So, another "work from home" day, and the neck is fitted!
It's interesting - the nut actually seems OK - aesthetically, I don't like the cr@ppy angle, but it does actually work. I might still upgrade it to something nicer, but it'll do for now. I do need a string tree though - the slot for the high "e" is a little too shallow, and I don't want to cut it deeper. No dodgy harmonics though, so there's enough of an angle behind the nut I think.
The most interesting thing to me though is how much this changed the acoustic tone of the guitar. With the Charvel neck, it was always my acoustically loudest and brightest electric. Way louder than my PRS NF3. With the maple/ebony neck, it's a little quieter, but WAY less bright - I've always been a little skeptical about the effect of wood, but everything here is constant, except the neck. I even tried tightening or loosening the neck screws... It sounds genuinely more dark and "middy". Which is really cool! Bright and dark are both great to me!!! The new neck is way chunkier than the Charvel, which is 1980's skinny - I'm sure that's probably a factor too.
The Planet Waves tuners are a breeze - easy to fit, and putting the strings back on was a doddle.
Off to Holiday Music in a sec to get string retainers. Then I'll have a blast on it plugged in, see what that's like. Although I'll be swapping out the Trilogies at the earliest opportunity - way too modern for me - in favor of a nice, vintage-y HSS set.
