Ok so here's the deal I bought a nice Trace Elliot combo 2 weeks ago. It has 130 Watts and a 15" speaker. I dont play in a band (yet?). I have played keyboards in a band for 3 years though. Now when i practice at home, i have the volume set at 1/10, which seems like a reasonable volume to me. The master volume works with intervals, if i set it any lower i hear the bass itself louder than the amp. My parents (always seems to come down to this ) are complaining about the noise it is making. "the house is shaking", "i can hear it everywhere" bla bla. But the argument im most concerned about: u might be damaging your ears. I read this topic: http://www.talkbass.com/forum/showthread.php?s=&threadid=3743 My main questions are: -at what volume do you people play at home? do you use earplugs when practicing at home? -what is the consequence of this combo? i used to play with a 30W 10" combo. Is the difference in volume (i think it is equally loud, the TE just has more low end) or is it really in the low end? -when i set my combo to 1/10, playing 2 hours i nweekends on average and 1 hour on weekdays, can i do any ear damage? i cant really make sense out of this post: please gimme some more info on this! tnx!
