Operation
Using Guitar Amp Channel Switching
(Amp Control)
By connecting your guitar amp’s channel switching jack to the OD-20’s AMP CTRL
jack, you can then use the AMP CTRL button to switch the amp channel.
This combining of the OD-20 and the amp channels allows you to get an even
wider variety of distortion sounds.

* To determine how the amp channels are switched when the circuit is open and shorted, refer
to the amp owner’s manual, or actually confirm the sounds by operating the amp.
* You can set the Amp Control independently of the effect On/Off settings.
* You can store separate Amp Control settings to each memory. For more on this procedure,
refer to “Storing Settings (Write Operation)” (p. 10).
With Amp Control, not only can you switch amp channels, you can also
use it to switch the amp’s effects on and off, like a foot switch
controller.
