Bolt-on or neck through - what's the real difference?

My first bass was neck through - a 4001 Rick. My second bass was bolt on - an 80's aluminum necked Kramer. While it would seem that an interface like you have on a bolt on is an "opportunity" to lose energy (and therefore sustain), the Kramer had much longer sustain. This was not a subtle thing - I had to learn how to manage that ridiculous amount of sustain in certain places in certain songs - at the end of a song, if we let it ring out, the difference was obvious to everyone in the band. Yes, there was a huge variable there (aluminum vs wood neck), but that example shows that there are other factors that can influence sustain besides the neck joint architecture.

With a well made wood necked bass, it shouldn't matter all that much if it's bolt on or neck through. A bolt on gives you an out if the neck goes South at some point, but if the builder has properly aged that wood and knows how to make a good neck, that shouldn't be an issue with either route.

If the neck has a tilt back headstock, I'd make sure the builder knows how to make a good scarf joint, especially if you're gonna go neck through - that definitely lessens the chances you'll be fixing a broken headstock down the road.

I haven't really noticed much difference, other than playability--neck-through designs supposedly make it easier to play in the upper registers of the instrument (but who actually uses the 24th fret anyway?).

The only thing I can really think of a "benefit" would be the aforementioned post about it being easier to replace a neck if anything happens to it, if it's bolt-on. Replacing a neck-through design is, well...not really an option.
 
I've owned 13 basses in my lifetime - 3 of which were neck through and to be honest I can't tell the difference. My 2 main basses are bolt ons and my acoustic is . . whatever an acoustic is (set neck?) I'm thinking about having a custom bass made and is it worth the expense to have a neck through?

There is, apparently, something to it.

Out of my six basses, three are neck-through, and of those three, my two Carvin's have immense sustain, while the Ric 4003, not as much.

Of my three bolt-on's, all Fenders, they are pretty much the same in the sustain department - adequate, not stunning.

I believe, when it comes to neck-through, it comes down to maker, and the woods used.

Shop around. :thumbsup:
 
I assumed that I was . . as for the Thunderbirds - people are raving about the Epiphone 'Birds out now and they are bolt on.

No, that would be incorrect. The Epiphone Vintage Pro ( or '60s Thunderbird) is multi laminated neck through.
 
I don’t have any neck-through basses atm but when I did, I found the neck/body joint to be more comfortable and easier to play at that spot than a bolt on. Also - if a person wants to replace the neck on a neck-through, that is obviously a much more difficult thing to do than on a bolt on. I’ve found neck-through also feel like there’s more tension on the strings. As far as the actual sound difference? Subjective.
