Matthias Gill.

Hint: Foreign notes:
There are several foreign notes in a few songs. A foreign note is a note that is where it is not supposed to be. For example, a blue note in an easy song, or an orange note in a medium song. In the song "Raw Dog" under the easy difficulty setting, there will be a blue note in verse 1. Also, in the song "Arterial Black" under the medium difficulty setting, you will find an orange note in GTR Solo F. [Screenshot]

Hint: Select a song during the demo song:
When the game finally loads, allow it to idle at the title screen, with "Press Any Key". Wait for the song to load. Once it starts playing, immediately press all the fret buttons and flip the flipper. The screen will turn black, Keep hitting the frets and the flipper for several seconds, then stop. Occasionally, the "Song Failed Retry, Continue, Exit" message will appear. If you choose "Retry", it will start the song over. If you select "Choose Different Song", you may choose another song from the list. "Exit" just takes you back to the title screen.

Hint: Play with DualShock controller:
Use the following trick to play in multi-player mode with only have one SG controller. Playing with a normal controller is very different than playing with a SG controller. For example, you do not preset your fret and then strum; you just press the fret and it strums for you. It is easier than using a SG controller, but not as much fun. The button equivalents are as follows. Note: To navigate the menu, use Up and Down to go up and down. Press X to select the highlighted item and press Triangle to go to the previous menu.

Hint: Cheat with a DualShock controller:
If you are having problems entering the cheat codes with a PlayStation2 DualShock controller, you can use a DualShock controller from a PSOne. To do this, hold D-pad Left at the main menu, then convert and set the following buttons.
Zero Asakura.

Red: Circle
Blue: X
Yellow: Triangle
Orange: Square
Green: R2

Hint: Faster song list:
Go into the songs list for Career mode. Plug in two guitar controllers then make them both strum up or down (depending on where you are). It will make it go faster.
Kimberley Caldwell.

Hint: Hammering on and pulling off:
Hammering On and Pulling Off happens when you can strum on one note and successfully hit the notes that come after it without using the strum bar. Look for the single notes with white rings on top instead of black rings. As long as you hit the previous note, you can hit the next note by pressing the correct fret button. This is especially useful on songs like Cult of Personality under the Hard difficulty setting.
G. Rice.

Hint: Angus Young reference:
When you play a song with Clive Winston, occasionally he will move on one leg and move the other leg up and down. This is a move that Angus Young, the guitarist from AC/DC, did during concerts.
Mark2u.

Hint: Jimmy Page reference:
Play as Clive Whitnstin and activate Star Power. Sometimes he will pull out a bow and play the guitar with it. Jimmy Page of Led Zeppelin is famous for doing this.

Glitch: Get the Grim Ripper to play something other that the scythe:
You must have the Grim Ripper, and two files (medium and hard) to do this trick. In your second file, set the Grim Ripper as your character. Then, go into your first file and play as someone else. Give him or her a new guitar. Go back to your second file. The Grim Ripper should have another guitar other than the scythe.

Use the following trick to get Grim Ripper to play a guitar from the original Guitar Hero. You must have the Grim Ripper, and two files (medium and hard) to do this trick. In your second file, set the Grim Ripper as your character. Then, go into your first file and play as someone else. Give him or her one of the unlockable guitars. Go back to your second file. The Grim Ripper should have a Gibson Les Paul Cherry Sunburst Classic (which is not available for purchase in Guitar Hero 2.

Have the Grim Ripper selected as your career, then turn the PlayStation2 off and back on again. The Grim Ripper will cycle between all of your guitars.
Ryanwens.

Glitch: Use scythe guitar with any character:
Purchase the Grim Ripper, then load your file on Career mode. Select the Grim Ripper, then go back and select any character with more than one costume. Select the character, and they will be using the scythe.
Ben Dover.

Unlock the Grim Reaper. Go to Career mode and choose him. Then, go to change your character and choose anybody. It should say they are using the scythe. Play a live show and they will be using it.
Billy Henson.

Glitch: Reuse "Free Bird" scene on other songs:
First, complete "Free Bird" and have at least one more Encore song (a song you played for an encore) that is not "Free Bird". Use the Stonehedge level on Career mode. If you play an Encore song, it will use the Free Bird scenery, but play the song of your choice.

Glitch: Impossible to defeat Lou on Expert:
This glitch only works if you are battling Lou under the Expert difficulty setting. When you complete the first riff and you see the first long note, strum until you fail the song and Lou wins. Then, go to Tutorials and go to "Guitar Battle". When the God Of Rock finishes talking and you start playing notes, use the Battle Power and "Lesson 1 complete" will appear. Once that appears, pause the tutorial and go to "Quit". This will take you to Guitar Battle versus Lou. Battle him once again. When you are battling him, he will be on Easy while you are on Expert. To make Lou go back to Expert like he should be on, reset the game.
