The pickup is sitting high, I loosened it off a bit because it is not sitting square, you are dead right re the loudness of it the other obviously isn't so loud, I am waiting for that foam to come to pack out one side to square it off before tightening down, there is still a very small amount of bow, I slackened it off last night about 1/3 of a turn, a 1/4 didn't do much.
The pick up in the pic is pressed down as low as it will go, got a funny feeling it is sat on the wires from the 3 way switch, I taped them off to one side, might have to also open up the outlet for the wires too as this wasn't as far down as I thought it could have been.
