The AX2 defaults to an ‘immediate’ editing mode in which the sound will instantly reflect the knob settings (i.e. when you change a knob, the sound changes immediately). You’re used to the older ‘capture’ mode editing of the AxSys 212, where you had to move a knob to the position of its stored setting before you could change the setting. You can put the AX2 into the older editing mode by holding down the Main Row Edit Select button while powering up the amp. This setting is stored with the other Global settings, and you’ll never have to think about it again unless you do a reset of the amp. (See page 2•2 of the manual)
