I mean who the hell would get anything sound-based when it's described as "flat?"
To me, it just seems that no frequency stands out more than the rest, so it's not super-bassy, not middy, not a trebly nightmare. It's a very evenly voiced pickup, with no really dominating part of the spectrum. I just wish there were a more sexy way to say that than "flat."
The thought of leaving the tele alone has crossed my mind more than once. I even have saved searches on reverb and eBay in case the occasional aerodyne tele body shows up for a decent price. I'm not above keeping mine stock, but having a 2nd one to mod. I really like the carved top look on a tele, wish fender had more.
But I do agree, the bridge isn't the problem. That P90 blows. That's what started this whole thing, I was trying to figure out if the one in the aerodyne was a shining example of all P90s or just an uninspired throwaway in an otherwise great guitar. I don't really want to just live with it like it is, I'd at least like it to be something I don't hate.
The idea behind the bridge was mostly "if you get this neck pickup, this bridge pickup compliments it really well", but also an opportunity to see what people recommended if I do decide to pull the trigger on a new bridge. One less thread I gotta make later.
Amp and fx? My current amp is a tiny terror and matching 212 I got in a trade. It's not sticking around. All of my recording setup is direct in. Helix, neural dsp, etc.
Or you could just crank it down low and ignore it, or unhook it. For the music/tones you're talking about, you can easily survive without using a neck pickup.
Do you like the middle switch position?
DiMarzio seems to be the company that is making a bunch of their traditional pickups in p90 sized formats. Might be worth just picking one, see if you like it, and if not take advantage of their exchange policy.
It's a utility thing. The pickup is there, there is a spot for it, I'd like to have it and for it to be usable.
And I have never used the middle position. It's honestly not a position I use a whole bunch on any 2 pickup guitar. Usually front or back.
In order to do this, you need to convert to Les Paul Deluxe style mounting. That involves installing a threaded metal strip on the bottom of the pickup cavity. Then you need to purchase the right pickup ring. It has the outline of a P-90 pickup cover, but it is drilled and cut out differently (to accept a mini humbucker or Firebird pickup and its adjustment screws). Then you need spacers, springs, and retainers. Stew-Mac has almost all of this in a kit: https://www.stewmac.com/Hardware_an...s/Deluxe_Mini_Humbucker_Mounting_Bracket.html. You just need to purchase the mounting ring in addition: https://www.stewmac.com/Hardware_an...ates/Deluxe_Mini_Humbucker_Mounting_Ring.html.
