That pickguard went to Aussie Mark. I have a plank of an Ibanez Ripper (which had a tort guard and two rusted green mudbuckers) awaiting rehab though. The maple is discolored in a few areas on the neck so I'm not sure what to do with it.
As for the SB400, with a slightly lighter set of strings the neck settled down and, satisfied with the action, I moved on to other things. I still don't know whether the truss rod is actually broken or only that it can't be adjusted any tighter (two washers already having been installed). I'll eventually get around to painting and customizing the bass (new bridge, but the pickups stay; I like how they sound), but the EB3L gets the Les Paul treatment first (pickups and bridge off eBay a few years ago, along with a cool headstock overlay off eBay even longer ago). I'm thinking the Warwick bridge might not work though. On a short scale it'd fit, of course, but on the long scale I don't know that there would be any room left for the tail piece at the end of the body. If not, I'll get a the chrome Hipshot 3 point replacement.
