UnderLiner also features an active loop enabling you to integrate effects in your amps’ effects loop with no tone loss from long cable runs. 

Switch between your settings with the included UnderLiner FS Footswitch which will also provide power to the UnderLiner sitting back at your amp. 

​UnderLiner is also remote switch and MIDI enabled so you can program the UnderLiner as part of your presets with G3/G2/Atom or any other programmable remote switch or MIDI controller.
