Brand new Morley Hum Eliminator (MHE) — 2-channel stereo ground-loop hum eliminator. Removes ground-loop hum and buzz between connected pieces of gear without changing your tone. Each channel has 1/4-inch and XLR inputs and outputs with custom isolation transformers. Great for pedalboards, studio rigs, and live setups. Brand new, never used.
