Overview

The Klowra Sprout delivers nine expressive modulation effects—all powered by the WildSeed Engine’s 24‑bit AD/DA conversion and 32-bit floating-point DSP—housed in a rugged aluminum chassis. From classic analog chorus and Uni-Vibe to advanced filter, ring mod, rotary, tremolo, flanger, and envelope-style filter, Sprout brings lush, inspiring modulation textures to any guitar or synth rig. Equipped with tap tempo, Ramp transitions, expression/footswitch control, and stereo flexibility, it’s ready for both studio and stage.

Key Features

• Nine Stereo Modulation Modes

  Vibe (Uni-Vibe), Chorus, Multi-Chorus, Flanger, Filter (synth-style VCF), Phaser, Rotary speaker, Tremolo, and Ring Modulator—all in one compact unit. 

• Tap Tempo with Subdivisions

  Sync modulation rate to your tempo using the footswitch, with quarter‑note, dotted‑eighth, or triplet subdivisions. 

• Ramp Function for Dynamic Expression

  Hold the footswitch to smoothly transition parameters (depth, rate) between knob settings—ideal for evolving textures. 

• Texture & Tone Knobs

  Adjust your modulation’s character—Texture softens or sharpens LFO feedback onset, and Tone sculpts brightness. 

• Analog Dry-Through & Selectable Bypass

  Maintains strong dry signal integrity via analog path, with user-selectable True or Buffered (with Trails) bypass. 

• Stereo Outputs & Routing Modes

  Offers both Dry/Wet separation and full true stereo imaging for immersive sound setups. 

• External Control Ready

  Use expression pedals or momentary footswitches with the TS/TRS input to control Rate, Ramp, or other parameters live. 

• USB-C Firmware Updates

  Update to firmware v1.1.0 (July 18, 2025) for enhanced rotary richness, stability, bug fixes, and Kill Dry improvements.

What Musicians Say

• Guitar Pedal X highlights Sprout’s strong choruses and phasers but notes the modulation palette as a “mixed bag” compared to Everlast and Limbo—but affirms it covers essential effects. 

• Tasty Jam Studios praises it as a serious powerhouse disguised in a pastel green enclosure:

  “Don’t let the pastel green enclosure and adorable plant logo fool you—this thing is a serious modulation powerhouse.”
