What does each cheat do in Guitar Hero: World Tour?

Question

I can easily find a list of cheats for Guitar Hero: World Tour by just searching the web. However, even after unlocking so many cheats, I still don't know what they do.

Some cheats are quite descriptive (the one that unlocks quickplay songs, or the auto-kick one), but others are not that obvious (Extra Line 6 Tones).

Can someone please put a list with all cheats and the descriptions of what they do?

(if that matters, it is the PlayStation 3 version of the game)

Answer 1

The Guitar Hero wiki has an excellent summary of cheats in GH:WT. I'll summarize the cheats below, but I would recommend checking out their wiki for more details.

Available Choices

• Aaron Steele!, Jonny Viper!, Nick!, Rina! - unlocks the hidden characters.
• AT&T Park - Unlocks AT&T Park as a venue.
• Quickplay Songs - Unlocks all songs for Quickplay.

Appearance

• Air Instruments, Invisible Rocker - Hides instruments or band members, respectively. (You can't use both cheats at the same time.)
• Flame Color, Gem Color, Star Color, Vocal Fireball - Changes the color of the flames, notes and fret bar, notes in Star Power, and vocals' "comet", respectively.

Gameplay

• Always Slide - All notes, except for chords and open notes, can be played on the slider bar. (Guitar and bass only, of course.)
• Auto Kick - Kick notes will be played for you; you don't have to use the pedal.
• HyperSpeed - Unlocks HyperSpeed cheats for guitar, bass, and drums.
• Performance Mode - Hides everything but the stage; you'll have to play notes from memory.

Music Studio

• Extra Line 6 Tones - Extra guitar effects are available in the Music Studio. Line 6 does real-life amps and effects, and they licensed full amp and cab modeling for GH:WT, so unlocking this cheat makes those effects available to you.

Answer 2

The gem colors took me awhile to find out but it changes the color of the notes in the game...such as toxic waste, eggs and bacon and other cool ones.
