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.

    Using them for signal splitting feeding separate pedals loops for independent multi-track recording. Highly recommended.

    Bought this to use with G2 for splitting my signal to two amps and their effect loops. It just works! No noise, hum, phase etc. Perfect.

    Very small and easy to use. A must have if you are running more than one amp. I use mine in a loop on the G2 to send a signal to a dry amp (Wet/dry setup).
    There´s only one thing missng, it would be nice to be able to turn the buffer on/off.

    Great solution to this problem.....I was previously using a Lehle device, but the footprint of the Humdinger is much smaller and works just as well. No hum, no noise, just clear tone through both of my amps. I would highly recommend for anyone using two amps in a mono setup like mine - I am sure it would work equally well if you are sending one signal to your amp and need to send a duplicate to the PA!
