I'm very sensitive to bass setup. On every bass I've had I try to get a pretty much flat neck (no relief) and seriously low action. If the bass can't do that, I can't get used to it and move it on.
Series 2 Vigier basses are built to be almost flat whereas the series 3 with the 10/90 neck have a touch more as preferred by most players. I find it a tad too much so I did find the lack of adjustability an issue but then again the fact that they don't move is also a huge strength. As a result I think companies like Modulus and Status added rods to give the customer the belief that they could in fact adjust the relief to there preference, although adding truss rod arguably has sound and rigidity implications which go against the whole idea in the first place. I love the way Vigier stay making what they believe in and concentrate on delivering super high quality idiosyncratic basses. They've obviously expanded the range to cater for those who can't live without a jazz -ish shaped bass but there core range remains steadfastly individual and awesome.
