Hey Guys,
I didnt want to tell too much as I dont like when people write pages of how great an instrument is that they are trying to sell..
but since you asked :-)
I really like the neck. It is fast, and not thick at all, but due to the high quality hardwoods used, it is the most stable neck I ever had. The String spacing is 18.5mm.
Whats also really comfortable is the curved top/body of the bass. It hangs in perfect playing position, and also its really comfortable on the right hand.
I think these basses have a lot of similarities with the pre-gibson Tobias basses. Sound and feel wise.
Check out Orin Isaacs, he has a couple of Vadim's Basses:

All in all I just love the Passion and Soul Vadim puts into his Basses. I think thats what is so unique about them. You dont find this a lot these days.
