# Amp Switch On

Used to turn on/activate a switch found on any tube/solid state amplifier. Amp switches are typically channel switching or effect switching like reverb, tremolo, etc.

You can control up to 4 separate amp switches by plugging each amp switch into any of the 4 UniPorts. Before you can control the amp's switch, you must assign the appropriate UniPort to be used for each amp. See [here](https://docs.jetpedals.com/books/unity6/page/global-settings) for instruction on programming each UniPort.

Select the UniPort number to control the amp's switch that is plugged into the corresponding UniPort
