I don't have any gear except guitars, pedals and amps that I have built sorry.
No worries. I'm sure between us it would get sorted.
As I said, I can provide a PA with 12 channel desk, FOH/monitors; 4 vocal mics & stands and provide 2 guitar amps for backline.

Hopefully a bass player could provide 1 bass amp. If we have more than one drummer, I might be able to wrangle a kit somewhere.

The optimal scenario would be people just bring their guitars (and show off their builds!)
