second, this is just my preference. i like to jam along with song blast on pc speaker. so i prefer to have a guitar amp instead. sometimes i connect my amp to laptop (watch movie n such bcause its loud lol), so i just play the song and play guitar on the amp(though the guitar sound wont sound nice when run along with mp3/laptop).... using amplug with head phone, i dont think cant really listen to the song. i dont know whether its possible to connect mp3 player or pc into amplug.
judging by the series they offer... I already know an amp for a certain sound... just hoping for actual usage comments though >.<
I guess I'll have to try it out myself (if I can)
