This is not really an effect, but simply, as the name states, a line selector / switcher. However, it does have a “boost” capability and allows for some neat tricks, so it woudn’t be wise to dismiss it as a simple “switch”.
There are 3 controls: two are volume levels and the third is a “mode” knob, which has six postions. Two different color LEDs are used to indicate which output is active.
1st position “A<>B” alternates between A and B outputs (no bypass)
2nd position “A<>Bypass” selects between line A and bypass
3rd position “B<>Bypass” selects between line B and bypass
4th position “A>B>Bypass>” selects between line A, line B and bypass in sequence
5th position “A+B Mix>Bypass” selects between a mix of A and B outputs and bypass
6th position “Output Select” selects between Send A, Send B and direct output
One last note, this pedal has a DC out too: this means that it can be used with an external AC adapter and a cable to supply power to other pedals.
