A comment on picture #2:
I always thought that a guitarist who agreed to "turn his amp around" was just a myth..........wow!
They are a great band that are "emmm" getting old like the sound guy so we all share the same vision. Keep the volume down, let the pa do the work and go home happy at the end of the night. Most of the band now has switched to IEM or using a floor monitor for their mix independent including guitars so they don't even bring guitar amps. That night was a few years ago. Just out having fun now.
This was a for fun show and the last one we did due to covid. This was a private party last fall. Only the guest lead guitar player had a guitar amp which I thought didn't need much through the PA but sat at a good level in the mix. This was 2 - IG4T's and a single sub. Again for fun with no setup restrictions or requirements. ( code word for free ) . I thought even outside was sort of ok mix wise and as always the IG4T's do a good job with vocals. They to me just sound right.
