Modular Multi-Effect Processor
28 studio-quality effects, now with a complete Amp & Drive rig — classic pedals, five modeled tube amps, a physical-model cabinet, and a hybrid amp designer — plus a themed grouped layout for every module. Route, stack, and shape your sound with complete creative freedom.
Building a multi-effect chain across the 4 slots
- Load a preset — it drops into Slot 1. Click the lock icon (the slot border turns orange), then load another preset and it fills Slot 2. Repeat to stack up to 4 effects.
- Load into one slot — click a slot's box in the flow strip to select it (it gets a purple border); the next preset you browse or step to loads into that slot only.
- Random Mix (the shuffle / crossed-arrows button) randomizes every unlocked slot at once — so lock the parts you like and keep shuffling the rest.
- Drag the dashed strip under the effect animation to reorder slots, or right-click it to copy/paste an effect into another slot.
What's New
A complete Amp & Drive rig — classic Distortion pedals, five modeled tube Amps, a physical-model Cabinet, and the hybrid Amp Lab — plus themed grouped layouts, a rack overview visualizer, and 105 new factory presets.
Distortion — Three Classic Pedals
Three pedals modeled from the circuits up — Scream (smooth mid-forward overdrive), Rodent (gritty hard-clipping distortion), and Violet (huge sustaining fuzz). Each has its own gain character, tone shaping, and look, with an audio-reactive circuit-window visualizer that responds to your playing. Drop one in front of the new Amp for a proper drive-into-tubes rig. Pro.
Amp — Five Tube Amp Families
A tube amplifier sim with five modeled families — Brit 800, Black Duo, Chime 30, Chime S1, and Solo 100 — each with a living power-tube scene and its own chassis theming. Models load instantly, and a three-tier Quality knob (High / Balanced / Eco) trades CPU for fidelity without losing the voice. Pro.
Cabinet — Physical-Model Cab Sim
A speaker cabinet simulator with no impulse responses — the box, speaker, and mics are modeled physically. Position two independent mics on an interactive pad, blend condenser, dynamic, and ribbon types, choose from a roster of modeled speakers and cab sizes (1x12 to 8x10), and add a room layer for air. Pro.
Amp Lab — Hybrid Amp Designer
Build the amp that doesn't exist: pair any preamp with any power section across the five families, then shape the result with nine character knobs. A seam-flow visualizer shows the signal handing off between the halves. Load one of the new multi-slot Rigs presets to hear full pedal-amp-cab chains in one click. Pro.
Why Spectrus?
4-Slot Modular Architecture
Chain up to 4 effects in series or parallel. Each slot has independent level control and wet/dry mixing for precise sound design.
Flexible Signal Routing
Route any slot to receive from the main input or any previous slot. Create complex effect chains with ease.
28 Studio Effects
From classic modulation to lush reverbs, tape delays to spectral processing, a Texture category for granular and glitch sound design, and the new Amp & Drive category — pedals, tube amps, cabinets, and the hybrid Amp Lab.
Dark & Light Themes
Switch between a polished dark theme and a bright light theme to match your DAW or your mood. Every control, meter, and visualizer adapts instantly.
Per-Slot Tone & Stereo
Dedicated Air (sparkle) and Body (warmth) knobs on every slot, plus a new Stereo In control on every effect that continuously blends between classic mono-sum processing and full stereo. No more choosing between vintage character and width.
1056 Factory presets
Save and recall your favorite configurations. Organize presets into folders. Lock slots to preserve settings across preset changes.
Low CPU Usage
Optimized DSP code means you can run multiple instances without bogging down your session.
Try 23 Effects Free
Demo mode gives you full access to 23 effects — including all 16 established Pro effects — so you can explore before you buy. A gentle periodic fade is the only reminder.
Slot Lock, Drag & Drop, Copy & Paste
Lock any slot to preserve its settings while browsing presets. Drag slots to reorder them, or right-click to copy and paste an effect configuration between slots.
