Re: OK to flip a L handed pickup to make it a rightey?
^^ upcharge: AFAIK no.
Also, not every lefty is enterprising enough to get the idea to flip it around. So you flip it at the factory and call it a lefty, avoids confusion and lowers the rate of returns. I think the main difference is where the wires exit on the baseplate, but I haven`t had one close up in a few years.
There may however be some other technical difference that eludes me at this time...
