Cracked open the kit today, didnt get from play as they are sold out (grr) so no Bass guitar, but what I have got will review.
I have played rock band round a friends, and spent about an hour at the shops trying to choose between the 2, but thought I would go with GH.
First off, the drums, the reason why I bought the thing:
Annoying, the kick pedal is definatly better than RB, however the damn drums have the same annoying loud sound when you hit them, maybe a little less than RB, but thought they might of seen how many people complained about RB's that they would take it on board to look a better product.
Also The yellow symbol is terrible for picking up a hit, really bad when you have to hit it and another pad quickly, and also it can be easy to knock it from underneath it when hitting red, which messes up your score.
However the pads do have a good kick back on them, though I am starting to think I should of waited for RB2.
Pretty much the same as previous GH's, the neck is longer, which feels much better to hold, however the frets are very stiff and have to use quite a bit of pressure to get em down, also the strum bar has a very loud click to it, but on the plus side much better that it is stiff as not to hit a bum note as much as GH3.
I have not had a chance to use the new touch pad yet so cant comment on it.
The mic: Honestly, I don't think its ever going to be used until my mates are round and we are hammered, so no comment again!
I have to say the track list is poor, and the download content is a joke so far, however much more 'real' songs rather than the covers that RB had.
Its good, but I think RB2 is going to be a much better experiece for 1 player and multi player, I would wait for that, but in the meantime if you got the cash, then this is just about better than RB.
