INSTRUCTIONS
POWERED
Please read these instructions carefully.
The BOSS TURBO Over
Drive OD-2 can give strong
distortion effect without
spoiling your delicate guitar
playing technique. The
TURBO ON/OFF Switch
allows you to select either of
the two types of the effects.
That is, usual delicate over¬
drive sound when TURBO is
OFF, and powerful overdrive
sound nearly as strong as
distortion when ON. The
TURBO ON mode also
allows a natural feedback
effect with little howling.

To prevent that, replace the battery, at
the time you might think too early.
