Which version of the '71 would you like? The '71 Student has a forearm contour, the '71 Limited has a flat top, but is fully bound, and the '71 Trella has the same features as the '71 Limited, but with a carved top.
There's a pic of what I'm talking about over there ---------->
Tip from your pal Sully; don't bother adding locking tuners if you've got a locking nut, unless you just can't live without them.
Your Sully will come stock with Habanero Pickups (made in USA by Grover Jackson). They're excellent, hand wound in the US, very responsive, and can handle all styles. I cannot recommend them enough. If you prefer another pickup, that's okay, too, but keep in mind that all '71s have dual humbuckers only.
Your '71 comes stock with one volume knob, one tone knob, and a three way toggle switch. If you like, you can opt for dual volume knobs (no tone). Of course, you can add coil splitting via push pull knob, too.
If you want a trans finish, don't choose these options
If you want a solid color, don't choose these
By default, all bolt on necks are finished in tru-oil. This can be done on set neck or neck through construction as well. If you prefer a neck that's clear coated, that's cool too.
