Now that the ISDs are in the (US) shops, could someone tell me how tall it is? I'm planning to take advantage of the sales and get some pluck foam, but not sure whether I need 3 or 4 inches to fit.

Thanks in advance.

Its a little over 3 inches. Yo might want to go with 4 just to give you some air space.
