It may be helpful to provide a list of vendors we have already contacted vs who we usually contact for events like this. I would be happy to help but I generally have no idea what I'm supposed to be doing,
Do large vendors (Sennheiser, AKG, Grado) usually show up or is it just the smaller local shops?
Is the focus usually on large-scale setups or portable rigs?
Do we only contact mfg's or shops as well (B&H/JR)?
