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.

Works great!

I've been playing this daily for a couple weeks and enjoying myself immensely! I read a few reports of issues with the active/passive switch, but for me it's worked every time, and silently--there's no pop when I toggle the switch. The electronics must be well-shielded; I hear no hum in locations where my older (unshielded) bass picked up a lot of hum. The only thing I can think of to complain about is a little hiss in active mode, most noticeable if the treble's boosted. The hiss goes away in passive mode. I've verified that passive mode continues to work after the battery goes dead. Out of the box all it needed was a little tuning and it was ready--action felt low, no fret buzz with my playing. It feels comfortable. (I play mostly standing up with a strap.) The controls give a good variety of usable sounds. (But my previous bass was a passive RBX260 with only a single P-style pickup and tone control, and I'll confess to not a lot of experience here.)
