or Interface, as well as the LEVEL on the CabClone IR section of your Badlander, BEFORE connecting the cable 

to the DIRECT OUT. This routine will help avoid unwanted (hot) signals accidentally sent during hook up from 

damaging your ears and those of others, monitor speakers, etc. 
GND/LIFT

A mini toggle Ground switch is provided, which can lift the circuit Ground from the chassis Ground. This “Ground 

float” switch can be helpful in eliminating some Ground loops caused by different references to Ground between 

Consoles, Interfaces, and the CabClone IR circuitry. 
Always start with the unit set to the GND (GROUND/upper) position when connecting the unit to a Console. 

If you experience noise in the form of hum or buzz, you can try the LIFT (lower) position to see if perhaps the 

noise you are experiencing is caused by a different Ground reference between the Console and the CabClone 

IR/amplifier. The switch does not always cure the noise problems associated with these differences in Ground, 

but it is often effective, and a welcomed feature when you’re anxious to get rolling in the Studio or do a timely 

Sound Check at a gig. 
CAB SELECT

These two 8-position rotary controls select the Cabinet IRs you will trigger in each of the Badlander Channels 

when connected to the DIRECT OUT and/or the HEADPHONE Output. 
Having separate rotary controls for each Channel allows you to set the Channels differently and optimize each 

Channel’s gain region, sound style, and response with a Cabinet best suited to what you’ve dialed up with the 

Mode Select, GAIN, Tone, and MASTER controls. This kind of flexibility puts the Badlander in a new category 

in terms of direct recording with a tube amp, enabling you to further authenticate your footswitchable sounds 

with a virtual Cab/IR that will not just broadcast them but rather showcase them. 
USB 

This standard USB port accepts a 2.0 A to B cable (not included) and is provided for connecting to a computer 

for managing the IR File directory. If you don’t have a 2.0 USB Cable around the house, it’s an easy Cart add 

at many online Retailers or available in most Music or Tech stores. 
The CabClone will appear on your Computer’s Desktop much like a USB Flash Drive and, once opened, will 

show you 3 separate folders labeled: Channel 1, Channel 2, and Cab Library. Each PRESET location on the 

8-position Cab Select Rotary has its own File within the two Channel 1 and Channel 2 folders, and they contain 

the same 8 “LIVE” IRs as loaded from the Factory.

NOTE: 

Important!! Don’t forget to eject the CabClone IR Drive from your computer’s Desktop just as you would 

a Flash Drive when you are done manipulating the IRs. 
HEADPHONES

A standard 1⁄4” stereo phono jack provides the Output for Headphones. This allows the Badlander to be not 

only a wonderful live performance and Recording ally but also a great tool and companion for “Silent” practic-

ing when you can’t make any “noise” for those around you. 
Like the Balanced XLR DI OUTPUT, the volume level at the HEADPHONES Output is determined by the LEVEL 

control. It’s not a problem that the two share the OUTPUT Control, as the DI OUTPUT’s feed is almost always 

sent to something with an Input Level control and EQ and the signal level at the 1⁄4” HEADPHONES Output has 

been attenuated/optimized for personal monitoring with headphones. 
That said, the impedance of the headphones (and their efficiency) can have an impact on the volume level pos-

sible, so it’s good to try before you buy if you have the chance, as efficiency can be as much of a consideration 

with headphones as their sound when choosing models or brands. The HEADPHONES Output will present a 

signal regardless of what other Outputs are in use.
