Heres a custom SG design build I done some time ago.
The body is solid New Guinea Rosewood with a Maple/Mahogany/Maple/Mahogany veneered pick guard and Jackson J-10 humbuckers.
Both pickup cavities are fully copper shielded.
The Rosewood has really awesome feature in it and holds great sustain.
All Vol/Tone dials have been pearl pointed and ive used an all metal toggle selector switch.
The neck is a reworked Maple Gibson "Maestro SE" that ive inlaid the headstock and heel with in matching Rosewood and Atlantic pearl.
Gold Gotoh machine heads also.
The bridge is a legit Gibson Tune O Matic with a Gotoh tail piece.
All wiring is traditional cloth bound. Only the pickup leads and earth wire are plastic shielded.
Ive also kept a full set of pics during making the guitar so you will see exactly what is where, why and how.
Ill ship out to anywhere in Australia at no cost (in a custom made crate, not a cardboard box)
All up it took about 2 months to make and id like to get around $900 for my efforts.
Im not a buisness, but ive been making guitars and components as a hobby for about 20+ years now and would eventually like to start something commercial of it..... eventually!
