Fender pbass 5er Electric Blue (Nitro Finish) Sadowsky pbass pups Nordstrand Humbucker Sadowsky preamp Tort pick guard custom wire job (explained) high mass bridge Fender hard shell case I'm posting a diagram that helps explain this bass and its wiring. The first knob is a volume for the front pickup and a push/pull passive/active, the second knob is a pan between the pups and humbucker, the third one is cool because it is the humbucker volume/ coil tap for the humbucker, then the switch allows you to select the coil on the humbucker when third knob is pulled out, the forth knobs are stacked bass/treble boost. This is a really cool bass but I am in need of some cash so its up for sell, but i will say this bass IS LOUD and very versatile. with that push pull coil tap you can make this bass sound like a true single coil pj or you can have the humbucker using both coils and it sounds like a MONSTER. This bass does not disappoint. Its very big and very loud, especially with the electric blue nitro finish. [DEL]$2000 shipped[/DEL] $1800 Shipped Cont. U.S. ONLY. or best offer.
