I've recently acquired a BB735A and I'm really loving the bass. Everything about it is spot on: the neck is amazing for my hands, I can play on it for hours and I don't get tired; I love the looks on this bass, specially the dark coffee sunburst that looks amazing and combines well with the black chromed hardware; the construction details are amazing, from the convertible bridge to the 6 screws neck joint, to the graphtech nut, everything is spot on; and the sound... man, this thing is punchy and articulate. Everything a bass should be. After playing with it at some gigs, I have to say that this is my perfect workhorse. It covers so many grounds... I read some reviews on this bass saying that the eq was the weakest part of this bass, but I'm really loving it so far. And what I really like about it is that it's more subtle than most eqs that I tryied, and in a good way IMHO. By that I say that the way that I like to set my eq is to make minor adjustments to the tone of the bass, concerning certain songs or to adjust to some of the band settings. And this eq does it in the right way. It doesn't boost drastically the frequencies in a way that's totally unusable, but it goes to where it needs to go, and the frequencies it adjusts are just right for these pickups. And the passive mode sounds so good as well. You can get all the classic tones with this bass in passive mode, and it doesn't loose that much volume compared to the active mode when all eq is flat. When I compare it with my BB1024X I agree to most reviews that I've read here. The BB1024X has a much more vintage sound, warmer, smoother and with more output compared with the passive mode on his younger brother. It sounds great with flats and I almost never change the switch from the front pickup. The BB735A has a brighter tone, more high mids to it, and I frequently have to cut a bit of highs, you can say that it has a more modern sound to it. But it sits so well in the mix. It sounds punchy and with more presence. And it covers so much tonal ground. The guy that I bought this from had set some Fodera rounds on it and they sound really good. Honestly, I could make a living with these two basses only. I have to say that Yamaha really did an amazing job with this bass. I don't know about the other models in the series, but this one is spot on. I believe that in construction quality and sound, this bass is way above its price range. I didn't get a single bad review while using it and everybody said that this was the best sounding bass that I brought to play.
