The Klowra Vein is the ultimate pitch shifter that fulfills every sonic demand you can imagine. Operating on an industry-lowest 8ms ultra-low latency polyphonic tracking algorithm, the Vein delivers the ultimate playing feel and near-zero hesitation. Even when facing algorithm-punishing pinch harmonics, it flawlessly preserves your instrument's original attack and dynamics. More importantly, it seamlessly integrates four core studio effects—Harmony, Pitch Shifter, Detune, and Glide/Ramp—into a single footprint.
To conquer the complex and unforgiving demands of modern playing environments, we purpose-built two completely independent pitch-tracking algorithms, engineered to precisely respond to your most extreme sonic requirements. Tight Mode perfectly preserves the organic "wood and air" of your original tone, completely eradicating muddy low-mids, purpose-built for razor-sharp, high-speed chugging; Classic Mode channels the legendary "Red Box" tone, specifically optimized for heavy bass grooves and synth-like sub-octaves.
Armed with independent Attack/Release controls and a dedicated Ramp function, a single footswitch allows you to freely navigate across a massive 17-interval, +/- 2 octave range. Whether it's major-second virtual hammer-ons, high-tension Whammy-style bends, devastating instant drop-tunes, or seamless dual-preset interval switching spanning 4 octaves, this versatile architecture completely eradicates the nightmare of hauling multiple guitars to a gig.
The Vein conceals a powerful Harmony system, unlocking up to 16 crushing interval permutations between your primary pitch and the harmony. Blended with the pure analog dry signal, it instantly constructs a massively oppressive, three-voice wall of sound. To further tear apart your spatial boundaries, the integrated LFO modulation coupled with the Detune function enables the microtonal true stereo engine to flawlessly simulate Automatic Double Tracking (ADT), injecting dimension-warping vibrato dynamics.
From subtle studio widening to chaotic, dimension-warping pitch destruction, the Klowra Vein doesn't just shift your tone. It redefines your sonic identity.
Details
Adjusts the LFO's pitch modulation frequency.
「Tone」Adjusts the high frequencies in the wet signal, allowing you to shape the tonal character of the effect.
Controls the mix between the dry and wet signals.
「RampRLS」Controls the release time of the Ramp modulation, determining how gradually the transition fades back to the Panel-Set.
Adjusts the attack time of the glide.
Adjusts the stereo deviation of the microtonal pitch.
「RampATK」Controls the attack time of the Ramp modulation, determining how quickly the fade reaches the Snap-Set.
PITCH SELECT:
Selects the interval of the pitch-shifted note.
-
Turn the knob to select positive intervals.
-
Press and hold the LED button while turning to select negative intervals.
Each selected pitch shift interval, or Root, automatically pairs with a specific secondary voice, or Harmony. The available intervals are:
-
Adjusts the release time of the glide.
-
Press and hold the LED button while turning the「GlideRLS」knob to control the volume of the secondary Harmony voice.
「Harmony」Controls the volume of the secondary voice relative to the main signal. Set to minimum to mute harmony, or increase to route it to the right channel—blending with your dry signal for a lush 3-voice stereo soundstage.
INDUSTRY-LEADING 8ms PITCH TRACKING LATENCY
Compressing tracking latency to a record-breaking 8 ms, Klowra Vein marks an unprecedented leap in polyphonic pitch algorithms. Build for players with the most unforgiving demands for tone and dynamics, it locks onto every signal nuance with surgical precision to completely eliminate digital artifacts. Even elusive pinch harmonics will never glitch or choke out, beautifully preserving every ounce of their screaming, metallic grit. Whether handling extreme down-tuned Djent riffs or massive slides, Vein eradicates low-end muddiness for an instant, lag-free response, keeping every texturized pick attack razor-sharp and immaculately defined.
REVOLUTIONARY BI-ALGORITHM PITCH ENGINE
To tackle today’s complex and demanding performance environments, Vein comes equipped with two independent pitch-tracking algorithms. This isn't just about pure precision—it’s about total respect for your string dynamics and native tone.
TIGHT MODE (Total Transparency)
Shift the pitch without altering your tone, it perfectly preserves the most organic "wood and air" of your raw sound. Optimized for heavy palm mutes, it ensures 100% restoration of your initial pick attack, clearing away low-mid muddiness to deliver razor-sharp, high-speed articulation.
CLASSIC MODE
(Deep-End Impact) Infused with the soul of the iconic "Red Box" tone. Optimized for massive bass requirements and synth-like sub-octaves, it delivers pristine, high-fidelity dynamic punch even in the absolute deepest registers.
17 INTERVALS WITH SEAMLESS TOGGLE
Klowra Vein packs 17 intervals spanning +/- 2 octaves, serving as the ultimate virtual capo that ends the nightmare of hauling multiple guitars to a gig. We’ve streamlined the interface for instant stage recall: simply hold the LED button to save your preset. From there, a long-press on the footswitch snaps instantly between your two locked-in pitches. Whether you need a massive drop for heavy breakdowns or a soaring upper-octave jump for synth-style leads, Vein executes every shift with zero-lag, glitch-free precision.
A WHAMMY BAR IN A BOX
Powered by Klowra’s ultra-fast 8ms polyphonic tracking, this is instant, real-time performance at your feet. We’ve meticulously tuned every transition to purge the jagged, cheap digital stepping found in lesser units. Whether blending seamlessly between dry and wet signals or violently sweeping from a high-octave dive into the sub-registers, the response is liquid-smooth. It’s not just a pitch shifter, it’s a true-to-life virtual whammy bar that delivers the organic, expressive dynamic range your playing demands.
HIDDEN HARMONY SYSTEM FOR A 3-PART WALL OF SOUND
Press and hold the LED button while turning the Glide RLS knob clockwise to awaken the hidden Harmony voice. This unlocks 16 crushing interval combinations between your primary pitch and the harmony. By blending this with the pedal's pristine 100% Analog Dry-Through signal, you can instantly construct a massive, three-voice sonic behemoth. Whether you’re stacking tracks in the studio or commanding the stage, it delivers an earth-shaking, immersive soundscape.
