well as for the differents gadgets that are used on an electric guitar?! of course you'll need an amplifier. you can choose between clean or distortion by pressing a button on the amp.. and by just adjusting the knods you get different effects. eh.. probably a few pedals to help you when you're jamming to get the right effect without much trouble.
if u can afford an electric, it'll be so much better.. cuz there's so much more you can do on an electric.. one thing all my friends say, it's easier to play on electric.. like it's easier to fret, slide, bend and hammer.
