"Customer service" is for people who don't read the product catalogs imo. I wouldn't expect anyone with customer service to have an answer to your questions as they are focused in the design not general product information.
theyre an interesting bunch over there. its kind of just my general interest in pickups that has me curious. with my own dealings with the custom shop, i wouldnt be surprised with any reason they chose. they can be artsy bunch like the luthiers. dont even think about getting a meaningful answer out of customer service though. ive gotten straight up wrong info from them.
