So I bought this bass used/excellent a while back, and while it wasn't real bad, there was just enough relief in the neck I needed it changed. It was non-warranty and I did have to pay for it, but IMHO, it was well worth it. Here's a pic of the original bass, the only one I have, sorry for the quality:
Ahhh, but there's more...
While I had them on the phone, I found out they offer a trussrod upgrade/option on their basses for not much money, so I figured heck, put it in, then it doesn't matter what the factory setting is, I can set/forget to whatever I want. On these, the adjustment is hidden in the neck pocket, because this is not a seasonal thing. You (again) set it, and forget it. With the trussrod option, the neck is just as rigid and stable as it was before, doesn't move under string tension or enviromental change, but its proprietary design is strong enough to just give enough adjustment to cover a good range of relief adjustment, and it doesn't add much weight to the bass (it does NOT neck dive AT ALL and seems to weigh about what it did before, which is heavy for a Zon, but at least it didn't gain much -- about 10 pounds).
Stop! Don't order yet! There's MORE!
So this past NAMM, I finally got to meat Joe at his booth. I started drooling over the models with humbuckers in there, and lamented that this one was basically just like my beloved redwood top'd model, so I asked about a "humbucker upgrade". At first, Joe didn't think it could be done, but about a week later, he tells me he could, would, and recommended these SD narrow aperature humbuckers like he uses in his Sonus "Classic" models. I told him to "go for it". Which he did.
The results are in... just got it back today, played it, and it's AWESOME! Sits right between my Custom and redwood Sonus tonally, and gives me another humbucking Zon to choose from at "nasty" venues with lots of electrical crap going on. Ironically, the relief is dead perfect on it now...
Hope you like it... put pictures of my redwood Zon with it, so you can see "sorta'" before/after diffs, and also my Custom, so you can see the how it's diff as well...
