Starting in GHWT,there are now customization for drums,mic,and bass(as well as guitar.). All of them(except for drums)are fake made instruments(though some Guitars are desghned simarily to real guitars.). They must be bought(until GH5,when there is no money and everthing,unlocked or not,is avalibele).In GH Metallica,Van Halen,and Areosmith,they are all real guitars by the band.(In the case of GH Metallica and Van Halen,where it is also the drums,mics,and basses of the band.
