Hi guys, i'm looking for a 3 button footswitch with one stereo jack, one mono jack and 3 LED's. The first 2 buttons (stereo jack) should control the channel selection and boost for my amp (bogner shiva). The third button (mono jack) should act as an expression "pedal" for my Line 6 M13. Does this exist or am i looking at a custom build? Thanks in advance!
