I had two bridge model Invaders in an old Jackson Kelly XLR (I believe the body was poplar, similar in tone to alder), and they sounded great. Lots of low end, but still pretty balanced sounding overall.I emailed the guy that custom designed his guitar again to confirm and he said that he did have a bridge invader in both positions. Is the issue that it’d be too hot, too flubby, or just really dark sounding? I wish it wasn’t a pain to resolder otherwise I’d like to try it myself.
