Argh! Tricky! I really appreciate the request for advice Rob. This is my old ray he's got so I know exactly how good it is and it's bloody marvellous and should appreciate a lot when the Market recovers. I'd err on the side of the vigier. It's a new string to the bow and I think sometimes vintage basses are a bit iffy to gig lots, and it may start to need tlc. Also knowing how much you like the pimp ray you have if the old one dosnt work out the chances of finding another piezo matching headstock sparkle ray arent too high. The original retail on that sucker was 1700. Then again if I found a '76 jazz in sonic blue with maple, I'd prob sell my soul to Satan and not look back !! Also why us the bass much cheaper than usual?, sometimes a worry.
Yup I reckon I'd steer vigierwards. But hopefully whichever you choose will work better for you than your luck has lately lol!
