I'm looking for opinions, and would welcome any! I have a commission to build a twin neck 5 string bass. The criteria are: Both necks to be through necks, laminated maple/mahagony/maple/mahagony/maple, the bocdy is mahagony. The necks are standard 5 string (B,E,A,D,G) and tuned an octave above (piccoloa bass). Single truss rod on the piccolo neck, twin on the basss. Both are 34in scale length, ebony fingerboard inlaid with silver/abalone/MOP symbols. Top nut widths are 46mm (1 5/8ins) So far I've select Fender (almost) style headstocks (mirror images) as the heads on most twin necks do interfer with each other. The questions I'm still stuck with are: What pickups and how many? Which neck should be the top (bass or piccolo)? I know these seem like fundamental questions that should be sorted by the client, but he's left it up to me? Help??????
