You can store Local Presets of any individual component of the signal chain (Input, Stomp ABCD, Amp, EQ, Cab, X, MOD, DELAY, REVERB)* as well as on group level (STOMPS, STACK, EFFECTS).
If you for example have STACK in focus and push the STORE button, you can chose either to store the complete rig or capture a preset of the stack.
In order to leverage such presets in any other rig, You just need to put the corresponding component or group into focus. Now you can browse through your presets stored before and load one of those.
This is a very effective method to capture and leverage your favorite building blocks.
*Presets of the MASTER settings are not yet available.
