I have 4 mics and I believe there is both a SM57 and SM58 at the shop all with XLR connectors, and the 'New DI'(Thanks EBay) has 8 XLR Ports, so I think we will be good there.
I wish I knew where my 5th mic went
, It went MIA on me a while back(not HF related)
It wasn't expensive, but damn it, I did own one more.
I'm also debating if I should bring God Mode efx box, I had it last week to use as a Mic Preamp since the DI I used last week only had 2. However one of the mics I have is designed to be used with it, there's a little button on the side that can be used to turn effects on and off. So the mic user can control the effect.
