Well, the 1/2 inch space is juuuust enough to pop, but you have to be more conscious where the hand is landing when you transition from the regular finger playing to poping or your index finger will hit the pickup. One solution is to just slap and pop between both pickups. That would be over the middle dummy pickup. It feels awkard at first because its not my normal playing position. Playing a musicman or pbass is extreamly easier when slapping and poping because there is so much space to play with. The Series 1s seem to require more presicion playing but when it finally becomes muscle memory of finger placement, its just as easy again. I enjoy my series 1 and may keep it.
