Lightweight construction yet heavy, sustaining tone.

The RBX4 A2 defies the conventional wisdom that the more uniform and heavy the material, the better the sound. Yamaha has challenged this concept with an advanced technology called Alternative Internal Resonance, or AIR. AIR combines lightweight and resonant softwoods between harder tonewoods creating an instrument loaded with sustain and tone while maintaining an ultra lightweight construction. Already proven in the RGX line, Yamaha now offers this sustain and tone in the RBX line with the RBX4 A2 bass guitar.

Easily the Best value for under $400

Ask me a question

This bass rocks. It is light and well built. the pick ups are quiet but clear. For Jazz this axe is really top notch. I have some fenders and it is equally good and better than my buddy's Schector, Squire, Ibanez and Washburn. Do not mistake light for fragile. It is built well. and I can play it alot longer than my thunderbird or jazz shoulders appreciate that difference.

Old guys, lissen up!

By shep-cInN4

from Madison Alabama

I have been looking for a light weight bass, as my basses of choice are a 63 p-bass 4 string, and a warrior soldier 5 string. Both are heavy. I have back problems (hey, I' 55 years young, high milage) from time to time. I play in praise band every Sunday and practice Tuesdays, and stand during those times. The concept of a light weight bass is appealing as one gets older. I tried the Yamaha, and as is true for Yamaha across the board, this thing is total BANG FOR THE BUCK.Other tahn the thing looking very "guitar hero", and feeling more plastic than wooden (I love the feel of my p'bass), this is a great deal. The pick ups have a nice, somewhat unique tone, that I have found very easy to dial in a sweet, clean sound. If you are a beginner or pro looking to leave the vintage stuff at home, check this bass out. This sale price is a steal. Your back will be thanking Yamaha.


its good, but not for me

I tried this bass out and the whole time played this bass I felt like I was going to break it. It sounded good, not great but good. Playability was nice, the neck had a real nice U shape, but it just felt too tiny and fragile for my taste.


Couldn't be happier

This Bass does everything I need it to do; it's very playable and sounds great. I couldn't believe the low price...when I ordered it, I didn't know what to expect, but the Yamaha RBX4 A2 far exceeded my expectations.


The bass of tomorrow, today!

By Anonymous

from Undisclosed

The whole "Proprietary A.I.R. Technology" thing may seem like a gimmick, but this bass really does live up to the marketing. It's light, comfortable, balances nicely, and has good sustain. The 24-fret maple neck is bright and articulate and feels great, with good upper-fret access. The overall feel of the instrument is kinda futuristic and plastic-y, but at the same time totally solid.You can get a lot of different sounds out of the J-style blade pickups. They don't necessarily excel in a particular style, but are totally capable for rock/alternative stuff, and especially jazz. Lots of complex highs and mids. The low end is totally solid, but you're not going to get thunderous, beefy lows for metal or reggae. Overall, the tone is versatile and surprisingly usable. The truss rod on mine was a bit sticky/difficult to adjust when I first got it, but it's settled in since then.Overall an awesome instrument. Maybe not for everyone, but definitely worth checking out.


Great Bass, Great Bargain

By Snab

I got a black one at the lower price. I had some interest in this bass already, and when I saw that they were blowing out the black ones, I got one. It's a very nice instrument, kind of like a Jazz with 24 frets. The pickups are big and beefy sounding, and I've been able to get a nice low action. Mine isn't terribly light at about 7-3/4 lbs, but it's light enough. I've had quite a few nice basses, including MIJ and MIA Fenders, and this one fits right in with them in terms of quality.


Pimp bass!

An incredible buy! This baby has incredible tone, and is versatile. Looks great and sounds incredible. It is light compared to a p-bass, but not the lightest thing around.


Best Bass For The Price

By CMoore

from Huntsville, AL

Good solid bass with good sound. Surprising tone and sustain considering the weight. I guess AIR really works! The single coils are fairly quiet. The only thing I don't like is the way the cheap, top piece of the headstock was put on. Still, I'm beginning to like this bass better than my Schecter Stiletto Elite which cost over $600. You can't go wrong . Buy this bass!

Better then what your paying for

By Delaybass

from Long Beach CA

Just got this last week with some of my tax money and it is worth way more then this clearance price. I have been playing 11 years and have had a handful of basses over that time and this is one of the best 2 I have owned. Good deal of different tones can be pulled out, mainly for me an aggressive/treble tone, but many more possible. Action did come a bit high but nothing that cant be fixed easy, get it while you can.


Plays great....looks?

By Skylinealx

Yamaha has a good reputation of making quality instruments, this bass is a great example. It plays very very well, suits any kind of music. The only problem I think is that it looks like something you plug into a Nintendo Wii not a amp.
