Beetronics Tuna Trem Tremolo/Vibrato

A Nine-Mode Tremolo Pedal in a Real Tuna Can

The Beetronics Tuna Trem is a nine-mode tremolo pedal that pairs an analog VCA signal path with digital control, packing classic waves, lo-fi textures, rhythmic patterns, volume swells and a killswitch into a hand-drilled tuna-can enclosure. It delivers smooth sine tremolo, choppy square pulses, broken lo-fi patterns, syncopated rhythms and blooming volume swells from a single stompbox, making it a fit for surf, experimental and performance-driven players.

Analog Signal Path With Digital Mode Control

The audio path stays 100% analog while digital control switches between the nine Species and unlocks features a pure analog circuit cannot deliver. Each mode saves its own depth setting automatically, so once you dial in your preferred intensity, that setting stays put. The enclosure is a real, hand-drilled tuna can — vegan, no fish involved — that gives the pedal its unmistakable look on a crowded board.

Nine Tremolo Modes Beyond Standard Sine and Square

The Species selector chooses between nine distinct amplitude behaviors, far beyond a typical two-mode tremolo.

• Surfer Bee: Sine wave — smooth, classic tremolo for surf and clean rhythm work
• Leafcutter Bee: Square wave — sharp, hard-chopping pulses for rhythmic stabs
• Sweller Bee: Volume swell — footswitch-held swells, Speed sets ramp-up, Depth sets ramp-down
• Morse Bee: Killswitch — momentary signal cuts, pedal stays always on

Multi-Function Footswitch With Per-Mode Memory

A single footswitch works in both latching and momentary fashion for sustained swells or quick chops.

• Speed: Primary knob — sets the rate of the selected mode
• Depth: Alternate control — hold footswitch while turning Speed to set depth, saved per Species
• Signal Path: Analog VCA — 100% analog audio with digital mode switching

Pedalboard-Friendly Power and Iconic Build

The Tuna Trem runs on standard 9V pedal power with a modest 50 mA draw; any standard pedal supply with the correct voltage and polarity will do.

• Power: 9V DC, center-negative, 50 mA
• Enclosure: Real hand-drilled tuna can — vegan, distinctive on any board
