Or in a room with everyone else tuning and such, lolol. I don't have to wait for those guitar players to finish their adjustments to get these close, close enough for me, and closer for others that want to fine tune, I would imagine. Just getting these resonant and sounding good, without fuss or bother, was a godsend for me.it is especially useful in a room/space where there is too much noise for tap and tune
or where you have to get a new head on in a short amount of time, and you need it to be evenly tensioned in under 10 minutes
At last nights gig, I just put the watch on each drum as it came out of it's case, very little tweaking, mounted them and was ready for sound check.
