The strum bar of my GHWT (wii) guitar broke and saw that this guitar can also be used for the PS3 (which I'm getting in 2 weeks). I placed the order on Saturday and I received the package the following Tuesday, props to amazon uk for the fast delivery ( I live in Holland).
Putting it together was simple. A couple of instruction manuals were in the package, one quick guide, one for the wii and one for the ps3, and one for both consoles.
To make it work for Rock Band you have to push the lever on the receiver to the right. This was unfortunately not on the quick installation guide, but shown in the wii manual.
The strum bar and the fret buttons feel sturdier than the GHWT guitar I had. Although the power up button is not easily accessible while playing. You can of course raise the guitar for the power up but an easy to reach button would've been nicer.
The guitar works with Rock band 2 and Rock band Beatles for Wii, although I haven't tried it yet with the drumkit and the microphone.
