Thank you very much for your suggestion. well I've learned from what you've commented. well I am planning to buy Multi effects for my first try.. but well yeah I think you're right.
But I always play on bedroom. and I play Japanese Rock or any Instrumental songs. for example "G5 2007 "Words" " (sorry i can't post the link. It won't allow me, just check it on youtube if you have spare time) :)
