Yeah.. I deff agree with Mike.. You only have 2 options.. If you build it for yourself, your going to be greatly disappointed because you cant buy a pair of EMG's, bolt them onto some wood, and expect the Electric Wood sound.. And if you build it as a knockoff to sell, you'll be even more disappointed with trying to pass a fake onto an actual buyer. Theres a reason you cant find these @ GC.. Why are you even attempting this? If it were easy to replicate a Wal, don't you think there would be more of them around?? Don't be a Pin-Head!
My advise to you is this.. 1) Get a Job.. 2) Save your $$$.. 3) Re-Think your Plan!!
