SLINGSHOT REMOTE

The idea behind the Slingshot™ remote 
system was to cause something extra to 
happen simultaneously when making a setup 
change. For example, to switch from amp-A to 
amp-B with a single foot action, maybe change 
an effects processor. Another example could 
be switching from one channel to another on a 

vintage Twin Reverb®, and having the reverb go on or off automatically.  
Slingshot is basically a contact closure whereby when a connection is 
made using a standard ¼” guitar cable, a remote action can be triggered. 
With Slingshot™ equipped devices like the Headbone™ or Cabbone™, 
you can remotely toggle heads, cabinets or even move pedalboards 
around using the Twinline™. 

Connecting is as simple as plugging in a guitar. There are two selector 
switches that let you con

fi

 gure the circuit. The CONTACT lets you 

determine if the circuit is normally open or normally closed. This would 
for instance turn the remote device on or off depending on where it is 
set.  The CIRCUIT switch lets you set the Slingshot in a LATCH mode 
for old school amps or PULSE mode for newer amps.  Simply discuss 
the setup options with your dealer or the manufacturer to 

fi

 nd out what 

setting would work best with your intended setup. 

The Slingshot remote output may be activated using either the BOOST 
footswitch or the AB toggle footswitch. This is determined using a 
recessed set & forget switch adjacent to the boost footswitch.  When set 
in the outwards position to BOOST, depressing the BOOST footswitch 
will cause the Slingshot to trigger. When set inwards to TOGGLE, when 
you toggle between amps A and B, it will 

fi

 re.  Hitting the BOOST or the 

TOGGLE footswitch again will cause the Slingshot to return to normal 
or off.

Power booster 

Most guitarists use a 
combination of pedals including 
various distortion or overdrive 
pedals for rhythm and lead. As 
the Switchbone V2 will likely 
be the last pedal in the chain, 
the addition of a power booster 
enables the player to solo using 

any combination of pedals. A mid boost may also be engaged to add, 
sustain or fatten up the sound of a single coil pickup. Should the power 
booster not be required, the footswitch can be repurposed to mute the 
signal for quiet on-stage tuning via the separate tuner output. 

Output section

The Switchbone V2 may be used as a typical 
ABY switcher or con

fi

 gured to drive three 

amps simultaneously by re-purposing the 
tuner out to feed a third amp. In ABY mode, 
the center footswitch is used to select the 
active amp, while the left footswitch is used 
to turn them both on. Depressing a set & 
forget switch reassigns the BOTH footswitch 

to activate the Tuner/OUT-C. Outputs B and C are transformer isolated 
to eliminate hum and buzz caused by ground loops. 

Slingshot remote control 

Just imagine… being able to switch amps 
while activating a rackmount digital delay or 
in-amp spring reverb. Slingshot™ is a contact 
closure system that works with all kinds of 
devices to let you perform various tasks using 
a single foot-stomp. Add devices such as the 
Headbone™ head switcher or Cabbone™ 
cabinet switcher to change channels, heads 

or cabinets on the 

fl

 y. With the Twinline™, you can even share pedals 

between your two amp’s effects loops and have your pedalboard ‘move’ 
when you switch amps. The Switchbone V2 is designed to give you more 
control than ever before.
