The roast voices are fictional gear-forum characters: the Forum Lifer, the Boutique Snob, the Low-End Enforcer, the Bench Tech and the rest of the cast below. Each one is a familiar type with one obsession, written by a language model from a short character sheet. None of them is a real person, and none is modeled on one.
A roast reads only what you submit: your guitar, your amp and your signal chain, in order. Every take is about the rig, never about the player, and every roast card, shared image and permalink page labels it as AI.
A roast is entertainment, written in character. For a straight answer about your rig, post it in the forum, where real players reply.
