GHWT instruments on RB1

I imported the UK version of RB1 a long time ago, but because of shipping cost I didn't get the instruments. Now the RB1 and GHWT instruments are out here in Australia (or about to be) I want to get a new guitar and drums and mic, but I don't want the old RB1 stuff.

Since I will be doing most of my playing on RB1 because of the DLC. How will the GHWT instruments work for RB1? Especially the drums, how will they work since there is one less drum pad?

it's like there are almost the same colors so the one that are not on the game is turned off
