In this case, decrease the guitar's volume, or adjust the AG-Stomp's VOLUME, individual Tone Controls or individual Effect knobs. Also, if feedback occurs, please use the Feedback Reduction Function described on page 16. 15 Using the AG-Stomp G Feedback Reduction The AG-Stomp is equipped with a Feedback Reduction Function to prevent feedback. Feedback is caused when a certain frequency or frequencies of the amplified sound causes the guitar to resonate thereby being re-amplified until a steady howl or whistle is heard. The AG-Stomp prevents feedback from occurring by means of a notch filter, which is used to cut the problem frequency. The AG-Stomp provides a total of five notch filters (1-5) that can be applied and operate simultaneously. The AG-Stomp will automatically identify the problem frequency and apply an available notch filter. * The DEPTH is set to its maximum value (knob 10: -20dB) in the AUTO setting. * When feedback occurs with chords, etc. , the AUTO setting might not provide adequate performance. In this case, use the MANUAL setting as described in the next section. After adjustments have been made, press the same button to set the setting (the lamp will light and the filter will be active). To deactivate (lamp OFF) an active filter (lamp ON), press and hold the button of the filter you want to deactivate until "OFF" appears in the display. * Refer to the "EFFECT FUNCTIONS and PARAMETERS" section (page 21) for more information on settings for each of the Feedback Reduction's knobs. If feedback is continuously occurring at a high volume level, it may cause damage to equipment. Please use caution. · MANUAL Setting Press one of the [FEEDBACK REDUCTION] buttons 1-5 (its lamp will flash). Use the FREQ knob to select the frequency that needs to be cut, then use the DEPTH knob to adjust the amount of reduction needed. Depending upon Utility Mode settings, Feedback Reduction settings are either included with patch data (PrG) or, kept separate of patch data so that the same Feedback Reduction settings/parameters will remain active (GLb) even though a different patch is selected. ( page 27) Also, if the "GLb" (global) setting is used in the Utility Mode, Feedback Reduction settings will be stored as global data when patch data is stored so, the settings will be erased if the power is turned off before the settings are stored. Signal Level Amount of reduction Frequency that needs to be cut When another patch is selected, any settings that were changed will be returned to their original condition. If you want to keep the changes you made to those settings, use the Store Operation described on page 19.
