This behavior depends on the effect settings in the WAZA Tube Amp Expander Editor.
By default, the EFFECTS button controls both the COMP and DELAY effects at the same time (when not using the editor). With the editor, you can change how the button works by setting each effect to ENABLE or DISABLE:
- ENABLE: The EFFECTS button can turn the effect on and off.
- DISABLE: The effect remains fixed, and the panel button has no control over it.
For example, if COMP is set to ON with DISABLE, and DELAY is set to ENABLE, the indicator stays lit because COMP is always active, while DELAY can still be switched on/off with the button.
