Sorry, no canvas available

The Sescom Humbucket is an all-in-one hum eliminator built to eliminate hum in any and all of your applications! The Humbucket uses our famous Sescom hum-eliminating isolation transformer, as found in the classic line of IL-19 devices. These transformers are known for complete transparency through the entire audio band, while effectively isolating signals from the issues that can cause ground loop noise. The Humbucket also allows for connector and signal conversion from balanced to unbalanced and from unbalanced to balanced for your various applications. Hand-assembled in the US by Sescom engineers. Eliminate speaker hum, wire noise and more!
