User Manual for VOX EFDSZJ 2 Fuzz Effect Pedal

Quick guide from the manual

The VOX EFDSZJ 2 Fuzz Effect Pedal is designed to recreate the classic 1960s fuzz sound. To get started, ensure you have a 9V battery or a compatible AC adapter. Connect your guitar to the INPUT jack and your amplifier or other effect pedals to the OUTPUT jack. Use the effect switch to toggle between the fuzz effect and the true bypass sound. Always turn off connected equipment before making or breaking connections to prevent damage.
