This Value-packed Bass Is Loaded with Features

Loaded with professional features, the Yamaha TRBX604FM offers incredible value in a bass guitar. A classic tonewood combination of solid alder and stunning flamed maple delivers punch, bite, and sustain by the truckload. A comfortable 5-piece maple/mahogany neck combines excellent playability with superior tone and stability. Experience maximum sonic flexibility, by way of the TRBX604FM's YGD H5 pickups and audiophile-grade active/passive 3-band EQ. Beyond that, a high-mass die-cast bridge and innovative headstock design provide optimal vibration transfer and tuning stability. A battery-alert LED and satin matte finish round out the impressive TRBX604FM.

A classic tonewood recipe

The TRBX604FM is built from quality tonewoods. A solid alder body provides a balanced yet punchy foundation for this bass's tone, yielding equal doses of lows, mids, and highs. A stunning flamed maple top frames the TRBX604FM's basic tone with brightness, bite, and sustain. And the added snap and warmth provided by its 5-piece rosewood-capped maple/mahogany neck are the final ingredients in the TRBX604FM's classic tonal recipe.

Flexible active 3-band EQ

The bassists here at Sweetwater appreciate the clean, open tone exhibited by the TRBX604FM's dual YGD H5 pickups. Plug in, and you'll experience ample output and dynamic sensitivity, by way of these pickups' quad-pole-piece design and robust Alnico V magnets. Beyond that, the TRBX604FM is loaded with an audiophile-grade active/passive 3-band EQ. This flexible circuit offers a level-matched output in both passive or active modes, and tone-switching circuitry that moves seamlessly from treble control to master passive tone. And as an added bonus, a battery-alert LED prevents unexpected power losses when you're performing onstage.

Comfortable 5-piece maple/mahogany neck

If you're searching for extreme comfort, you'll enjoy playing the TRBX604FM. Its TRBX neck design combines a comfortable profile with 5-piece maple/mahogany construction for excellent tone and stability. This bass's refined neck joint reflects the perfect balance of strength, vibration transfer, and upper-fret access. And you'll benefit from superior tuning stability and reduced overtones, thanks to a headstock that virtually eliminates lateral string tension.

Yamaha TRBX604 is incredible

Thank you Sweetwater for an incredible bass. Thank you for your 55-point inspection. When I got the bass, the first brand new bass I have owned btw, I thought I was going to be in for some work when it got here. I was dead wrong. Even when I put new slightly higher gauge strings on it, the intonation was right on. String height, no fret buzz. Speaking of frets...smooth and not one sharp edge. I couldn't be happier right now with this bass. I was used to my Ibanez with the Big S 4 nordstrands, which are bright.

I played this TRBX604 and the tone...the one was warm, vintage, and still punch through. I can't wait to play it at church. From payment to my door, two days...just two days. Thank you for the free shipping and it was packed nice and tight. Great job all the way around. Thank you for this bass. Thank you for taking the time to perfect it and pack it and get it to me so quickly. This is my first purchase with Sweetwater.

Extremely Versatile!

As a long time guitar player, I've always enjoyed the sound of the electric bass guitar. Now that I have more time to explore different musical avenues, I decided to buy one, and after researching and playing several models, I settled on the Yamaha. TRBX604FM. It turned out to be a great choice - Excellent craftsmanship and attention to detail, very comfortable to play, great looks, but best of all is the sound! The active equalizer enables an amazingly wide range of tones, including an incredibly accurate reproduction of an upright acoustic, perfect for jazz. This is an excellent value.
Music background: Playing guitar, all genres, since the mid 1960s.

Awesome Guitar

I just received my Bass on this past Monday. Last night I had band practice and played it for the first time. Sound and playability are awesome. I have a nice American P-Bass that I normally use but I think it will be sitting it's case quite a bit now. Highly recommend this guitar.
Music background: Playing guitar for 28 years. Member of a local Classic Rock band.

Yamaha TRBX604FM

Outstanding build quality. Fabulous fit & finish. Plays beautifully!! My favorite feature on this instrument is the ability to go from active to passive with the flip of a switch. Great tones from the alder body. I could go on but you get the idea. Very happy with this purchase.

TRBX604FM

First off my experience with sweetwater has been excellent. Upon getting this bass i did have some small issues. The neck is so thin i had to play with truss rod a few times. Seems like i would set it and jam, then next day do it all over again. This happened a few times. Very sensitive to temperature change as far as truss rod and staying in tune. The good about this bass is it sounds fantastic. Get any sound you want with these pickups. Briidge pickup with active on and bass cranked and highs turned down sounds just like musicman stingray. Awesome tone. Took some time to get used to the small fret marker inlays. Cant see them at playing angle because behind strings. This is a beautiful looking and sounding bass. Very pleased and sweetwater was excellent.
