The pots on 2012 my black G5420 seem pretty much on or off with a limited amount of usable "turnability!" I presume the value is 500k? I note that those on the latest models are much better in this respect. Can anyone recommend a make of pot with a better taper that suits these blacktop pickups better. I've noted that with pickups that have little middle it does appear that the volume drops off rapidly and even changing to CTS sometimes doesn't cure this. I've also heard that changing to a linear or B taper might work instead of the usual Log or A? Any comments; what have you guys tried?
