My bitsa P bass. Body was £20 off eBay, no idea what it was originally but it's solid wood and weighs as much as a car. Neck was from my beaten up old Squier Jazz (yes I added the decal, sue me). Pickup is a hot Wilkinson off eBay, a tenner I think it was. Bridge was a fiver, pickguard was about 20. EMG active 2-band eq came from my spares box, had it for years and can't remember how much it was Vinyl pretend-MOP neck blocks were a fiver or so. Total cost, not very much at all, but it plays very nicely and sounds thunderous. I might get round to adding a J bridge pickup at some point. Shame it's so fecking heavy.
