Re: set neck/bolt on
Dint Richie Blackmore had some starts with 4 screws and glue and some just with glue? I like minimum glue and minimum paint, burst finish, maple neck strats, you get the best violin tone and articulation. For some however it might be to twangy/bright.
Ritchie Blackmore had a few of the bad 70's strats which had the poorly routed neck pockets. His solution was to glue the neck in place. He'd put epoxy in the pocket then screw the neck down.
EVH had this problems as well. Through the years he routed his neck pocket to accomadate a 2 1/4" Charvel heel. He switched necks alot. When he went back to a standard 2 3/16" Fender size heel, he stabilized the neck by placing 2 extra screws under the neck plate.
I have all 3- a set neck Les Paul, neck thru Jackson, and many bolt ons. A properly constructed bolt on has all the sustain and attack of set neck and possibly a neck thru.
What people don't necessarily take into consideration in the strat/les paul sustain debate is that the Strat has other factors, other than the bolt on neck, which decreases sustain. Immediately, I've found the pole pieces on strat single coil pickups pull the strings too much, decreasing sustain. The Fender Tremolo compared to a Fender hard tail or Gibson Tuneomatic contributes to a decrease in , even if it's blocked. If the strat neck is improperly shimmed that'll result in a decrease in sustain as well.
The sustain on my Malmsteen strat was good, but increased through the roof with EMG pickups, which had less pull. Sustain is comparable to my Jackson Soloist nect thru. Both are made of similar woods.
My Ernie Ball Music Man Axis is bolt on witha Floyd, and sustains as well as my Les Paul.
Tonally, bolt ons have more attack and are clearer. Neck thrus can be a bit compressed, and set necks fall in between.
The advantage with getting a Strat, Tele, or Fender variant is the necks and bodies are easily and cheaply changed to suit your tastes or needs. It can be quite expensive to change a neck on say an Ibanez or Jackson since they have to be custom built. On neck thrus or set necks you're pretty much stuck with whatever specs are on the neck.
