One Control Chamaeleo Tail Loop MkIII Switcher

The One Control Chamaeleo Tail Loop MkIII is a compact, lightweight 5-program loop switcher designed to streamline even the busiest pedalboards. With 4 series loops, 1 separate loop, built-in BJF buffer, mute with tuner out and power for up to 6 pedals, it gives you precise control over your signal chain while saving space and keeping your tone intact.

Whether you are juggling multiple gain stages, time-based effects and an amp effects loop, or you simply want consistent, repeatable sounds at the tap of a footswitch, the Chamaeleo Tail Loop MkIII makes complex setups easy to manage. Store up to 50 presets across 10 banks, switch between preset-based operation and direct control, and keep your core tone clear and natural thanks to the transparent buffer circuit.

On stage, the ability to recall entire combinations of pedals with a single press means tighter changes, fewer tap-dances and less room for error. In the studio, bank limiting and the lock function keep navigation simple so you can focus on playing, not menu diving. All of this comes in a low-profile chassis that fits neatly along the front edge of your board.

With flexible routing options, a dedicated mute and tuner out, and a carefully voiced buffer that can even be used on its own, the Chamaeleo Tail Loop MkIII is a powerful hub for guitarists and bassists who want professional switching without the bulk.

Flexible 5-Loop Routing

The Chamaeleo Tail Loop MkIII features 4 series loops plus 1 separate loop, giving you the freedom to place effects exactly where you want them in your signal path. Use the series loops for drives, modulation and ambience in sequence, and the separate loop for alternative routing such as an amp effects loop or a parallel path. This flexibility lets you build a cleaner, more organised board that behaves exactly how you need it to.

Preset and Direct Operation

With 50 program memories (10 banks of 5 presets), you can store detailed ON/OFF combinations for every song or section of your set. Program Mode lets you recall these instantly, while Direct Mode gives you immediate manual control of each loop when you want to work more spontaneously. Switching between modes is simple, so you can move from structured set lists to free-form experimentation without reconfiguring your board.

Transparent BJF Buffer and Mute/Tuner Out

The built-in BJF Buffer is designed for natural, transparent tone with gain set at 1, optimised input impedance and minimal noise. It preserves your sound across long cable runs and multiple pedals, and can even be used independently via dedicated BUFF IN and BUFF OUT jacks. The separate MUTE/TUNER OUT switch lets you silently tune or cut your signal between songs while still feeding your tuner a clean, stable signal.

Bank Limiting, Lock Function and Onboard Power

Bank limiting and the lock switch allow you to define a minimum and maximum bank range, making navigation faster and preventing accidental jumps to unused presets. This is ideal for live use where simplicity is key. On top of that, the Chamaeleo Tail Loop MkIII can power up to 6 pedals from its DC outputs (within the specified current limit), helping to reduce clutter and centralise your power distribution.

• 50 Programmable Presets - Store up to 50 different pedal combinations across 10 banks, so you can recall complete sounds with a single footswitch press instead of juggling multiple pedals at once.
• 4 Series Loops plus 1 Separate Loop - Arrange your pedals in four cascaded loops and one independent loop for advanced routing, making it easy to integrate amp effects loops, parallel paths or special-effect chains without rewiring your board.
• BJF Buffer and Mute/Tuner Out - Maintain clarity and dynamics with the natural-sounding BJF Buffer, and use the dedicated mute and tuner output for silent tuning and clean, professional stage changes.
• Bank Limiting, Lock Function and Master Bypass - Limit and lock bank ranges for quick, reliable navigation during gigs, and use Master Bypass to take the entire switcher out of the signal path when you want a direct connection.
