Re: Will this work and for what? G&L INVADER
I have a G&L Invader and love it, and it's the one guitar I'm still experimenting with pickups on. It came with a trem JB/hotrails/hotrails. Mine is mahogany/maple veneer, with a birdseye maple neck/rosewood fretboard, Floyd. The hotrails neck is perfect, don't change that! I'm using an Am Std strat middle pickup, and am still figuring out the bridge pickup. The JB is too dense and midrangey for my taste in that particular guitar, so I'm probably going to use a C-5 trem, Custom, or Screamin Demon. On a swampash/maple G&L Invader, I wouldn't use a Duncan Invader.
I'd probably try a trem CC first. The other two pickups you mentioned should be fine.
They come with US Duncans, so you may not change anything. I'd probably swap the JB for a CC, tho.
