The GigRig Humdinger

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 with a high quality audio transformer. 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. 

Using the Humdinger to get rid of earth loops is easy. 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.

    Works perfectly

    I replaced a buffer in the middle of my pedalboard, with the Humdinger. Nopw i have a wet-dry setup, and a buffered output like before. And it works like a charm. No hassle whatsoever. Beautiful.

    Humdinger — Excellent

    Used to split signal into Blues Junior IV and Victory Sheriff 22. Zero loss of tone and allows for for a super simple wet/dry rig; with no phase issues.

    I got it to setup a dry/wet rig, works perfectly. The small size is great to fit under any board. Shipping came super fast all the way to Brazil. I'm super satisfied with it.

    Dings the Hum

    Very much enjoyed my first wet/dry rig experience thanks to the Humdinger. Really well built, great buffer and compact enough to fit on the underside of a mid-size Pedaltrain.

    I had a phase reversal issue on my wet/dry setup. The Humdinger made the problem go away with, literally, the press of a button.

    Great product. Really good musical sound from the buffer and the ground loop eliminator works well.

    If Dan is in the mood for a version 2, the addition of midi switching for the polarity inversion would be great. This would remove the issue of some pedals output being the reverse phase of the input when switched in and out of the signal chain. Not an issue in mono applications but certainly a problem in wet/dry or stereo rigs. For instance Victory V4 reverses phase on channel two compared to channel 1.

    Does what it says - no more hum in my wet dry rig (and squeezed onto pedal board)
