Maximum Overdrive: the case of Guitar Hero's missing effects pedal

Little known factoid: Harmonix had always intended to include a packed-in pedal with their very first version of PlayStation 2's Guitar Hero, but were denied by an obscure Sony clause that limited each game's number of peripherals to just one (the one, in this case, being the guitar itself).

Four years later, and finally -- I have suddenly learned via FakePlasticRock -- Mad Catz has filled the void with an Electro-Harmonix (no relation) branded Rock Band 2 version which may be the first third-party accessory I purchase in as long as I can remember (though FPR also notes that, with an extension cord, your standard-issue Rock Band drum pedal works in a pinch [!]).
