Tweek Mode : - note 1 - note 2   Note 1:   Tweek Mode gives you fine adjustment of Bass, Treble and Reverb for all sounds without having to edit.   Itís like having separate master Bass, Treble and Reverb knobs.   For example, you can . . .   a. Turn off reverb for recording.   b. Turn reverb down when gigging an empty hall. It happens!   c. Add a bit more top-end at a particular venue etc..etc.   To get into Tweek mode simply press EDIT/TWEEK.   The lamps above Bass, Treble and Reverb light to indicate Tweek Mode is now on.
