neck fit pros/cons

Good Day.
I am building a psudo thinline tele to get my feet wet.
Things are moving along nicely, well best it could be for a first go. I did not build the neck as my previous necks have needed some heavy fret leveling, a little to much really. So I bought a neck, short story it sucked, but I had already cut the neck pocket. So I bought another neck, a all parts licenced Fender neck. So now is the problem. The fist neck I had fit really nice and tight. Now the fender neck is a little loose. The first neck I could press it in with my hands and it would stay put. This new one is loose enough it has about 1 mm all around it.
So the question is what to do about it. My understanding is if I fill up the gaps with glue the glue will dampen things. I could fit in one or two pieces of thin veneer and have less glue in it. I have done parts casters and the neck pocket had been big like this and just bolted in the neck and not worried as it was parts. So is this really a issue, any thoughts on this.
Cheers Ron.

I personally don't think it's as much of an issue as people make it to be. But this is only my humble opinion. The reason I say that is I've seen 6 string cigar box guitars with the Fender style neck only bolted on with very little or no wood touching the sides of the neck. Those guitars were real screamers. As long as your neck is bolted on tight, I bet it'll be very resonate.

Other than aesthetics, I don't think it makes a difference.

As long as the neck is bolted on tight and straight, it makes absolutely no difference whatsoever - unless you either have an issue with the cosmetics of having a small gap, or your unconscious believes that such a gap affects tone, sustain, or playability. At which point your psychology will likely take over and you will hear and experience all sorts of differences and deficiencies right up until you get rid of the damn thing.

Thanks for taking the time to reply, and reassure me that common sense rules.
At this point the crack will be easier to live with than the crappy hard to play neck, seems playability/sound trumps good looks, well for me anyways.
Cheers Ron.

Are you going to have a pickguard?? I was able to cover a similar crack with the pickguard.

Good luck...

I had not thought of one but yes that would cover the joint, thank you

My MIM had a lot more gap than that and it played fine.
It makes no difference to the sound or playability and a wee bit of slop just gives you a bit of leeway to kick it sideways a bit upon assembly to ensure the strings are parallel with the board. Unless it is absolutely perfect, too tight can be a bit of a problem in the end. It looks nice though I suppose. Secretly of course I wish I could make mine better but fine skills seem to elude me. I lean more toward function than looks.

Unfortunately that statement fits me too...until I get a few more builds under my belt.
