Yup.
Hmm... Some dude online, you should check it out => LINK
I've still got the Invader I bought from you Kac, in the box. (Well, I traded it for a white one, but regardless, I've got an Invader, Brobucker, and previously installed JB all chilling waiting to be installed in something)
Bought another Invader myself. Martin thanks, now I have a twin to my other Invader Zebra. First thinngs first is the mushroom caps come off and hex poles go in. I've tried all the mods (1 meg pot, the mod in this thread, wired directly to the output jack) and they all still seemed too muddy for me. The hex head mod is the best mod IMO for this pickup. Try it if the mod in this thread doesn't give the desired results.
KAC I ordered mine online from Mcmaster-Carr. It's probably $10-$12 for a box of 100. 10-32 threads 1/2" length black oxide, you should try it in addition to your mod.
