The band I'm with has a limit of 2/3 gigs a month,
We pick and choose our gigs as we are a functions outfit with occasional pub gigs to trial new songs. Also other members have commitments outside of the band which keeps up the energy for gigs , rehearsals are booked well in advance and everyone has their homework to do before practice ,time is money after all,😀
It works out just fine for us
I'm 59 this year and started playing in my late teens, and the oldest in the band by a long chalk , it's still working out ok for me, I suppose it's about getting the balance right ,
Oh and lightweight gear is a must......looking for a barefaced as the TC electronic is a tad bulky 😋
