i need to know what kind of guitar
No you don't need to buy a guitar.
For Guitar Hero on the Wii, all you really need is the guitar, a wii-mote, and the actual Guitar Hero game disk. The guitar strap SHOULD come with the guitar. That's all you need. :)
id say yes, just stay away from signature pickups because you need a lot more than just pickups to get say Slashes tone. Dimarzio X2N or Seymour Duncan Invaders for metal EMGs for modern hard rock or metal do some research or a lot of youtubing for that perfect sound you want.
chances are those "controls" pots....(potentiometer) need cleaning or replacing. Provided your guitar still does it on others amps, meaning there is not an amp issue, that should be #1, also assuming you have good chords and connectivity inside the guitar. Pot cleaner your self or find a guitar tech.
you need a guitar to play ALL guitar hero games.
If you want to teach yourself to play the guitar, the first thing you will need is a guitar and some picks. The second thing you will need is a book on how to play the guitar. and the third thing you will need is a way to tune the guitar, possibly a pitch pipe. Then you will need to tune your guitar. Then you open the book and start learning and practicing.
If you already have a guitar from Guitar hero you do not need to buy a different one. The game doesn't require a guitar controller but it does make things more fun with it.
no, you can use a controller.
NO. but u do need either a drum kit, guitar or microphone to play.
no you need the guitar grip
