Just showed up here and seeing this Zon thread I wanted to post some Zon Love (that said, I'm not reading the entire thread). I hope the OP received his VB4 and loves it as much as I love
View attachment 7087099 my VB5. It's a set-neck, swamp ash body, natural matte finish. I received mine direct from the Zon shop in 2006 and this one will never be sold (by me anyway--all bets are off if I croak and my wife sells it!).
I really do love this bass! It is so light and yet sounds huge! Mine has a ramp between two the Bartolini pickups and has mostly worn flats all it's life (I love flat wound strings: mostly TI's but recently had my tech install a set of LaBella Low Tension Flats, and they're verry niiice!).
Communication with Zon was good. They are hard to get in touch with but I usually got them by calling the shop. I recall ordering the bass in the fall of '05 with an expected delivery by Christmas of that year. Delivery wasn't until March of '06 however because Joe wanted to install a truss rod in the neck. I no longer recall the details as to why other than something occurred with another customer's bass that led him to believe it would benefit from a truss rod. It has never needed an adjustment tho'.
Just a fantastic bass IMO!
Much love for Zon!
