I can sympathize. The night I finally purchased my first Marshall stack, I bought a case of beer to celebrate. While I believe there is no better sound than a Gibson Les Paul plugged in to a dimed Marshall stack, my neighbors disagreed.
The cops paid me a polite visit at 1:30 am to tell me to turn it down. They paid another visit an hour and a half later to tell me the same thing (albeit a little more sternly).
I complied after the second visit.
