I had to cut the rubber seats, to shape them in a way they fit with my tom rim. Nothing special, and i believe its is to be expected with a generic product like this and all those different drum makers.
Also I had to add some nuts to act as spacers on the screws of my toms and some duct tape to act as a gasket to prevent the 2 metals slip.
Again, I was prepared to do some minor adjustements, because its an item that can be used on numerous drum makers, you cant expect it to fil like a charm on everything.
Apart from that, the tom's waight and hits it takes is maybe a little much to handle but after months of excessive rehearsals and gigs, it still does its job well!
Im not sure if it affects sound, I bought it for psychological reasons :) I cant remember the old sound anyways.
