So I just got a Jackson Dinky 7 string guitar. At the store, I tried it out using the Spider IV Jam and I got amazing squealing pinch harmonics from it.
When I plugged the new guitar into my Spider IV at home, I can't get the same harmonics that I got at the store. All this time, I thought it was my technique but it was my amp. Is there something I can adjust on the amp to get the harmonics going? Thanks!
