There are only 27 basses like this in the world. Made in Puerto Rico by Fabregues. Swamp ash body and ash/maple neck with 2 graphite rods. Bartolini 9v. preamp and soapbar pickups by bart. too. This is a photo of the circuit cavity exposing the battery and preamp and wiring. For photos of front and back, email me. Sorry the photos are too big for TB. I also have an ART Nightbass III Studio Edition rack mounted with the X-12 midi floorboard. Dont have pics but you can do a search on ART Nightbass and all it's info is there. Too much!!! Bass goes for $1300 or better offer + shipping. Fx goes for $150 or better offer + shipping.
