JPMDan said:when it comes to a 7 string guitar alder body is much more balanced than basswood. fingerboard doesnt contribute but its more of what your fingers like. Maple neck would be a great combo with the alder body. As far as pickups if you like his ibanez tone then yes Steve special and air norton but for his newer tone D Sonic and Air Norton pickups. But your stuck with the D Sonic when it comes to a custom 7 string.
Blaze 7, according to DiMarzio, is basically a Steve's Special 7. Also, they do make an Air Norton 7, and it kicks ass.
