Hello, I'm wondering if anyone can help out a newb today. I picked up a second hand ampeg svt 4 pro for a steal of a price but after bringing it home and taking it to rehearsal I have no idea how to use it to max potential. I currently have it running through power amp a into a 800w ampeg PF cab at the practice room and the owner of the studio where we rehearse said I'm only using quarter of the amp but he doesn't know how to set them up. My old head was a ampeg PF 500 so it was super simple to plug in and play. For gigging I have a Hartke hydrive 4x10 1000w cab and a hartke 1x15 500w cab. Any advice would be amazing thank you.
