Congratulations on your purchase of the YAMAHA AR-1500/AR-2500 Signature Guitar Amplifier. Please read this Owner's Manual carefully before using the product to ensure safe operation and optimal performance for many years.
The manual details safety precautions, such as connecting the guitar before plugging in the amplifier to prevent speaker damage, and setting the MASTER VOLUME control to minimum when powering on or off. It also explains how to use the various controls including Gain, Distortion, Master Volume, Sound Equalizer (Treble, Middle, Bass, Presence), and jacks for Effects Send/Return and Recording Output.
Make sure to plug in the guitar before plugging in the amplifier. Plugging in the amplifier first may cause damage to the speaker.
Be sure to turn the MASTER VOLUME control of the amplifier counterclockwise to its minimum position when plugging or unplugging the guitar cable and turning the power ON and OFF.
