i noticed a curious thing... the bridge unit of a warpig calibrated set i bought some month ago (actually my first BKPs!) has a resistance of 22.1k (the same declared on website) (no, i didn't measured it, i don't even know how to do it and i don't care this much... i simply read it - handwritten - on the technical sheet). recently i bought another warpig, this time bridge only, and the sheet says it's set on 20.1k.
could it be just a writing error or is it possible to have such different DC values on the same pickup model?
