I'm thinking of replacing the JB in one of my alder Jackson DK2Ms with an Invader, as I've had excellent results with Invaders in basswood and ash guitars. I have other JB-equipped guitars (all basswood) that I could put the Invader in, but I already know how that sounds.
Anyone using an Invader in alder?
I had one in an alder (multi-pieces) body of a Squier Stagemaster 7-strings and it was all kind of awesome. Mucho bite, tightness and attack. In one word : agressive.
