Can you consider it a double if you don't own (have in your possession) the instrument? How well must you play before the instrument can be considered a double? I don't like playing borrowed instruments so I generally decline jobs calling for an instrument I am proficient on, but do not own. I often encounter the folks who have accepted these gigs at the performances and most of the time, they have borrowed instruments and are not giving a strong performance. It's a bit of a dilemma for me. On the one hand I am a much better musician, but borrowed instruments aren't likely to be in very good condition and so I wouldn't want the poor quality instrument to make it appear as though I do not know how to play it - as the player in question appears. On the other side are the hobbyists with deep pockets and a huge arsenal of high quality instruments, which they can barely assemble, let alone play. Some days I feel like I fall into this camp, except for the having money to buy instruments on a whim. Nothing seems to work and I wonder why I am not home with the family or walking the dog. What are your thoughts? Am I alone here? .
