I've heard it said that "one can get 3 Skylines for the price of an American". To that I said "3 Skylines couldn't replace my USA." I own a Deluxe 55-94 and I used to own a 55-01. The 55-94 will always be with me as my end-all bass, hands down. That said, I sold the 55-01 3 months after purchasing it (and took a big $$ hit) because the components, craftmanship, playability and tone were THAT much different. I greatly agree with Fezzey that you can pay more, but you can't buy a better bass, but I'm referring strickly to the USA models. The Skylines are not bad basses and I'd buy one before I'd buy say, a USA Fender, but you can count on the fact that as we speak I'm practicing patience and saving my bread for another Deluxe 55-94.
There's a mojo to a new USA Lakland that I can only compare to holding a new Sadowsky in your hands (Sadowsky's not my sound but that mojo is unreal). Specs aside, there's an air of refinement that you just never thought you could see on a bolt-on instrument-- the edges are cut with a rounded edge as if by hand, the neck pocket is perfect as if every instrument's neck was cut specifically for the body to which they were intended, there is no gap between the edge of the pickups and the routes they fill, the neck feels like tung-oiled silk and the fretboard shines as if it were cut by a diamond, the woods' grains just stare out deep and dense on the front, back and neck of the instrument, I could go on for hours but it's starting to make me drool.
What I'm trying to say is that is a USA Lakland cost twice what it does now, that's what I would pay. I'm actually quite impressed that you can get one on the street for $3100 when many other manufacturers of similar build and quality and thousands more.
