HUMDINGER
THEGIGRIG HUMDINGER USER MANUAL
TheGigRig HUMDINGER
is an active splitter with a buffered output (Out 1), and a buffered, isolated, phase reversible output
(Out 2).
HUMDINGER
INPUT: Plug in here
POWER: Uses a standard 9V DC 2.1mm centre negative
power supply @100mA
OUT 1: This is the normal straight through output and
includes the ground/earth
OUT 2 ISOLATED: This is the output that gives the option
of isolation and reversing the relative phase to output 1
OUT 2 PHASE: Flips the phase on output 2
EARTH LIFT: Enables you to lift the earth on output 2
In Operation
Connect a standard 9v DC centre negative 2.1mm plug
power supply that can deliver at least 150mA.
Connect your guitar/bass signal to the INPUT. Connect
outputs 1&2 to wherever you need them to go (see example
diagrams).
PLEASE NOTE – Output 1 is your main earth/ground
connection so ensure this is always connected.
PHASE:
Out 2 features a phase switch. This will reverse the phase on Out 2 relative to the phase on Out 1. With both amps on, toggle the
phase switch to see which position has more bottom end and volume. The position that has more bottom end will mean both
amplifiers are in phase.
EARTH LIFT:
Out 2 features an earth lift switch. With this button pushed in, your signal earth is connected through Out 2. With this button
disengaged (button out), your earth/ground is lifted. This results in isolation between Out 1 and Out 2 and will remove any earth loop
noise you get from connecting two amplifiers together.
PLEASE NOTE: Out 2 is an exact mirrored image of Out 1. The phase switch works regardless of the configuration of the earth lift
button.
Set Up Examples
END OF CHAIN SPLITTING:
The most common way to set up the HumDinger is to position it at the very end of your signal chain, enabling you to split your signal
between 2 different amps. You can also send your Out 1 to your amp and the isolated output to your DAW for re-amping later.

TPS WET/DRY:
The Humdinger’s separate outputs can be used to split the signal path. An example of this is a TPS WET/DRY. In the diagram below
the signal is split after the gain stages; the Out 2 ISOLATED output is sent to your dry amp and the Out 1 BUFFERED output is sent to
your wet effects (delay, reverb, etc.) then to your wet effects amp. It’s a great way to get faux stereo sounds from what is essentially a
dual mono signal path. From here, a Wet/Dry/Wet set up is as easy as connecting the wet side in stereo and having the dry amp in the
centre.
