Owner’s Manual AC DC AC & BATTERY POWERED FET
Thank you, and congratulations on your choice of BOSS AC-3 Acoustic Simulator. Before using this unit, carefully read the sections entitled: “USING THE UNIT SAFELY” and “IMPORTANT NOTES” (separate sheet). These sections provide important information concerning the proper operation of the unit. Additionally, in order to feel assured that you have gained a good grasp of every feature provided by your new unit, this manual should be read in its entirety.
Main Features ● Effects processor utilizes COSM technology to transform electric guitar input into beautiful acoustic guitar sounds. ● MODE knob allows you to select from a choice of four different acoustic guitar characters (tones). ● Features two types of output jacks, one for guitar amps and another for line out jacks, providing you with outputs suited to the connected device.
Panel Descriptions 1. AC Adaptor Jack fig.01 1 2 3 4 5 6 4 7 Accepts connection of an AC Adaptor (optionally available BOSS PSA-series). By using an AC Adaptor, you can play without being concerned about how much battery power you have left. * If there are batteries in the unit while an AC adaptor is being used, normal operation will continue should the line voltage be interrupted (power blackout or power cord disconnection). * Use only the specified AC adaptor (PSAseries). 2.
Panel Descriptions * If this indicator goes dim or no longer lights while an effect is ON, the battery is near exhaustion and should be replaced immediately. For instructions on changing the battery, refer to “Changing the Battery” (p. 16). * The CHECK indicator shows whether the effect is being applied or not. It does not indicate whether the power to the device is on or not. 3. LINE OUT Jack This output jack is used for connecting to mixers, recorders, and other devices that accept line-level input.
Panel Descriptions 6. Thumbscrew When this screw is loosened, the pedal will open, allowing you to change the battery. * For instructions on changing the battery, refer to “Changing the Battery” (p. 16). fig.02 8 9 10 11 12 7. INPUT Jack This jack accepts input signals (coming from a guitar, some other musical instrument, or another effects unit). * The INPUT jack doubles as power switch.
Panel Descriptions 10. BODY Knob 11. TOP Knob This adjusts the resonance of the sound produced by the guitar body, altering the characteristic mellowness and breadth of the acoustic guitar sound. This adjusts the sense of attack and the harmonic content of the upper range. 12. MODE Knob Provides for selection of the tone. The knob can be used to select any of four tones. STANDARD JUMBO ENHANCE PIEZO This tone is that of the popular Dreadnought acoustic guitar body style.
Connections * Raise the amp volume only after turning on the power to all connected devices. * The use of an AC adaptor is recommended as the unit’s power consumption is relatively high. Should you prefer to use batteries, please use the alkaline type. * To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections.
