I have a Switch 4-string I bought a few years ago. It is actually the first one I've ever had with actives on it. It's an interesting beast, weighty and has some quirks to it. Can't complain about the flexibility of tone with it or the sustain (wow!). From what I understand, at the time I bought it, they were still producing Switch guitars and basses in the U.S. but were looking to shift up to Canada. Wondering if anyone knows anymore history on them. Also, have not been able to find a serial number on this thing. (This could be scary...) Overall, I like the thing. There's just a lot of little questions about it that I'd love to find out more about (pickups, electronics, tuning down without it going out). Anyone with any info, please post. Would love to find out more.
