If its an '05 it might be a custom order. Alot of the older models can still be purchased. An '05 bass with a brass nut would not be standard in my knowledge. Would either be a later addition or a custom option. The contours near the neck joint would either be a custom option or a later addtion.
If that is standard it is very unique. My guess is either custom order or someones project bass. ie. Addtional body contours added and maybe a neck swap from another warwick bass. Maybe a FrankenWarwick.
Just bought a bass from Gareth, it’s in top condition, good communication throughout and shipped here at top speed. A very good and efficient guy to deal with.
Gonna have to speak this guys praises again. Completely painless transaction. Kept to his word and made it very easy for all. Even collected the bass from me.
Won't mention what he was playing though. Your A.L. secret will be kept. Haha
