Jim: I don't (record myself, that is).
I have examples of my playing from various studio recordings I've made with bands over the years (LP's, audio-cassettes, and CD's).
A couple of years ago, a fan recorded me in my kitchen for a project on trad-jazz-improv (yet to be published). He had a smallish stereo-mic machine (I recall it was a digital recorder - maybe a Sony?) but the details are unknown to me. He transfered the audio to a CD for me. It turned out okay except for his commentary leading up to the start of a tune. I wish I could edit that out but alas, I don't know how.
I sympathize with your experiences with the results, though. On some recordings (mostly live, NOT in a studio), I wish my intonation was better (in tune with myself but NOT with the ensemble). I'm always conscious of that before a gig, trying to get in pitch with the piano, etc. When I hear some live recordings played back, I hit myself and wonder what in the heck I was thinking when I played THAT note!!!
