A New Kind of Echo Experience
The Himmelstrutz GEKKO is not your typical echo pedal. It is neither dark and murky nor bright and sterile. Instead, GEKKO creates space and dimension around your sound, adding depth, movement and character without getting in the way.
Unlike many modern delay pedals that focus on strict tempo matching and pristine repeats, GEKKO thrives on organic movement and musical unpredictability. Set unusual tempos, create layered textures and discover echoes that feel alive rather than programmed.
Inspired by Classic Echo Machines
GEKKO takes inspiration from legendary echo units such as the Echorec and Binson, carrying their musical spirit into a modern design. It is not a recreation of vintage gear but a reinterpretation that adds dimension, air and depth to your sound.
Each repeat is carefully voiced to support the original signal rather than overpower it. The result is a spacious, organic echo that enhances your playing while remaining responsive and musical.
No Restrictions on Your Creative Tempo
GEKKO allows you to explore unusual and offbeat delay times without losing musical coherence. While many delay units require strict BPM matching, GEKKO remains natural and integrated even when set to unexpected tempos.
This freedom encourages experimentation and opens the door to unique soundscapes, textures and rhythmic possibilities.

Handmade in Sweden
Like all Himmelstrutz creations, GEKKO is handmade in Sweden. Every unit is built with a focus on reliability, craftsmanship and unique sonic character rather than mass production.
The result is a distinctive echo pedal that comfortably stands alongside both vintage classics and modern designs.
Engineered for Dimension and Air
GEKKO is designed to add depth, movement and atmosphere to your sound. Rather than producing sterile and repetitive echoes, it introduces subtle variations that keep your tone alive, dynamic and engaging.
It creates space around your notes, adding an extra dimension without masking the original signal.
More Than an Echo
GEKKO is not only an echo effect. With the MIX control turned down and the VOLUME control turned up, it becomes an excellent boost pedal.
It can also create ambience similar to a reverb effect. Because GEKKO is not overly sensitive to exact tempo matching, it can often be set freely while remaining musical and easy to play with.
Looking specifically for classic spring reverb territory? Consider the Himmelstrutz Sprnklr or SPRNKLR Plus.
Conclusion
If modern delays feel too polite, pristine or predictable, GEKKO offers a refreshing alternative. It delivers echoes with personality, movement and dimension while remaining highly musical.
And if you simply want an exceptional sounding boost, turn down the MIX, turn up the VOLUME and enjoy the ride.
