SANCTUM

Sonic textures no single reverb could ever reach.

Blend two sound spaces at once to build layers with unprecedented richness and depth. Create endless, ethereal atmospheres or keep the attack and articulation of every note with absolute stereo clarity. All the grandeur and dimension of a top-tier studio, right on your pedalboard.

Build spaces a single reverb cannot create.

One engine delivers the intimacy of a room; the other, the vastness of a reverb tail. Combine two algorithms with independent decays and tones to choose exactly how your mix behaves:

  • Parallel: Stereo separation and clarity. Keep a vocal or instrument upfront, with rich ambience behind it and no frequency clashes.
  • Series: Layered depth and density. Reverb A’s tail is reprocessed by Reverb B, creating cinematic ambience, washes and complex transitions.

Parallel: A and B both receive the dry signal and sum at the output. Ideal for a wide stereo image.

From an intimate room to infinite soundscapes.

Sanctum / Reverb

Divided

Splits the tail between left and right with alternating tremolo. The most stereo algorithm in the collection.

Two spaces at once. Textures no single reverb can deliver.

Instead of just stacking algorithms, Sanctum lets you fuse two independent acoustic spaces. Create combinations that were impossible before: an intimate, defined space for your attack, blended with a cosmic, expansive tail in the background — all in the same preset.

Everything in plain sight. Zero hidden menus.

Both engines appear side by side in real time. Change times, brightness and tuning instantly, without stopping the music and without reaching for a manual.

Instant access
Dedicated controls for what matters most: pre-delay, tone and wet/dry balance always at hand.
Intuitive tweaking
Switch between the two spaces with a single touch, keeping your full focus on your performance.
Individual control
Turn off one reverb without cutting the other, shaping live dynamics with complete fluidity.

The next sound begins before the last one ends.

When you change presets or bypass the effect, the previous reverb tail fades out naturally, with no abrupt cuts or dropouts in the dry signal. Seamless on stage, essential in the mix.

On preset change
The previous tone fades smoothly at the right time, with no silences or pops on stage.
Continuous transition (Trails)
Switch the pedal off and let the reverb evaporate into the air with no abrupt interruptions.
Analog signal preserved
Your original tone passes through 100% pure, with no volume drops during changes.

Maximum expression with the X and Y controls.

Every algorithm comes alive through two smart controls dedicated to the soul of the effect — from modulating the space or freezing an endless note to shaping the density of the shimmer. Decay and mix always stay in the same place, so you never get lost.

Dedicated parameters
Freeze chords into sustained pads or add tremolo and modulation without diving into menus.
Live switching
Toggle between series and parallel modes or recall your saved sounds straight from the footswitch.

Complete presets

Total tone memory. Save the entire acoustic scene: both reverbs, the signal order and every fine adjustment. Recall complex studio sounds with a single click on stage.

Independent EQ per engine

A perfect fit in the mix. Clean up muddy lows or tame harsh highs in each reverb tail, keeping your instrument clear and full.

Independent octave per engine

Harmonies and three-dimensional shimmer. Add octaves up for angelic textures or octaves down for cinematic weight, on each engine independently.

Stereo from end to end

Deep stereo immersion. Ultra-wide spaces that fill the whole room with no phase loss or cancellation, preserving the stereo image of your other pedals.

MIDI + USB-C

Full integration with your rig. Sync instant sound changes from a MIDI controller and use the desktop app to manage your sound banks with ease.

Trails on bypass

No more dry cuts. Play with the confidence of switching the pedal off at the end of a song and hearing the space fade away as smoothly as a real room.

Coming soon · Plugin

Sanctum inside your DAW too.

The same two engines, the same 13 algorithms and the same series or parallel routing, running as a plugin on your computer. Track with the pedal on stage and mix with the same reverb in the studio, preset by preset.

Uma das coisas de que mais gostei no Sanctum foi poder alternar entre dois reverbs dentro do mesmo preset. Ao vivo, consigo mudar rapidamente entre uma ambiência média e outra maior, sem ficar sapateando.

O Sanctum chamou muito a minha atenção desde o primeiro contato.

O Sanctum chamou muito a minha atenção desde o primeiro contato, tanto pelo visual quanto pelos primeiros áudios que ouvi. E, quando finalmente liguei o pedal, a experiência correspondeu às minhas expectativas — na verdade, foi além delas! Eu tenho um Strymon BlueSky e, sinceramente, depois de conhecer o Sanctum, não pretendo mais utilizá-lo. O Sanctum entrega aquilo que o BlueSky oferece e vai além, trazendo recursos que não encontramos facilmente em outros reverbs do mercado. Um dos grandes diferenciais é a possibilidade de utilizar dois motores de reverb simultaneamente, ampliando muito as possibilidades sonoras. Outro recurso que me conquistou, e que atualmente estou utilizando bastante, é a possibilidade de adicionar uma oitava ao reverb. Isso cria uma textura sonora extremamente interessante, diferenciada e cheia de personalidade. É um efeito que abre novas possibilidades criativas e permite explorar atmosferas que fogem do convencional. Na minha opinião, o Sanctum chegou para elevar o nível dos pedais de reverb e realmente provocar uma mudança nesse mercado!

Esse pedal é incrível

Esse pedal é incrível. É outra página que a gente tá vivendo no mercado nacional. Para quem toca worship e procura ambiências grandes, o Sanctum oferece possibilidades muito interessantes. Consegui montar um reverb espaçoso com uma oitava mais suave, pensando nesse tipo de som.

O Sanctum mostra que a VTR escuta a comunidade e desenvolve pensando em nós, guitarristas. É muito bom ver uma empresa brasileira fazendo equipamentos nesse nível e incorporando o que precisamos para tocar.
