User Guide for VOX TREBLE BOOSTER Effect Pedal

Quick guide from the manual

The VOX TREBLE BOOSTER is a modern revival of the 1960s treble booster effect pedal. To ensure proper operation, note that the INPUT jack acts as the power switch when using battery power; always unplug your cable when not in use to prevent battery drain. The pedal requires a 9V battery or a 9V AC adapter (600mA or greater). When installing a battery, you must unscrew the bottom plate of the unit.

Product overview

This pedal is designed to bring out the appeal of the AC30 amplifier by boosting harmonics. It features an old-school circuit design with modern components to reduce noise while maintaining the authentic sound of the era. It includes a true bypass mode when the effect is switched off.

Part names and functions

• INPUT jack: Connect your guitar cable here. This jack also functions as the power switch when running on battery power.
• OUTPUT jack: Connect this to your guitar amplifier, other effect pedals, or devices.
• Effect switch: Toggles between the effect sound (indicator lit) and bypass sound (indicator unlit).
• FAT switch: Adds thickness to the low and midrange frequencies when switched to the right.
• Boost knob: Adjusts the amount of boost. Note that turning this knob may produce noise due to the original circuit design.
• DC 9V jack: Connect a 9V AC adapter (600mA or greater) here.

Setup

Battery Installation:

1. Unscrew the four screws on the left and right sides of the unit and remove the bottom plate.
2. Attach a 9V battery (6LF22/6LR61/6F22) to the battery clip, ensuring correct polarity.
3. Insert the battery and reattach the bottom plate.

Connections:

1. Turn off all connected equipment.
2. Set the Boost knob to the minimum level.
3. Connect your guitar to the INPUT jack.
