Whelp, it has a DGTC on board...and they love that $hit, so it must, right?
Lets add up some costs:
Dingwall Combustion (used): $900
Darkglass Tone Capsule: $170
Dunlop Strap-loks: $14
Custom pickguard: $80
First de-fret: $200
Luminlay: $136
Neck inlay removal-clean up and re-inlay, refinish, level etc: $530 (a bargain for the amount of actual work)
Graphtech bass piezo preamp: $130
Graphtech Bass piezo ABM bridge saddles/pickups: $110
Customization to existing ABM saddle hardware, modify body, customization to Graphtech hardware, design/implement new electronics setup for both pickups: $290
Meet the $2560 Combustion.

But still, given new Combustion pricing and the 'options' I've chosen... Is this worth $600 more than off the shelf? I think so.
