When my Spider III amp was still with me, I sometimes play from 8pm to 11pm after work. Since I live in a building apartment, minsan may madidinig nalang ako sa taas na parang nagdadabog, like telling me to stop already, lol. Nobody confronted me face to face though. But being the nice considerate person that I am, I traded my amp and now practices through my pc using a good headphone para wala ng gulo. Ok na ko sa GT2 at sa G9.
