Hello.*
NathanJ,
Thanks for the inquiry...
Musicman:
4string 19mm or 3/4"
5string 17.5mm or 11/16"
Elrick:
4string 19mm or 3/4"
5string 19mm or 3/4"
(Adjustable side to side spacing on saddles)
Going from fretboard to back of neck:
Musicman 5string necks feel more substantial to me. The Elrick's have flatter necks on the 5strings than the Musicmans do. Not saying one feels better or worse (that's up to you & the voice in your head that you argue with

)
Feel free to shoot us an email and we can give you any more details you might want.
