I think I have the specs for this (although no birthday) from old threads.
But I'm wondering what info there may be concerning later trips to the factory?
It looks like the Q switches were changed. But anyone could have changed those. The originals of that era were silver, and not black. It's hard to tell when I zoom in, but it looks like it still has the original 5-pin Cannon connector.
This bass was upgraded in June of 2001. There's no note of changing the switches, but it may have been something that dad just did when he did the upgrade.
