I've never made my living from playing music, have always had a day job of some sort. Now, being in the Army full time puts a serious damper on playing in any kind of group, pro or otherwise (try playing in Baghdad, where I am now, for instance!).
I have, however, supplemented my income with gig money when I was able to play with a band. I do love playing in front of people. Unfortunately, back home, in Fayetteville, NC, I am in musical hell. It is a military town, and most folks want to hear basically three types of music:
country, blues (a lot of blues), and more modern stuff for the 20 to 30 year old crowd. I'm not knocking any of that stuff, mind you. It's just that none of it really does anything for me, so that when I am home, my vistas are very limited. I just can't see playing Travis Tritt tunes all night long, or a I-IV-V pattern, or worse, some modern rock song which requires that I play the whole tune on the E string. Again, not knocking it, just not for me.
I suspect that when my personal situation is more stable and reliable that I will find some group of folks to play with. Until then I'm pretty much a bedroom player, unfortunately.
The only reason I have Alembics now is that I have no children and hence, the disposable income that an Alembic requires. Same goes for my other instruments (I've got 19 in all, with another Alembic custom on the way). I'm not rich, just able to pick up the stuff I like.
Anyway, I'll always play in one way or another, I guess.
