In response to David's excellent post, I'd offer the following.
I own a Sadowsky Vintage 4, a relatively early Lakland 4-94, a '73 Fender Jazz Bass (modified with a Badass II Bridge, Seymour Duncan Pickups, Schaller Tuners, and a J-Retro preamp), and an '05 MIA Fender Jazz Bass Deluxe. I also own five Alembics (a SC Sig Std, a Dragon's Wing, two Essences, and a Europa; my Series II Entwistle replica is nearing completion).
David is absolutely right when he states that it's difficult to judge which bass is the right one for any one person. This being said, I can say that the Sadowsky, Lakland, and my modified '73 Jazz are heads and shoulders above my MIA Jazz Deluxe. It's not that the MIA JD is a bad instrument, it isn't. Tonally, to me, the Sad, Lakie, and the '73 are just better.
Now, is the Sad all that it's cracked up to be? Yep, it is, for me at least. Regardless of how it's made, it has that great Fender tone down in spades. The workmanship is flawless, the fretwork immaculate, and the setup perfect. IMHO, Roger took the Fender model and took it to the next level. And live, it just kills in the mix. I was a naysayer until I tried it (many had told me about this and I was skeptical). It really is all that, to me anyway.
The Lakie, well let's just say it's like a Jazz Bass and a Stingray got together and decided to raise a family. The 4-94 is the result, and it's amazing. It's been my go to bass in the band I've been playing with recently, even more than my Alembics. To me, that instrument is definitely worth every penny. The coil tap on the the Lakie's MM-style bridge pickup should be standard on every MM product if you ask me - an extremely versatile feature IME. The neck is just about perfect for me too - thin in depth, and only slightly wider than a Jazz bass at the nut (I prefer Jazz style necks for the most part). Build quality is flawless, as is the finish (mine has a beautiful quilt maple top over an ash body).
David's right - one is paying a large premium for a Sad or Lakie when compared to an Alembic given the construction of the instrument and the methods employed. In the end only the individual can judge whether it's worth it. For me it was. My Sad I bought new; my Lakie I bought used for about $1450. Best $1450 I've ever spent bass wise (with the exception of the Burkha King, of course).
BTW, the pickups in my Lakie are Barts; the Sad has Sadowsky humcancellers. Lakland recently started making their own pickups and preamps as well, and that's what they use in their instruments for the most part now. Sadowsky has installed Nordstrands in some models too.
To hear the my Sadowsky in action, go to
