Yikes...that's expensive for a US Musicman SUB- I see them for $600 or less where I live.
I own a passive US Musicman SUB, a Sterling Ray34 (in my user pic) and have owned four Sterling SUB 4s (no longer). I also own an inexpensive US made Peavey Fury that I agree with you, is excellent so I know where you're coming from.
Well, keeping your experience with US Peavey basses in mind then no question, the quality of the US Musicman SUB is better - you can literally feel (rounded fretboard) and hear it (again, I have the passive, but I have tried the active version). If you prefer a thinner neck, you can either go with a Sterling Ray24 (or the older Ray34CA) or some of the Ray34 models have thinner necks. Important to note-the "new" Sterling Ray24 which replaces the Ray34CA or classic now uses a Sterling designed ceramic pickups rather than one based on the Musicman's Alnico so the price of one is a little cheaper than it used to be, the pickups on the Sterling Ray4 SUB series are also Sterling designed ceramic ones so neither of these Sterling models are going to sound as "authentic" as the US Rays as the Sterling Ray34 (closer in design to the MM, with the Alnicos). That being said, really they're all good basses in their own ways, the Sterling SUB is a terrific bass for the price and a good option if you want to save a little more money. if you can, I would recommend paying that little bit more for a Sterling Ray34 (or if you can find a Ray34CA) and you'd have the best possible Ray that's not branded Musicman. To be honest, I'd be perfectly happy with the Sterling Ray34 if I didn't already own a MM SUB. You do notice a difference between the Ray34 and Ray4 SUB Series, there's less of a price difference and imo, a more realistic justification for paying a little bit more.
The US Musicman SUB IS every bit a Musicman Stingray Classic as it has the 2 band EQ. The finish is where the company cut corners to meet the lower price range of these, but it is a true Musicman Ray.
For reference, the cheapest Ray I own or have owned is the US made Musicman SUB, I bought it for $160.
If I had to compare them to the Fender hierarchy, roughly it would go like this.
US Fender = US Musicman Ray - or with cheaper finish US Musicman SUB
Squier CV =Sterling Ray34 or the now discontinued Ray34CA.
Squier VM =Sterling Ray24
Squier Affinity=Sterling Ray4 SUB Series
3 of the 4 Sterling SUBs I used to own.
