The HumDinger is a compact signal splitter that runs one guitar into two amps at once, with a buffered main output and a second output that is phase reversible and uses our Hi-Def transformer-less isolation. It kills the earth-loop hum and phase cancellation that come with running two amps, and does the same job for DI, reamping and wet/d

Everything about this company and product has been top notch! Easy to order, daily email updates for shipping progress and the gear itself is the soul of simplicity to set up and use. It sits easily in your rig and is dead quiet, allowing all of your chosen tone to get through without 60 cycle or ground loop hum. I can’t recommend this company enough!!

Its ok, reduces hum and helps with phase and splitting. A bit pricey for what it is. Feels solid. If buying from the US, you may have issues. Mine sat in customs for a while, took 2 weeks to get it from date of order.
