The flagship

Crucible

One screen. The whole board.

An entire pedalboard, rebuilt inside one device. The effects you would normally chain across the floor — overdrive, distortion, fuzz, wah, modulation and delay, each modeled on a classic — all run in the silicon at the same time, into a built-in cabinet simulation. Tap any pedal on the Crucible’s touchscreen to dial in its parameters, or shape everything from your desktop over USB.

Guitar in, tone out. Every effect runs in parallel inside the box — no serial chain, no stacking, no added latency.

Inside the fabric

All the popular effects.
No order to obey.

The pedals that defined a sound — each modeled on a classic and running in its own corner of the silicon, all at the same time. Stack them, A/B them, automate them from the editor.

Wah
Dunlop Cry Baby inspired

A sweeping resonant filter — vocal, expressive, worked with your foot.

Overdrive
Ibanez TS808 inspired

Warm, responsive grit that cleans up the moment you ease off.

Distortion
Boss HM-2 inspired

All knobs up for the Scandinavian buzzsaw — tight, high-gain, unmistakable.

Fuzz
Big Muff inspired

Hard-clipped, endless-sustain saturation that never lets go.

Tremolo
Boss TR-2 inspired

Amplitude swung from a gentle shimmer to a hard, throbbing chop.

Phaser
MXR Phase 90 inspired

Sweeping notches for liquid, swirling motion.

Chorus
Boss CE-2 inspired

Detuned doublings that widen a single part into an ensemble.

Delay
Boss DD-3 / DD-8 inspired

Echoes from a tight slapback to long, trailing repeats.

What we do

A monolith you can open.

Obsidian is a hardware studio out of the AI Centre of Excellence at Shiv Nadar Institution of Eminence. We design professional audio electronics around FPGAs — then take them from breadboard to a board you can hold. Named for the monolith: a silent slab that changes everything around it.

01

Built in India

Designed, fabricated and assembled domestically. Studio-grade audio hardware engineered for the Indian market — and built to travel.

02

Prototype to product

Every board is verified by hand and certified against the fab’s real process before it ships. Breadboard to manufacturable, with the discipline to match.

The workbench

More on the bench.

The Crucible leads, but it isn’t alone. A bench of audio tools, instruments and machine-learning experiments, all built the same way.
