Yamaha Billy Sheehan Attitude 3 Bass Review: Built for One Purpose

The Yamaha Billy Sheehan Attitude 3 is a signature bass — and signature instruments are a specific kind of purchase. You’re not just buying a bass, you’re buying into a player’s philosophy of what an instrument should do. That’s worth examining before you spend the money.

Billy Sheehan is one of the most technically advanced rock bassists alive. His playing involves heavy picking, aggressive right-hand technique, chording, and a tone that cuts through two guitar stacks without breaking a sweat. The Attitude 3 is built for that specific purpose.

Rating: 5/5

Verdict: The Yamaha Attitude Limited 3 is Billy Sheehan’s signature bass: a DiMarzio woofer pickup at the neck, a DiMarzio Will Power P-style pickup in the middle and stereo outputs that let you send each to its own amp. The big neck and aggressive tone are built for loud rock. It is ideal for hard-hitting rock bassists and Sheehan fans. It is not for beginners or for funk and jazz players.

The Design Philosophy

The Attitude 3 has two pickups: a Yamaha-designed DiMarzio woofer pickup in the neck position and a DiMarzio Will Power split-coil P-style pickup in the middle. There’s no bridge pickup. And yes — two output jacks. In stereo mode the woofer and middle pickups each get their own output, so you can send them to two separate amps and blend two different sounds at the board or with a mixer.

For most players this is overkill. For a player who needs to fill a large sound in a loud rock context, it’s a practical solution to a real problem. The dual-output design lets you dial in low end and body from the woofer pickup on one signal path and midrange punch from the P pickup on the other, independently.

You can also run it mono through a single amp — the bass functions fine as a standard instrument. But you’d be leaving half the design on the table.

The Neck

Big and thick — that’s how Yamaha itself describes it — with a 44.5 mm nut, 19 mm string spacing at the bridge, jumbo frets up to the 16th and scallops from the 17th to the 21st. If you have larger hands and play rock with aggressive right-hand technique, this neck will feel natural immediately.

If you have smaller hands or you play primarily fingerstyle funk or jazz, this neck will feel like a lot to hold onto. That’s not a flaw — it’s a signature instrument designed around one player’s style. Know what you’re buying.

The Tone

Aggressive. The woofer pickup at the neck gives you a heavy, powerful low end and a solid fundamental. The P-style middle pickup adds midrange punch and bite. Together they create a tone that is built to compete with loud guitars in a live rock context.

I played it through a single amp and it sounded powerful and present. Running it through two amps the way Sheehan intends — that opens up a different level of control over your sound. The stereo routing is where this bass really shows its purpose.

Who Should Buy This

Rock bassists who play loud, who dig in hard, and who need a bass that won’t get buried in a dense mix. If you’re inspired by Billy Sheehan’s playing and you want to explore that kind of aggressive, technical rock bass approach — this instrument is designed exactly for that.

For everyone else — even excellent players who work in different styles — there are better fits. A funk player doesn’t need this bass. A jazz player doesn’t need this bass. The Attitude 3 is a specialised tool for a specific musical context and it’s very good at what it does.

I’d also note this is one of the few signature bass instruments where the design actually reflects how the artist plays, rather than being a standard instrument with a famous name on the headstock. That authenticity matters.

Build Quality

It’s a Yamaha, so the construction is solid throughout. The hardware is quality, the fret work is clean, the finish is consistent. Yamaha’s manufacturing standards apply regardless of the price point, and the Attitude 3 benefits from that.

The electronics are well-shielded — important on a bass with two separate signal paths. Noise is not a problem in normal playing conditions.

FAQ

What makes the Yamaha Billy Sheehan Attitude 3 different from other basses?

The dual-output design — one output for the neck woofer pickup, one for the middle P-style pickup — allows running two separate signal chains and blending them independently. This is a unique feature designed specifically for Sheehan’s two-amp live setup.

Can you use the Yamaha Attitude 3 with a single amp?

Yes. Set the push-pull on the middle volume to mono and it functions as a standard bass through a single output. You won’t take advantage of the dual-output design, but the instrument plays and sounds like a quality two-pickup bass through one amp.

Is the Yamaha Billy Sheehan bass good for beginners?

No. The big, thick neck, aggressive tone character, and dual-output complexity are all aimed at advanced players with a specific style. A beginner would be better served by a standard beginner instrument before tackling something this specialised.

What kind of music is the Yamaha Attitude 3 designed for?

Hard rock and heavy rock primarily. The tone is aggressive and designed to compete with loud guitars. It’s not well-suited for jazz, funk, or styles where a cleaner, more polished tone is needed.

How does the dual output work on the Yamaha Attitude 3?

In stereo mode the neck woofer pickup routes to one output jack and the middle P-style pickup to a second output jack. Running cables to two separate amps lets you blend the two sounds independently — typically low end and body from the woofer, midrange punch from the P pickup.

The Yamaha Billy Sheehan Attitude 3 exists in a specific market niche: rock bassists who play fast, need reliability, and don’t want to look like they compromised by not playing a precision. Sheehan’s influence on the design is unmistakable — the neck is scalloped from the 17th fret up, and the dual pickup configuration covers everything from the woofer pickup’s heavy low end to the P pickup’s midrange attack.

What I find interesting about studying Billy’s technique through this instrument is how the bass is designed to reveal his approach. The woofer pickup handles the bottom, the middle P pickup handles the midrange punch, and he blends them intentionally depending on what the song needs. It’s not a one-knob bass.

For players who want to understand aggressive rock bass beyond just playing with a pick and turning up the gain — this instrument is worth spending time with, even if it’s not your primary sound.
