beneathedarkness , i'd be interested in having a look at some of those pics if you still have them. thx!
hi johnniespring , yes i do know the firebird one is a hum, well actually it's an mini hum that doesn't have high output. This is the reason why i thought about it (even tho i will certainly favor a 2nd p90 instead) and also because i mainly use the neck pickup most of the time, so i thought it could be interesting to have a more slightly more powerful pickup for certain parts. I also saw that particular setup on neil young's guitar and it has intrigued me.. i'm pretty sure he uses it for the same reason.
Anyways, as for the mod itself, i think you are right, it doesn't sound too complicated. Still if i can't manage it myself, i could have it done by a local tech.. i'll see..
thx for your comments and answers
