Bought this on this site about a year ago from Sharkfinger.
This bass is very lightweight at just under 3Kgs and medium scale. It has a natural body (alder or basswood) and satin neck. Headstock has a dark wood veneer. There’s a very small bit of buckle rash on the back. Pickups are probably the original ceramic. All passive controls are volume, blend and tone. It has standard BBoT bridge and 38mm nut width.
Would prefer pickup from Farnham, Surrey, but can ship for another £20.00
