Sprout Modulation - Versatile Modulation for Creative Soundscapes!
The Klowra Sprout Modulation is a stereo multi-effect pedal packing nine studio-ready modulation effects — from classic chorus and phaser to flanger, retro rotary, ring modulator and tremolo. With tap tempo, the Ramp function and Analog Dry-Through, it gives you creative control while keeping a clean, uncolored tone. Ideal for guitarists and sound designers who want to modulate flexibly, experimentally and musically.
Sprout Modulation is a stereo modulation pedal with nine distinct effect types — ranging from classic, analog-inspired warmth and realistic physical modeling to creative, forward-looking sonic textures. Driven by high-quality algorithms and an open parameter architecture, it offers an extremely responsive and inspiring modulation platform for advanced sound design and exploratory sonic research.
Equipped with the exclusive Ramp function from the Bloom Infinity Series and tap tempo, Sprout Modulation enables dynamic, expressive real-time control. Combined with an expression pedal or an external footswitch, it opens versatile possibilities for nuanced, performance-oriented tone shaping.
Thanks to Analog Dry-Through, your dry signal remains entirely analog and uncolored while the effect signal is mixed in precisely. Selectable True or Buffered bypass and multiple stereo output modes ensure maximum signal integrity and flexible integration across live and studio setups.

Analog Dry Through
Analog Dry-Through mixes the effect signal (wet) with a fully analog dry signal path. Your original signal is never converted to digital while passing through the pedal and retains its natural dynamics, transparency and tonal character.

Tap Tempo
Tap tempo offers three rhythm modes and synchronizes the effect speed in real time with the song's BPM, so the modulation or delay locks precisely to the musical groove.

Two Bypass Mode
Via the power-up mode you can switch between Buffered Bypass (Trails On) and True Bypass (Trails Off). That way you decide whether effect tails remain after switching off or the signal is completely hard-bypassed.

Ramp Function
The Ramp function allows linear parameter changes and controls the smooth crossfade between two settings, creating dynamic, continuously evolving soundscapes with lively modulation.
