JB-2 Angry Driver
Owner’s Manual

Before using this unit, carefully read the sections entitled: “USING THE UNIT SAFELY” and “IMPORTANT NOTES” (supplied on a separate sheet).
After reading, keep the document(s) where it will be available for immediate reference.

Main Features

The JB-2 is a distortion pedal cooperatively developed by JHS PEDALS and BOSS.

It is equipped with two completely independent distortion effects designed respectively by JHS PEDALS and BOSS.
By switching modes, you can use the JHS PEDALS and BOSS sounds individually, or use them together in series (with your choice of connection order) or parallel to create a wide variety of rock sounds.
If you connect a footswitch to the REMOTE jack, you can use it in conjunction with the pedal switch for additional options, such as switching between distortions or turning the effect on/off.

BOSS JB 2 Angry Driver - Overview

IMPORTANT NOTES

Some settings might cause the JB-2 to oscillate or might result in increased noise, but this is not a malfunction.
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.
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.
If operating this unit on batteries, please use alkaline or carbon battery.
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.
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).

Changing the Battery

Hold down the pedal and loosen the thumbscrew, then open the pedal upward.

The pedal can be opened without detaching the thumbscrew completely. 2. Remove the old battery from the battery housing, and remove the snap cord connected to it. 3. Connect the snap cord to the new battery, and place the battery inside the battery housing.
Be sure to carefully observe the battery’s polarity (+ versus -). 4. Slip the coil spring onto the spring base on the back of the pedal, and then close the pedal.
Carefully avoid getting the snap cord caught in the pedal, coil spring, and battery housing. 5. Finally, insert the thumbscrew into the guide bush hole and fasten it securely.
