Simply bypassing and engaging the MUX disables and enables its routing. This only allows you to switch between two sources. Note that bypassing the MUX will sum all inputs, which may have an impact on the signal level.

Multiplexer block (MUX)

Axe-Fx III, FM9: 2 blocks, 6 channels
FM3: 2 blocks, 4 channels

Axe-Fx II, FX8, AX8, VP4: n/a

About the Multiplexer block

The Multiplexer block, or MUX, is a routing and switching tool. It switches between multiple input sources. The input sources are rows on the grid (if you have them connected), physical inputs (Input blocks aren't required), or USB. Switching can be on-the-fly, through scenes or through channels.

Set each channel of the MUX to the desired input source. The MUX has 6 channels on the Axe-Fx and FM9, and 4 channels on the FM3.

A modifier can be attached to the Input Select switch, so you can use a switch or pedal to select the input. Only one input can be active at a time. This lets you connect instruments to multiple inputs and switch between them. For simultaneous inputs, use the Mixer block.

No gap is heard when switching sources, because the MUX crossfades very quickly between them. This provides an excellent way to switch between two Amp blocks on the Axe-Fx or FM9.

The Multiplexer block can't be bypassed and doesn't support Global blocks.

[1] If you want cross-fades between amps you would use two amps and the new Multiplexer block which cross-fades between input sources. You can set the input source to be any row or physical input.
