I am selling one of my incredible SIB Fatdrives. This was the one raved about by David Labruyre (John Mayer) in Bassplayer. He says he never runs his basses without it and I am inclined to agree! It adds a ton of fatness to any bass amd eliminates some of the piezo quack or high end sizzle from hotter pups. It adds a lot o booty to anything plugged in. This is the blue faced model with the tube. Comes with the AC cord, etc. 200.00 and it is yours. Check out on the shining reviews on this website!
