okay so i have a pretty decent guitar and amplifier but i want to get a multi effects pedal of some sort to get some nicer sounds, my question is, do you need two amplifiers to use the stereo function on the pedal? because i know that most effects aren;t as good without stereo but i didnt want to have to buy a whole new amp. Are there any alternatives, like plugging into speakers? or is my amp stereo> its a VOX VT30
