Nope, waste of money. Bridge runs $60, preamp?, pickups $99 each.
$260+ in parts and the $150. You could score a complete Tribby for less.
However to build a pickup tester by installing a bridge and routing the snot out of the center to make a test plank? Sure.
May be worth $150 for the neck though. You can't get a replacement Tribby neck.
$.02
Wonder what he built?
