I bought one about a week ago. A 2009 Musicman Stingray. 3 band EQ, single pickup. Candy red, rosewood fretboard
I've only really had Fenders before, so I can only describe it relative to those...
Build quality is great. Components seem excellent quality, and the fit and finish is great. If you've played fenders before, you'll find the neck is very much like a Precision.
It's quite heavy, but not too heavy. Nice and solid. Sounds nice acoustically.
The G string was a bit quieter than the others. I'm convinced it's because the pickup polepiece doesn't line up properly with the G string. This is apparently a common issue with Stingrays. I fixed it by raising the pickup at the treble side, and managed to get the string volumes balanced enough to where it isn't an issue. You'd think in an otherwise very well designed bass they would have fixed this years ago. But no. Apparently the new ones DO have the polepieces in the right place... but 2 grand's a lot to pay imo for that
My takeaway from the G string polepiece issue is that it's pretty sensitive to how you have your pickup height set - so be aware of that
Re the sound and having a single pickup. The most noticable thing is that the kinds of warm, vocal mids you might get from a precision are totally absent. And the second thing is that the low end is deep and tight. I heard the preamp has a high pass filter, and it sounds like it. There's loads of thick, punchy bass, but it somehow has a tightness to it. As if it rolls off quickly below 40hz.
My main bass is/was a precision, and I use an SVT. So my go-to sound is that classic grindy rock tone (with a plectrum) with the SVT deep switch in, and a bit of mid scoop. Loads of low end, but it's more of a fat and woolly low end, and those precisiony, expressive mids. You can't get anything close to that with the Stingray. With a plectrum, you get LOADS of zingy top end, and that tight bass, with no real Fendery mids no matter what you do. It's very scooped, even when you goose the mids on the EQ
For a punk or rock gig I would leave the Stingray at home and take the Precision, unless it was something modern like RATM or RHCP etc
For a pop/funk/disco type gigs, the Stingray would be perfect. It seems to have been primarily intended for fingerstyle players. The frequencies that the pickup and preamp accentuate are ideal for a nice tight, modern fingerstyle sound. Lovely for fingerstyle
The 3 band EQ is interesting. I tend to leave everything centered. Sounds best to me that way. The treble and bass tend to either let you take far too much off, or add far too much on. The middle isn't really a traditional mid frequency knob like on a fender amp, it's more like a knob that lets you make the sound go from fairly scooped to very scooped... whatever you do, there isn't much mids
I heard someone say (and I agree) that a fender jazz (both pickups on) is more scooped than a precision, with deeper lows and higher mids. And that the Stingray is even more scooped - deeper lows and has even higher frequency mids. I think that's a good way of putting it. If there's a path from P to J, then the Stingray is the next step along
I think no matter what you do it'll sound like a Stingray. But I think it has enough to make it a fantastic bass in the right context. It's certainly not a swiss army knife, and almost certainly the wrong bass for certain things
I really do like mine. Got it off eBay for £900, and I'm glad I got it. Not sure I'd buy a new one for the prices they're asking now
