i already have the white one that came with my guitar hero ||| but sometimes the wammy doesnt work. are there better guitars out there?

Yes there will be in fact new Guitars coming out in stores. But Im not sure when they will be out. If you don’t wanna wait for the new guitars to come out in stores, just buy the regular Guitar from any store that holds them in stock. Like Gamestop, Target, Kmart, Best Buy, etc.
