I have a terrible sleep schedule, usually waking at 2am and going back to sleep at 5am.
Most often, I play the Martin; none of my amps has a headphone jack. But 3am is when I'm ready to rock. Sometimes, I just want to plug in the Tele, crank up the amp, and write and play. Imagine--I live in a quiet and "respectable" suburb. Occasionally, my older neighbor will say, "Heard you playing yesterday. Sounded good." I never play above 3 on the Deluxe, even during the day. Neighbor said it wasn't loud.
There are a lot of musicians in this town. If I had the dough, I'd open a rehearsal space for bands and solo players. It'd be a great place for musicians to meet. It would be an attractive thing for those like me who are "acquainted with the night" (Robert Frost).
