Yes, that's right, "Guitar Hero: World Tour" have added two new instuments to the mix along with a newly designed guitar for you to rock out on.
The New Guitar:
Okay, here's the low-down on the newly designed guitar that will feature with the new Guitar Hero game. The new guitar has many more features then previous guitar models. One of the biggest and probably best feature on this new guitar is a touch pad on the neck next to the control buttons. This allows you to alter sustained notes by sliding your finger(s) up and down this touch sensitive stip. It can be useful if you wish to mimic a slap bass, which you probably will if you're a bass fan.
That's not the only design change that's been made. The back/select button has been adjusted and made to look like the bridge of the guitar, this makes it easier to find and easier to hit if you want to activate star power. This gives a more realistic look to the guitar design as well. The d-pad has been re-shaped to look more like a knob which gives it more style. Most (if not all) of the old features that have featured on previous guitar controllers will still be on this guitar so you're not going to miss all the oldies that much.
The Microphone:
The microphone is a fairly standard piece of equipment. It's wired, and it comes complete with buttons. Even with the buttons, you will still need to use a controller to get into the menus etc. To activate star power with-in the game you will not need to wait one of those special sections like you do in Rock Band, just tapping or making a quick sound will surely do the trick.
The Drums:
This is the one piece of equipment that I will definately enjoy playing with when I get this game as I'm a big drum fan. It has three pads, two raised cymbals and one bass pedal which makes it look more realistic than the drums in Rock Band. This makes up the basic set up of one snare, two tom-toms, two cymbals and a bass drum. The two cymbals are elevated above the three pads and you can adjust then to what-ever position you would due to the fact that they are on hinges. To activate star power with the drums, you just need to hit both cymbals at the same time and off you go.
For all you people that have just witnessed your next door neighbor's son or daughter walk in with a GH: WT pack, no need to worry. The drums are said to be a lot quieter than the ones included with Rock Band so it won't ruin your night watching endless romantic DVD's with your partners. Like the guitar, the drums are wireless which will make for less space consumption.
