SERRAChainsaw distortion

The Swedish buzzsaw, rebuilt stage by stage: asymmetric silicon diodes in the feedback loop, an op-amp pushed into its rails, a germanium pair for the sputter, and the COLOR MIX gyrators that carve the saw. VINTAGE and CUSTOM modes, 7, 9 or 12 V supply, gate, TIGHT, blend, and its own cabinet for going straight to the desk.

The SERRA pedal: LEVEL, LOW, HIGH and DIST knobs above an orange chainsaw-and-sun panel, VINTAGE/CUSTOM switch and footswitch.

The line

Seven plug-ins that work as one rig. The pedals sit in front of the heads, MARÉ moves ECO over SOLIDIAN LINK, and every unit carries its own cabinets and mic placement.

The FORJA head: silver front panel with GAIN, BASS, MIDDLE, TREBLE, PRESENCE, RESONANCE and MASTER, channel switch and the Solidian sun on the grille.

High-gain valve head

FORJA

Three channels in one head, after the British super lead, the 80s master-volume head and the modern American lead channel. Voiced to sit behind SERRA.

  • EMBER, ANVIL and FURNACE: cascaded 12AX7 stages with cold clippers and each amp's own tone stack.
  • EL34 or 6L6 push-pull with sag and bias, and negative feedback through a 4x12 speaker load for PRESENCE and RESONANCE that behave like the real thing.
  • TS-style boost, gate and TIGHT in front for the d-beat and powerviolence tightness.
  • Modern and vintage 4x12 cabinets, positionable microphone, room and your own IRs.

The BASALTO pedal: black enclosure with MASTER, BLEND, LEVEL, DRIVE, MOOD and ENGINE knobs, GRUNT and ATTACK toggles and a six-band EQ with faders.

Bass pre-amp and drive

BASALTO

One pedal for the whole low end, from crust and powerviolence to modern djent clank. Seven engines, a split that keeps the lows clean, and a graphic EQ.

  • GRIT, BLADE, PUNCH, RUIN, VALVE and SWARM, plus DUAL, which runs PUNCH and RUIN in parallel and mixes them with MOOD.
  • SPLIT with Linkwitz-Riley crossovers: the low band stays clean and compressed while the drive takes the top.
  • One-knob compressor with an ALL IN mode, GRUNT and ATTACK pre-shaping, six-band graphic EQ.
  • 4x10, 8x10, 1x15 and a 4x12 guitar cab, on the drive path or the whole mix.

The DUNA head: tweed-coloured front panel with GAIN, FUZZ, BASS, MIDDLE, TREBLE, PRESENCE, DEPTH and MASTER.

Desert fuzz amplifier

DUNA

A valve head with a fuzz built in, made for stoner, desert rock and the warm, wide end of sludge.

  • 12AX7 preamp with grid current and the coupling and cathode capacitors, an exact passive tone stack and a power pair with sag.
  • Built-in silicon fuzz and three voices: VALLEY, RIDGE and TUNDRA.
  • Four synthesised cabinets plus your own IR, saved inside the session.
  • Positionable microphone and a stereo room.

The SIROCO pedal: orange enclosure with VOLUME, TONE, FUZZ, BIAS, MIDS and BLEND knobs above a desert sunrise panel.

Fuzz pedal

SIROCO

Three fuzz circuits in one orange box, with the guitar's volume knob modelled in front so it cleans up the way a real fuzz does.

  • Two-transistor germanium, four-stage MUFF with exactly solved diodes, and OCTA for the upper octave.
  • BIAS and supply voltage, down to the dying battery.
  • MIDS control and a latency-compensated blend for keeping the attack.

The ECO pedal: teal enclosure with FEEDBACK, DELAY and BLEND knobs, GAIN, RATE and DEPTH, tap and bypass footswitches.

Analogue echo

ECO

A bucket-brigade delay modelled down to every clock tick, so time changes bend the pitch and long repeats darken like the chip.

  • Compander with its gain carried through the buckets, triangle and square modulation.
  • Tap tempo with six subdivisions and host sync.
  • LOW CUT, TONE and DRIVE inside the feedback loop, AGE, WIDTH and trails.
  • Expression input: let MARÉ move any control over SOLIDIAN LINK.

Includes
MARÉ
The MARÉ expression pedal.

MARÉ is included. An expression pedal that also runs as an LFO or an envelope follower, with range, curve and smoothing. It moves ECO over SOLIDIAN LINK and sends MIDI CC to anything else.

MARÉ moving ECO

Built like hardware, measured like software

Every circuit is solved sample by sample, then checked: aliasing, latency, CPU, clicks on every control and the behaviour at any sample rate.

8×

Oversampling for offline renders, with 2×, 4× and 8× live, all relative to 48 kHz so a preset sounds the same at any sample rate.

6 smp

Fixed latency on BASALTO at 48 kHz. ECO and MARÉ add none at all.

ADAA

Antiderivative anti-aliasing on the clippers, so the top end stays clean when the gain is up.

Level 10

Every plug-in passes pluginval at its strictest setting before release.

Try before you buy

14 days, full sound

Every paid plug-in installs as a trial. Play it in your sessions, render with it, run it through your own rig.

  1. Install

    One installer per system with every Solidian plug-in. Nothing to register.

  2. Play for 14 days

    Every control, preset, cabinet and oversampling mode works, with no noise and no nag screens.

  3. Then a short silence

    After 14 days the plug-in drops out for a moment once a minute. Your sessions keep loading and your settings stay.

  4. Activate

    Paste the licence key from your Gumroad receipt into the plug-in. The same install becomes the full version.

Questions

Anything else, write to the address on your Gumroad receipt.

Which hosts does it run in?

Any host that loads VST3 or AU on macOS, VST3 on Windows, or VST3 and LV2 on Linux: Studio One, Logic Pro, Ableton Live, Reaper, Cubase, Bitwig, FL Studio and more. Each plug-in also runs as a standalone app for practising.

Pro Tools?

Not yet. AAX needs a separate certification from Avid, and it is on the list after the iPad versions.

How many computers can I use?

Your licence key activates up to three of your own computers at the same time, so the studio Mac and the laptop are both covered.

Are updates free?

Every 1.x update is free and arrives through your Gumroad library, where you can download the latest installers at any time.

How do I pay?

Checkout runs on Gumroad with card or PayPal. Your receipt carries the licence key and the download links.

Can I use the presets on records I sell?

Yes. Anything you record with Solidian is yours, with no credit or royalty owed.
