Does anyone ever look at the back of the drivers inside the mesh of their Grado's? Im trying to figure out why they place a black goop on some models and not others.
Its black, hard, kind of bubbly looking, and its covering one of the 3 holes in the back of the driver (holes are aranged ->(O- O -O) Black goop covers the middle hole on the button-top of the driver.
So far ive noticed this on the RS-1's, MSPRO, RS-2, and ive just seen it on a modded SR60 or 80. I have NOT however seen it on my old SR225's, MS-1's, SR325i's or some SR60's and 80's.
Seems like an aftermarket mod John does to some of the drivers after production.
Anyone else know anything about this?
