scratchy sound. This is normal.

a bit. Start at 7-‐10 for bedroom volumes.
TREBLE CONTROL:
This adds or subtracts treble. Start at 5 and adjust to taste.
MIDDLE CONTROL:
Adds or subtracts midrange. Start at 5 or 6, lower settings will scoop the mids, higher levels
will allow your audience to actually hear the guitar in the mix.

to hear this Runt bark.

FOOT-‐SWITCH JACK:

SEND JACK:

AXIS SWITCH:
Simulates MIC placement on the center of the speaker or the edge/surround.

A level pad for the XLR output.
SPEAKER OUT JACKS (2):
Plug your speaker cabs in here. If using only one cabinet, connect to “USE FIRST” jack.
The Runt-‐20 has a built in dummy load in case you want to use the XLR output without having a speaker
connected.
IMPEDANCE SELECTOR SWITCH:
Set to correct speaker load impedance that is connected to your amp.
HT FUSE:
Only replace with designated fuse value, appropriate to the voltage in your country. If this blows, don’t
freak out too much. It’s most likely a bad power tube. We recommend you carry a few spare fuses and a spare
set of tubes when gigging. If the fuse continues to blow after swapping out the tubes email us for support at
[email protected] and we’ll help you sort it out…
MAINS FUSE:
Replace with 2 amp Slo-‐Blo (North American Voltage – 117V) or 1 amp Slo-‐Blo (Euro Voltage-‐230V).
This is located in the IEC Housing.
MAINS INPUT:
Plug the supplied IEC power cord here (make sure the mains voltage is correct).
