An Extremely Versatile 4-string Bass!

The Yamaha TRBX504 4-string bass guitar brings versatility, killer looks, and amazing performance together in a complete package. This sleek-looking, great-sounding bass gives you a comfortable Yamaha body shape and a fast-action bolt-on 5-piece maple/mahogany neck with a smooth-playing rosewood fingerboard. A pair of humbucking pickups delivers hum-free sound while powerful active electronics let you optimize your bass for different playing styles. Factor in the Yamaha TRBX504’s solid hardware and thoughtful design, and you’ve got a great-looking bass that’s ready to rock any stage or studio session.

Comfortable body with progressive styling

One look at the Yamaha TRBX504 4-string electric bass, and you know it means business. A deep cutaway gives you clean access to the higher registers for soloing, while the pronounced upper bout provides balance (and looks cool). The 5-piece maple/mahogany neck has a comfortable and fast-playing profile. The TRBX504 sports a precision fitted neck joint that contributes to the instrument's clear, punchy tone. And the straight string pull of the headstock offers improved tuning stability and reduces overtones. You’re going to love the way the TRBX504 looks, plays, and feels!

Humbucking pickups deliver massive bass tone

Yamaha loaded the TRBX504 with a pair of custom-designed HHB5 humbucking pickups. These pickups house Alnico V magnets and two pole pieces per string for big, open tone without any hum. On top of amazing pickup tone and performance, the TRBX504 has an extremely versatile set of active electronics so you can be ready for any gig. It starts off with an active/passive switch followed by a 3-band EQ, a balance control, and volume. The EQ lets you sculpt the perfect tone for live gigs and studio sessions. No matter what kind of sound you need, the Yamaha TRBX504 4-string bass can get you there in seconds!

Perfect for my studio

I've been a musician for 40 years and this is one of my best instruments. Great tone and intonation. Feels awesome in my hands and music just flows through me into it. I love it and you probably will too.
Rated 5/5

Great instrument & Great Customer Service

I have gone through a handful of basses trying to find the right feel and versatility that I wanted, including 2 American made, high priced models which were both quite disappointing. All things considered, this Yamaha blows them away in every aspect, for 1/3 the price.
It is obvious that Yamaha really does their homework to produce high quality instruments. This bass sounds awesome, is about as versital as it gets with the active/passive switch and the eq, built with high quality components, is fairly lightweight and has a perfectly balanced feel. The slim neck design is incredibly comfortable and fast, I love the smooth satin finish of it versus painted or gloss necks, which tend to feel "sticky" to me. Between the awesomely designed pick ups and active EQ this thing produces phenomenal sounds. I play through a Fender Rumble v3 500 and it partners well with this bass.
To speak of Sweetwater, I don't think that I will ever buy another instrument elsewhere. Their customer service was amazing, the bass came on time, was packaged with care and was perfectly set up. I really liked the option of choosing the exact instrument that you want out of their stock and being able to view multiple pictures of each individual one before ordering. A nice touch was the sales assistant then sent me all of the studio pictures of the bass that I ordered via email, I know that's not a big deal, but I thought it was a cool touch. Bottom line is that I highly recommend this bass and just as highly recommend that you purchase it from Sweetwater if you want a fabulous experience. I hope someday to get down to their store, it looks incredible!

Great tone and plays great!

Has a deep, punchy tone, yet bright enough to make your playing cut through the mix. The dual humbuckers have a unique sound to them, and you can get more tonal variety out of them than just on split-humbucker, like a p-bass. The active/passive switch is a great feature for a bass at this price point. Altogether this bass is very versatile and sounds much better than any other bass at this price point. Don't be afraid to buy Yamaha. This was my first Yamaha bass and I haven't regretted it. Even though I love the clear tone of a jazz bass, the TRBX model is a whole world of its own. Great quality!

YAMAHA TRBX504 TRANS BLACK

I love this Bass. The sound is outstanding. The two modes (active and passive) are an extra feature that cannot be overlooked, specialty when playing at church or a concert. The neck is so smooth that is unreal the way it feels. In my humble opinion Yamaha has made one of their best bass line they have and will compete with the Fenders, Gibson and Ibanez. I think by far Sweetwater is the best online music store I have deal with. Also I wanted to thanks Ryan Darmos for all of help he provide me and for his professionalism was outstanding.
