Hi Samatizer.

Agree with comments already posted.

Only thing I might do differently would be to create a channel under Bridge Pickup to allow cables to sit below 'sea level' and clear the edges of pickup housing. If you are nervous about drilling out the rather high-set cable hole to control cavity maybe a very fine chisel could be the answer. You only need to enlarge the hole down to base of the bridge pickup cavity but a bigger diameter on the way through would be ok too.

As for neck pocket and scale length it looks like your kit has been pre-drilled for the 3 point Gibbo style bridge and recommend loosely placing bridge in correct position, then measure 34" from top of G string saddle to inner side of where same string goes through the nut and see how well the neck sits in pocket. If it looks like a bit of reshaping is required go slowly, but if it sits OK you may just have to live with a small gap at end of neck pocket.

Scale length is most important and 1st place to start with trying to figure out what to do.

Cheers, Waz
