Split your signal, correct phase & kill hum.

Great for DI, reamping, wet/dry and plenty more besides.

The Humdinger was designed to eliminate earth loops in audio equipment by isolating the second output. Earth loops are a common complaint. As soon as the ground on your gear has more than one main route to earth, you have the potential for an earth loop. The best and safest way to get rid of an earth loop is to isolate the ground that is causing the hum. 

If you use 2 amps all you need to do is stick the HumDinger at the end of your effects chain. Your main (buffered) output goes to one amp and the isolated output goes to the other. Your earth is consistent through the main output but isolated through the isolated output. 

Using a mains powered effects pedal, simply place the HumDinger in the chain after the mains powered effect. The Mains powered effect is your main ground and the ground from the amp is isolated.

    Brilliant device. Smaller than it looks in the photo’s so doesn’t take a lot of space on the board but the ability to run wet / dry quietly and safely is brilliant. If you have two amps and haven’t tried wet / dry, but one of these and enjoy clean pure tone.

    Humdinger Review

    Posted by Chris on 6th Feb 2021

    Great product, has enabled me to run my two amps wet/dry properly for the first time, and now I'm well down that rabbit-hole! Huge sound, even at low(ish) volume, and no extra noise, thanks to the Humdinger.

    As soon as you get it in your hands you know the Humdinger is a quality product. Beautifully built and works like a dream. So quiet in use and perfect for a wet/dry setup. Comes nicely packaged too.
