Footswitch-enabled guitar amps

For footswitch

— the presence in the combo amplifier connector for the pedal (footswitch).

The pedal is the most convenient way to quickly change amp settings and can be used while playing the guitar. The specific functions "tied" to the pedal connectors can be different: in particular, various effects can be turned on and off in this way. Also, in different models, the number of connectors for pedals may vary: in most “amps” there is only one such connector, however, there are models that allow connection of several “foot switches” at once.
