise tonal control and flexibility, maintaining a consistent output in both passive and active modes. The tone-switching circuitry smoothly transitions from treble control to master passive tone. Gold-plated components enhance conductivity and reliability, while an LED on the back panel indicates low battery to prevent power loss during performances.

Body
Constructed from solid mahogany with a mass-optimized 3D design for balanced tone and comfort, ensuring ideal weight distribution.

Neck
The neck features a rapid, ultra-comfortable profile with a 5-piece maple/mahogany laminated construction for exceptional stability and tone.

Neck Joint
The precision-fitted bolt-on neck joint provides maximum adjustability and clear, punchy tone. The refined neck joint shape, developed through extensive play-testing, balances strength, vibration transfer, and upper-fret access.

Headstock
Straight string pull from nut to machine head reduces lateral tension, improving tuning stability and reducing overtones.

Nut
Nut widths of 38 mm (4-string) or 43 mm (5-string) offer quick, comfortable playability suitable for various styles.

Bridge
The high-mass, die-cast bridge efficiently transfers string vibrations to the body for a rich tone, accompanied by excellent adjustability and durability. The 5-string model with 18 mm string spacing provides exceptional playability for slap or finger styles.

Output Jack
Yamaha metal, plate-mounted standard jack sockets ensure durability and easy maintenance.
