- For DC power: Connect a compatible 9V DC, center negative power adapter to the "DC IN" jack located on the rear of the pedal.
Connecting to Your Amplifier and Guitar
- Connect your guitar to the "INPUT" jack on the right side of the pedal using a standard 1/4-inch instrument cable.
- Connect the "OUTPUT" jack on the left side of the pedal to your amplifier's input using another standard 1/4-inch instrument cable.

Operation
Controls Overview
| Control | Function | Description |
|---|---|---|
| Mode | Selector Switch | Toggles between "Boost" and "Blues" modes. |
| Drive | Knob | Adjusts the amount of overdrive or gain in Blues mode. This control is bypassed in Boost mode. |
| Tone | Knob | Shapes the overall tonal character, from darker (counter-clockwise) to brighter (clockwise). |
| Volume | Knob | Controls the overall output level of the pedal. In Boost mode, this knob controls the clean boost level. |
| Footswitch | On/Off Switch | Engages or bypasses the effect. |
Using the Modes
The BB-2 offers two distinct operational modes, each providing a unique sonic characteristic:
Boost Mode
Select "Boost" using the Mode switch. This mode provides a clean volume boost without altering your core tone. It is ideal for pushing the front end of a valve amplifier into natural overdrive or for compensating for signal loss over long cable runs. The Volume knob controls the level of the clean boost. The Drive control is inactive in this mode.
Blues Mode
Select "Blues" using the Mode switch. This mode delivers a natural, warm overdrive. It is designed to emulate the tonal characteristics of classic Marshall non-master volume amplifiers from the 1960s. Use the Drive knob to adjust the amount of distortion, and the Tone knob to fine-tune the sound from dark to bright. The Volume knob controls the overall output level of the effect.
General Usage Tips
- Experiment with the Drive and Tone controls in Blues mode to find your desired sound, from subtle grit to rich, singing lead tones.
- Use the Volume control to balance the pedal's output with your amplifier's clean volume, ensuring a smooth transition when engaging the effect.
- The BB-2 is designed to interact well with tube amplifiers, enhancing their natural characteristics and responsiveness.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the pedal's exterior. Do not use abrasive cleaners, solvents, or excessive moisture, as these can damage the finish or internal components.
- Battery Replacement: If using battery power, replace the 9V battery when the effect indicator light dims or the sound quality degrades, indicating low power.
- Storage: Store the pedal in a cool, dry place away from direct sunlight and extreme temperatures when not in use for extended periods. Disconnect all cables and remove the battery if storing for a long time.
