I only have significant experience of one luthier, Alan Cringeon of ACG.
Alan's designs are distinctive and that gives his basses a brand identity. I, like many others find his range of shapes covers a wide spectrum of tastes and the Harlot wins it for me every time.
If you go to Alan and want something that's distinctly someone elses design then I suspect he may point you elsewhere, and why not he has to spend many hours crafting the instrument that'll carry his name and reputation. He's not a jobbing builder but a guy creating his own concept.
There's been, imo some crap written about 'furniture basses' and 'coffee tables' but if a bass is made from wood why not celebrate the innate beauty of it? Alan will be the 1st to say 'a bass is a tool, go out and use it'.
Which brings me to the next aspect of his basses. He takes care to research, source and experiment with his own ideas when it comes to pickups and electronics. He is constantly trying out new types of pickup and refining his pre-amp. He doesn't buy in stock gear and plonk it on.
I have owned far too many basses (probably over 40 ) and my ACG Harlot surpasses them all in every respect. I'm not just bigging this up because I think Alan's a fine guy (he is) but because in terms of playability, neck profile, tone, weight, balance and ascetics it's simply awsome. It'll be at Harrogate if anyone wants a go, slappers keep away
