Neck swap - Squier deluxe Jazz Active 5
 

The squier deluxe jazz(V) 's neck is much wider than you standard 5 string jazz. I'd like to change the neck from it's maple/ebonol to a snappier maple/maple. Just don't know if theres a neck which will work..

the string spacing on this bass is 19mm. thats bigger than the usual 16.5-18mm, on a five string. is it even possible to swap the neck?

???????????

Very possible. Someone here put a MIM Jazz V neck on a DAJV body. You could also go USACG or Warmoth, I imagine.
