Bolt-on Ric necks

[weemac]

Some more reasons for the perceived "Set neck = more sustain" is that:
1 Set neck guitars usually have either Humbucking pickups or hoter singlecoils (P-90s) with their compressed sound will add to the perceived sustain.
2 Bolt on necks always seem to have more attack. Starting with a louder note will seem like the string dies earlier as the volume drops
A set neck has less attack but in turn seems to have more sustain as there is not as much volume to decay from.
ie less attack (smoother) gives the impression that there is more sustain.

My bolt on (six bolt extended neck joint) Jack Spira 8 string bass has almost unnatural sustain...

Some exceptions to the rules are:
Steinberger L2 had not a lot of punch but unearthly sustain.
Waterstone tp-12 with its 32" scale and hollow body and set neck should not be the sustain monster with thumping punch that they are, however it may have more to do with the octave strings egging the root strings on a bit...

My Rick 230GF has a big sustain en bite, but its like a fender made from Maple, the body the whole neck. Gibsons are made from mahogany so they sound different and also the sustain is different.
My Gibson has a longer sustain but the Rick has a stronger more aggressive kind.
But compare them is not easy they are two different kind of animals
