The Rolls HE 18 is a surprisingly effective little box for tackling ground loop hum – that annoying buzz that plagues so many live and studio rigs. It’s a budget-friendly solution that’s perfect for anyone dealing with hum issues, especially those with older equipment or complex setups involving multiple devices. It’s not a miracle worker, but it’s a solid, reliable tool for cleaner audio.
