Good thing my BL doesn't feel the same way about letting someone use his guitar. Two weeks ago Zac Brown sat in with us for 3 songs using the Bandleaders Gibson acoustic.It has nothing to do with being fantastic gear, I don't share my wife, my gear, my guns or my car. If you need food and clothes, no problem.
although not the same situation, it helped weed out the good from the hackers. I used the excuse- ''oh I forgot to switch out basses''
