sure to set the VOLUME control on the VA-10 to 0.
◆ 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.
◆ 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.

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.

distorted during battery operation, the batteries are exhausted and
should be replaced with new ones (SUM-1 x 6). When the VA-10 is to
be used for longer periods at a time, we recommend the use of an
optional AC adapter (YAMAHA PA-3).
* Be sure to insert the batteries according to the polarity
markings (+ and –).
