So I have a jazz that sounds extremely good for busy metal arrangements, but as soon as the guitars play in higher register, the sound seems to lack oomph. This is obviously due to cancelling properties of two pickups fully engaged, since the neck pickup solo'd packs way more punch than n and b combined. So the solution as I see is this - put a punchy P pickup JUST below the neck pickup and engage it when additional punch is needed. Would this work or the P needs to be in EXACT position (of the neck jazz pickup) for this to work? Physics obviously suggest the difference will be there, but how big, is the P pickup just below the neck one on jazz punchy enough to do what I need?
