Guitar Hero Classic SG
$39.99 at

This is the one that started it all, black with a white pickguard for the first game, and now palette-swapped to red with a black pickguard (the "Cherry" finish) for Guitar Hero II. It does ꦦhave a cord🌠, which is a non-plus, but it's certainly reliable.

This is the standard by which all other guitars will be judged. Styled after the real-world Gibson SG (part𓃲icularly the new color scheme), with five responsive buttons, one flipper, a solid feel, bumpy start and select buttons, and an average tilt sensor inside.

Interestingly enough, Red Octane's official site appears to only sell the black and white 🍌model, but will guarantee you the Cherry finish for $49.99 (ten bucks more).
