Main Features
- The BD-2 is the overdrive that has been specifically designed for crunch distortion.
- It can faithfully express the tone change caused by moving the knobs on the guitar.
- It can create distortion that can faithfully reproduce the picking nuance of the player.
- It can create wide varieties of distortions from crunch to hard distortion, by adjusting the Gain Knob.

- A natural-sounding overdrive continues to be produced without any loss in its quality, even if you turn down the volume on your guitar.

Precautions When Connecting
- To prevent malfunction and equipment failure, always turn down the volume, and turn off all the units before making any connections.
- Once everything is properly connected, be sure to follow the procedure below to turn on their power. If you turn on equipment in the wrong order, you risk causing malfunction or equipment failure.
- When powering up: Turn on the power to your guitar amp last.
- When powering down: Turn off the power to your guitar amp first.
- 5 Before turning the unit on/off, always be sure to turn the volume down. Even with the volume turned down, you might hear some sound when switching the unit on/off. However, this is normal and does not indicate a malfunction.
Use of Battery
- A battery was installed in the unit before it left the factory. The life of this battery may be limited, however, since its primary purpose was to enable testing.
- If you handle batteries improperly, you risk explosion and fluid leakage. Make sure that you carefully observe all of the items related to batteries that are listed in “USING THE UNIT SAFELY” and “IMPORTANT NOTES” (supplied on a separate sheet).
- When operating on battery power only, the unit’s indicator will become dim when battery power gets too low. Replace the battery as soon as possible.
