the neck nailbomb is like a heavily underwound version of the bridge model
a lot brighter and very scooped and uncompressed
it's very articulate and twangy, but it's not like a hot paf or something
I could compare it to a duncan '59 (regarding the heavy midscoop) , but it's louder, a lot treblier and more focused than that
I could use that for funk or power metal solos, but I really didn't enjoy it for my styles
I think it was the only bkp model I really didnt bond with at all
I think the neck vhII would sit way better with the bridge nailbomb
it has a similar low mid thickness to the bridge nailbomb, open midrange without going superscooped and a nice sparkly top without getting trebly
like a big sounding overwound paf
the neck cold sweat is about as hot as the vhII, but has a different voicing
lot less bass and low mids, more center and upper mids
still not a middy pickup, but the mids sound more dense and less open, and has a slightly better articulation
both vhII and cold sweat would work pretty well
if you want a more classic sound like govan's, the vhII definitely does a better job at that, but for the regular dimarzio-like modern prog sound like DT and SX, the cold sweat may fit better
