Great to see some traffic on this topic again.
I'd put my SWB-1 away for a while, and when I brought it out again recently, found that the trussrod needed quite a bit of adjustment due to the extreme change in humidity. It seems to have handled that okay.
More seriously, something weird is going on with the volume pot on my bass. It's been a bit scratchy since I got the bass, but now it seems to be cutting in and out entirely, and the tone seems to be affected too. A few days ago the signal dropped out completely. I took the back cover off to look at the electronics, found nothing as simple as a loose wire, then plugged the bass in again and it's working okay. Aargh...intermittent problems are the worst!
I have to admit that it's also possible a cable was at fault, but that can't be it entirely.
Meanwhile though I may just upgrade the electronics in general, as that pot is always scratchy and the pickup selector is, too. Also I'm not sure the grounding is all it should be as the 60hz buzz changes when I've got my fingers on the pots.
Bass feels great though...no regrets!
