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.

    Rugged and small enough to fit under most slanted boards, I have a T-Rex tone trunk (the one which is 56 cm wide). Easy to use, just plug in your amps and use your ears select a phase setting.

    Wow!! As an avid follower of That Pedal Show I was intrigued by this device that allows you to play through two amps at the same time without any phase issues. I have a Marshall TSL 601 and a Fender Hot Rod Deluxe. For some time now the Marshall had languished at home as the music my band plays has veared more towards the punky poppy side of things but I have always loved that Marshall tone. Now I am able to blend both amplifiers and wow what a sound! Using both amps clean, not just reverb delay and modulation come alive but my drive pedals sound fuller and tonally more dynamic especially my OCD and tube screamer mini in combination. As well as the obligatory D&M Drive. Well done GigRig for another fantastic piece of kit. One day the G2 will be mine.....oh will be mine! For now though my rig with the humdinger is amazing and I can’t wait to get out and gig it again soon!

    Perfect. Allows me to output from my pedal chain into a vintage Nomad Axxeman preamp (solid state from the eighties) and a Mesa Boogie Quad preamp (tube of course) from the nineties. From these 2, they go into dual stereo inputs on my interface and then 2 stereo tracks on my DAW. This means that I can simultaneously record individual tracks from each of the preamps and either decide which I like the best, or keep them both blended together. The Humdinger prevents earth loops and keeps it all quiet. It's flippin' heavy which shows the quality of it. Typical Dan!!

    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.
