Eventide Eclipse

Eventide

The Eclipse V4 is the last rack unit that treats stereo reverb like a physical space—not a post-processed illusion.

A professional-grade digital effects processor with dual independent effects blocks, nearly 100 algorithms—including 11 reverbs—and 24-bit/96kHz conversion. Supports true stereo reverb I/O and extensive looping (up to 20 seconds per block). Firmware updates require Compact Flash and strict version dependencies; bootloader corruption requires factory reprogramming.

Chapters & takeaways4
  1. 1:00
    Stereo as standard

    True stereo reverb I/O and 24-bit/96kHz conversion are baked into every reverb algorithm.

  2. 2:56
    Dual blocks, not just dual presets

    Two independent effects blocks let you loop on one while adding reverb or delay on the other.

  3. 4:37
    Looping that doesn’t lock up the rest

    20-second mono loops, 10-second dual loops, reverse modes—all with zero latency penalty on the second block.

  4. 6:12
    Update or risk factory repair

    Firmware updates require Compact Flash—and a bootloader misstep bricks the unit.

Worth your time?

Yes. Use the whole thing.

3.5/ 5
What works
  • true stereo reverb I/O
  • 20-second mono loops with second block fully available
  • dual routing for independent processing paths
What does not
  • support USB or modern update methods
  • allow simultaneous multi-algorithm chaining without manual routing
  • include built-in preset library management
Use it if
  • studio engineers needing parallel reverb + delay chains
  • live performers using one block for looping and the other for spatial texture
  • anyone who prioritises 24-bit/96kHz conversion and true stereo reverb I/O over convenience
Skip it if
  • beginners
  • laptop-only producers
  • anyone unwilling to manage Compact Flash firmware updates
The written brief2 min read

What it is and what it was built for

A compact 1U digital effects processor built for studio engineers and live performers who need two independent, high-resolution effects paths in one box. It was built for flexibility: dual routing, true stereo reverb, and deep looping—not for synthesis, sequencing or DAW integration.

How it works, in terms a player would use

It runs two independent effects blocks. Each block holds one algorithm. You route audio to either block—or both—using dual routing configurations. Looping uses 20 seconds per block. When looping on one, the other stays free for reverb, delay or texture. You update firmware via Compact Flash card or serial cable—but only after installing V3.51 if coming from earlier than that.

What it does better than anything else

It delivers true stereo reverb I/O—no mono-in/stereo-out compromise. It gives 20-second mono loops and 10-second dual loops while keeping the second block fully available for parallel processing. It is the only effects processor in its class with 24-bit/96kHz conversion at launch.

What it does badly

It does not support modern update methods. Interrupting a bootloader update corrupts the ROM permanently. It offers no USB, Ethernet or wireless connectivity. There is no built-in preset management beyond the hardware interface. It cannot run algorithms simultaneously across blocks in a single chain without manual routing.

What people made with it

The sources do not state what people made with it.

Who should use it, and who should not

Studio engineers needing parallel reverb + delay chains. Live guitarists or keyboardists using one block for looping and the other for spatial texture. Anyone who values 24-bit/96kHz conversion and true stereo reverb I/O over convenience. It is not for beginners, laptop-only producers, or anyone unwilling to manage Compact Flash firmware updates.

Is it worth your time

Yes—if you need true stereo reverb I/O and dual-loop flexibility in a 1U rack unit. No—if you rely on modern USB workflows, cloud updates or touchscreen editing. Its bootloader update risk and CF-card dependency make it high-maintenance by current standards.

Electro-Harmonix Memory ManElectro-HarmonixThe Electro-Harmonix Deluxe Memory Man is an analog delay pedal introduced in 2008, offering up to 550ms of delay, selectable chorus or vibrato modulation, true bypass switching, and mono audio I/O.

Eventide SpaceEventideThe Eventide Space is a reverb-and-delay pedal offering 12 algorithmic spatial effects—including Hall, Plate, Blackhole®, and Shimmer—controlled via 10 knobs, MIDI, expression pedal, or HotSwitch. It features 100 presets (some artist-designed), true analog bypass, tap tempo/MIDI clock sync, and mono/stereo I/O in a rugged metal pedal format. Software tools FactorLib and H9 Control manage presets; the SpaceTime algorithm combines modulation, two delays, and reverb.

Big MuffElectro-Harmonix · 1969The Big Muff Pi is a 1969 fuzz effects pedal with four transistors, two soft-clipping stages, and a tone stack that scoops mids when centred. It delivers smooth, saturated, bass-heavy sustain at any volume—making small amps sound bigger. It was intended to mimic Hendrix but became heavier and more distinctive. It does not offer gain staging, midrange recovery, or dynamic clean-up.
