I like to play loud, and sinasabayan ko mga cds... so doble ung noise level. I live in an apartment, with one thin wall separating our apt. from the next door neighbor. When I used to use a 40-watt tube amp, the wall would shake. So, nagka-asaran na rin kami dahil sa ingay, and from friends, we've become permanent enemies.
I've made the concession of downsizing to smaller 15w tube amps, and am looking into the possibility of having a 1-5w tube amp head built, perhaps by Mang Raul.
And even though I only plug-in and play loudly on Saturdays and/or Sundays, I now make it point to stop playing by 9:00pm.
