About This Item
Description
The H90 Dark is the same two-engine Harmonizer that anchors serious pedalboards, finished in a limited all-black enclosure: two of its 74 algorithms run at once, and the two inserts can sit anywhere in your rig.
The H90 Dark is a limited edition of the H90 Harmonizer. Functionally the two are the same platform: the same 74-algorithm library, the same dual-engine Programs, the same four inputs and four outputs, the same routing and the same 12V power requirement. The difference is the black finish and the limited production run. The library covers all 52 H9 Max algorithms plus 22 newer designs such as Polyphony, Prism Shift, VocalShift, PolySynth and the granular Cosmic Web, Glitch, GrainMod and Stutter.
Why guitarists choose the H90 Dark
- Two algorithms run simultaneously in every Program, in series or in parallel, which replaces two separate pedals and the patching between them.
- Two inserts (two mono or one stereo) can be placed independently anywhere in the signal chain, so one half of the H90 can sit in front of the amp while the other lives in the effects loop.
- 74 algorithms cover reverb, delay, modulation, pitch shifting, harmonizing, granular, synth and distortion effects.
- Spillover between Programs, adjustable from 0 to 30 seconds, keeps reverb and delay tails alive across a change.
- Dual routing processes two independent stereo signals, and the four inputs and four outputs suit four-cable-method rigs without an extra switcher.
- H90 Control edits Programs, presets and User Lists from macOS or Windows over USB-C, or from macOS and iPad over Bluetooth.
- The limited black finish sets it apart on stage while it behaves exactly like the standard model.
Controls
- Three footswitches Program changes, Preset and insert bypass and tap tempo; up to six footswitch functions in PERFORM mode with external aux switches.
- OLED display, five push knobs and seven LED buttons Show both running algorithms and give direct access to their parameters, with Quick Knobs and a PERFORM HotKnob.
- Exp/Ctl 1 and 2 Two 1/4" TRS jacks for expression pedals, aux switches of up to three buttons each, or CV.
- Routing Series or parallel algorithms, Insert routing for external pedals, or Dual routing for two separate signal paths.
- Built-in tuner
Connections & Power
- Inputs 1-4 and Outputs 1-4 1/4" TS mono jacks, instrument or line level.
- MIDI In and MIDI Out/Thru 5-pin DIN.
- USB Type-C USB 2.0 for control, updates and MIDI.
- Power 12V DC center-positive, 1 A, 5.5 / 2.5 mm barrel. Typical 9V pedalboard outputs (center negative, a few hundred mA) are not suitable; use the included universal supply or a 12V center-positive output rated 1 A or more.
- Bypass Selectable per setup: Relay bypass connects the inputs directly to the outputs with physical relays (true bypass, no tails); DSP bypass keeps the signal in the processor so tails ring out. In Dual routing, Relay bypass is available on Path 1 only. A global Kill Dry setting covers parallel-loop use.

FAQ
Is the H90 Dark different from the standard H90? Not functionally. It is a limited edition of the same platform in an all-black enclosure, with the same 74 algorithms, the same routing and the same specifications.
Can it run two effects at once? Yes. Every Program loads two of the 74 algorithms and runs them together in series or in parallel, and the two inserts can be placed at different points in your rig.
Will a 9V pedalboard supply run it? No. It needs 12V DC center-positive at 1 A on a 5.5 / 2.5 mm barrel. Typical 9V pedalboard outputs (center negative, a few hundred mA) are not suitable, so use the included universal supply or a 12V center-positive output rated 1 A or more.
Is it true bypass? Bypass is selectable. Relay bypass connects the inputs directly to the outputs with physical relays (true bypass, no tails), while DSP bypass keeps the signal in the processor so tails ring out. In Dual routing, Relay bypass is available on Path 1 only.
How do I edit it from a computer or iPad? H90 Control edits Programs, presets and User Lists from macOS or Windows over USB-C, or from macOS and iPad over Bluetooth.
