Yamaha TRBX174 4-String Electric Bass Guitar
The Yamaha TRBX174 is the entry model of the TRBX range, a full-scale four-string bass with a mahogany body, bolt-on maple neck and 24-fret rosewood fingerboard. It pairs a split single-coil neck pickup with a single-coil bridge pickup, controlled by two volumes and a master tone.
It is a natural first bass for students and beginners, and a dependable spare or practice instrument for more experienced players. The standard 34" scale and uncomplicated controls mean you learn on the same feel you will meet on stage and in the studio.
Key Features
Split Single-Coil and Single-Coil Ceramic Pickups
A split single-coil pickup sits in the neck position and a single-coil in the bridge position, both with ceramic magnets. The neck pickup delivers a rounded, full low end, while the bridge pickup adds focus and definition. Blending the two gives a wide spread of classic bass tones.
Simple Volume, Volume and Tone Controls
Each pickup has its own volume knob, with a single master tone control to brighten or darken the sound. The layout is quick to learn and makes it easy to hear how each pickup contributes to your tone.
Mahogany Body on the TRBX174
The TRBX174 has a mahogany body finished in gloss polyurethane. It shares the TRBX family look and gives the bass a solid foundation for its pickups.
TRBX174 Maple Neck with 24-Fret Rosewood Fingerboard
The bolt-on maple neck has a satin polyurethane finish and a rosewood fingerboard with a 10" (250 mm) radius and 24 medium frets. That gives two full octaves on every string, with a nut width of 40 mm and 19 mm string spacing at the bridge.
Full 34" Scale
With a standard 34" (863.6 mm) scale, the feel and string tension match the long-scale basses you will find in rehearsal rooms and studios. Skills learnt on it transfer directly to other full-size basses.
Vintage-Style Bridge and Covered Tuners
A vintage-style bridge anchors the strings at the body end, with 19 mm string spacing. Covered tuning machines handle tuning, and the bass is strung with 0.045-0.105 gauge strings.

Four Gloss Finishes at YMS
YMS offers the TRBX174 in Black, Dark Blue Metallic (listed as Dark Blue), Old Violin Sunburst and Red Metallic. All are gloss polyurethane finishes over the mahogany body.

Frequently Asked Questions
What is the difference between the TRBX174 and the TRBX174EW?
They share the same specifications: mahogany body, maple neck, 24-fret rosewood fingerboard, ceramic split single-coil and single-coil pickups and volume, volume and tone controls. The TRBX174EW adds a laminated exotic wood top and a matching headstock for a different look.
How does the TRBX174 compare with the TRBX304?
The TRBX304 moves up to a 5-piece maple and mahogany neck, ceramic double-coil pickups, a 2-band active EQ with a 5-position Performance EQ preset switch and a die-cast bridge. The TRBX174 keeps things simpler with a maple neck, two volume controls and a master tone, and a vintage-style bridge.
Is the TRBX174 a good bass for beginners?
Yes. It has a full 34" scale, a 40 mm nut and simple controls, so beginners can concentrate on technique rather than settings. It is the entry model of the TRBX range, built to Yamaha's usual standards.
Does it come with a case or gig bag?
No. Yamaha does not list a case for the TRBX174, so we recommend adding a gig bag. It comes strung with 0.045-0.105 gauge strings.
Is this a full-size bass?
Yes. The TRBX174 has a full 34" (863.6 mm) scale with 24 frets, the same scale length as every other TRBX model.
