I liked different things about each, but I think the one I was most happy with was the Celinder - it just absolutely nailed that 70s jazz bass slap sound. In terms of 'dreams' it absolutely was the exact sound I had in my head for that particular style. But I was never particularly keen on the jazz body shape. The Smith 5 was amazing and sounded perfect, but I din't find 5 strings as natural as 4s. Both these two were a bit tricky in a band situation, where each got a bit lost in the mix. Possibly something I could have addressed with amplification but I felt they were excellent studio instruments.
The Alembic 6 was way too heavy and I am even less comfortable on a 6 than a 5. Plus you whit that out and people think you're going to be absolutely shit hot, so it was writing cheques my body couldn't cash.
The Vigiers - had many, but the faves were the Excess and the 1988 passion, which was my number one for a looong time, having seen off everything else I have had in between. But I feel like it doesn't suit what I do now, my tastes and style have changed and I no longer feel like it's 'me'.
The Smith 4 was fantastic but I couldn't get the setup as nailed as I would have liked (I used to obsess over that more than I tend to now).
Stingrays are great but I found them hard to develop a 'voice' with - they sound lovely but somehow I never find them very expressive, no idea why. I keep thinking I'll try again.
The first two 'high end' basses I owned were a Pedulla MVP and a shell pink 57 reissue P bass. I certainly hadn't developed my tastes enough to appreciate them at the time, especially the P bass which I wish I still had. The Pedulla was amazing and sounded great, but I never 100% loved the shape. I think I sold that for a Marleaux.
Looking back, though, I don't think I've ever really lost much money along the way. Apart from that initial purchase of the Fender and Pedulla, I think I've generally traded my way through different things and loved the process. Probably lots more to come, but I've arrived in a happy place!
I think it's true what you say about sounding like you no matter what you play, but the bass makes you play a certain way, too.
