The MOOER Thunderball is a compact bass distortion and fuzz pedal designed to deliver everything from mild grit to aggressive, thick, vintage-style fuzz. It is specifically voiced for bass, aiming to add drive and attitude without completely losing the fundamental low-end weight of your instrument.

Sound and character

• Aggressive bass fuzz: Creates a thick, hairy, saturated tone with a raw, vintage character.
• Classic distortion: Produces a tighter, more defined overdriven sound that retains more of your original bass signal.
• Strong low-end presence: Adds grit without making your bass sound thin or disappearing beneath distorted guitars.
• Adjustable gain: Moves from a subtle dirty edge to heavy, snarling saturation.
• Compact design: Packs two distinct drive styles into a small pedalboard-friendly enclosure.
