Make sure the AcoustiFX is hooked up properly and turned on, as outlined in chapter 3. Change programs in one of these two ways: Foot pedals This is the easiest way to switch programs, especially while playing your guitar. Just step on the left foot pedal to decrement the program number and the right to increment it. You can hold down a pedal to increment or decrement programs continuously. Play your guitar to hear how the program affects the sound. 1 2. 3 2 3. 3 20 6 Editing Programs To Edit a Selected Program 1. Turn the EFFECT knob to the effect module or parameter you wish to modify. As soon as you change the value, the EDITED decimal point on the display lights up to show you a change has been made to the current program. If the module has a parameter (PARAM), turn the EFFECT knob to select the parameter. Continue in this way until you have completed assignments for all modules and parameters.

Just turn the EFFECT knob to exit the RESTORE FACTORY PRESETS mode, or turn the unit off and then on again. 21 7 Using the Tuner To Tune Your Guitar 1. In PLAY mode, enter BYPASS by pressing both foot mode pedals at the same time once, or enter MUTE mode by holding them both down for more than half a second. Make sure your guitar is connected to the AcoustiFX, and play the open string you wish to tune. The left digit of the display indicates the pitch nearest that of the open string. Look at the right digit of the display to determine if the pitch is correct. If the top four segments of the digit are rotating clockwise, then your guitar's pitch is higher than the pitch shown in the first digit. If the bottom four segments are rotating counterclockwise, the pitch is low. Tune the string until an 8 appears in the second digit, indicating that the string is in tune with the pitch displayed in the left digit. [. . . ] Batteries low. No sound, level low.
