I had an interesting time playing a “back line” set.  It was a high quality set – very complete – but with a few weak points. The main issues were the hi-hat, snare and bass pedal. Wait a minute ... aren't those the most important tools for a drummer? With a part missing from the hi-hat, a jammed snare release and a bass pedal badly in need of some grease, I had to be vigilant just to 'TCB' which, of course, takes away from playing music and my mental health.
