GUITAR AMPLIFIER VA-10 Owner's Manual Thank you very much for purchasing a YAMAHA VA-10 Guitar Amplifier. The VA-10 is a two-speaker stereo guitar amplifier with built-in Distortion, Chorus and Delay effects. It can also be used to amplify acoustic guitar and electric basses. It's compact design allows easy portability yet produces a clean sound that is much bigger than its size. We hope you enjoy using the VA-10. To obtain maximum performance please read this owner's manual before using the amp, and then store it in a safe place. I CONTROL PANEL q w e r t !0 !1 I PRECAUTIONS N To avoid possible damage do not expose the unit to: • direct sunlight • very high or low temperature/humidity • sand or excessive dust * Especially inside a vehicle, the temperature may rise excessively - do not leave the VA-10 in your parked car on a sunny day! N Before connecting/disconnecting cables or turning the unit on/off, be sure to set the VOLUME control on the VA-10 to 0. N The VA-10 can be operated with six SUM-1 batteries or an optional AC adapter (YAMAHA PA-3). Use of a different AC adapter may damage the unit! When using a different AC adapter, make sure that its voltage and polarity (+ -) matches the VA-10. N Always turn the unit off after use. To avoid battery leakage, remove the batteries when the unit is not to be used for an extended period of time. N Neon and fluorescent lamps may induce noise. Keep the unit away from such lighting sources. N Handle the unit carefully - never apply excessive force to the controls and avoid dropping the unit. N Clean the exterior with a dry, soft cloth. Never use volatile liquids such as benzine or thinner. N After reading this owner's manual, keep it in a safe place for future reference.
