Hey all, I just did an overhaul on my 2007 signed Jem 7VWH. Everything worked out great and I am very happy with the results. If you have any specific questions or comments I will try to answer and help. I've seen virtually nothing on sustainiac installs especially for Jem front cavity so I though I would offer. I have a small pic documentary of the changes and mods. Listed here: New pickguard I designed. Black screws replace the old gold which were turning silver. Black back cover plates and truss rod cover. Copper shielding for control and jack cavities. NOTE * You DONT put shielding around pickups with a Sustainiac install. New gold custom dragon knobs. KGC brass sustain block, KCG Killer compensated claw. Silent springs and brass trem block. Locking bridge pins (not standard with my Edge Pro) Bare Knuckle Nailbomb in bridge position. Sustainiac installed with battery cavity. The original look. Original pickguard (with Fishman midi pickup which is also super cool) New look. Custom knobbies. Rear with new brass goodies. Front cavity routed to fit sustainer board and new push pull pots. Shielding. Semi wired guts and shielding on pickguard. Rear with new battery box and covers.
