I would bring at least one bass and two guitars, all vintage Japanese Grecos.
These are very high quality instruments. People can bring their own or play mine.
I have good cymbals and stands, kick pedals, etc. A complete 1970's vintage Ludwig Vistalite drum kit.
I have several amps available, these would be my first choice to use.
Small but sound fantastic. Would mic everything through the PA.
What you provide: PA system, stage monitors, microphones and stands.
This will be a high quality setup, once word gets out should be easy to book out.
This app is a game changer. The band can film their own shows and this automatically combines their video with high quality sound. Easy to set up, easy to use.
This added service provided to the bands will make them want to play at this venue.
