Kilpatrick Audio REDOX Reverb Now Available To Pre-Order

Kilpatrick Audio shared this video demo of their new REDOX reverb, originally introduced at the 2018 NAMM Show.

The REDOX is a hardware stereo algorithmic reverb processor that they say is ‘designed from the ground up to be a companion for electronic musicians and producers’.


  • Stereo algorithmic reverb with high dynamic range processing
  • Many reverb algorithms to choose from, including:
    • Kilpatrick Audio’s Lush Puppy algorithms great for fast synths, drums and guitar
    • Classic old-school reverbs perfect for old-school synth sounds
    • Multi-tap delay effects with a selectable number of taps
    • Smooth hall and room types perfect for vocals and instruments
    • Super long and smooth reverbs perfect for creating ambient textures
  • MOD effects work along with reverbs for creative results
  • Adjustable predelay on all reverbs up to 200ms
  • Pristine analog audio front-end with 24 bit converters and >100dB dynamic range (ADC to DAC)
  • High dynamic-range floating point signal processing prevents internal clipping
  • Low-latency signal processing of around 1ms
  • High-quality LCD screen shows settings and metering
  • Quick-access parameter controls for MOD control, reverb filter and size
  • 1/4″ line audio jacks using high-quality Neutrik connectors
  • MIDI control of all functions via USB or DIN MIDI
  • MIDI hardware THRU jack for daisy-chaining
  • Internal memory for storage of up to 99 presets plus live settings – free preset upload/download tool
  • 5V USB powered, draws less than 250mA – great for portable use
  • Integrated 100x100mm VESA mounting holes permits secure mounting using standard hardware
  • High quality USB cable and power supply included

  1. What an elegant and effective design!! I like the layout, but if that hardware or form factor was used for another product (like a multi-effect), I think I’d like a cursor diamond or some way to navigate pages. Seems like they’ve kept the UI pretty simple & efficient!

    1. I was thinking since when did USB power become a standard in audio equipment, and why not put this in a regular 19″ rack unit? Then I saw your comment, so clearly this is an attractive form factor.

      1. There seems to be a general move away from 19″ rack. Maybe it is seen as old fashioned. On the plus side it is easier to fiddle with a table top device. But there’s a small limit to how many things can go on a table top.

        1. I really dislike the desktop synths, effects, and audio interfaces. We don’t tend to spend a lot of time fiddling with reverb. Lots of people just browse presets until they find something they like, and even those of us who like to tweak will generally set it and forget it. So maybe it doesn’t always need to be one of the things on your desk, within arm’s reach. In fact, if all the effects and processors and modules and interfaces I need for a typical single track were boxes like this that sit on my desk, I would need a couple more desks.

          For a product like this, I can also see the argument against – nowadays most reverb comes from software plug-ins, and the rack experience doesn’t really offer much in contrast to that. Unfortunately desk space is precious and I already have too much gear competing for it.

  2. This thing looks really cool and I’m curious how it will stack up with its competitors (Strymon, Empress, Ventris) because I will be investing in one in 2019.

    I’m also intensely interested in the compressor they are working on (same form factor).

  3. I understand that traditional rackmount hardware is sort of a dead format in electronic music, because people want their gear to be more hands-on nowadays.

    But I still like the benefits of using a consistent format, rather than KORG making volcas and Roland making boutiques and people like Kirkpatrick doing their own thing.

    A good compromise is the Mother 32 approach – use Euro or 5U, so they can be integrated into modular systems, but make them also work as standalone desktop gear. Best of both worlds!

    1. Agreed. The M32 is a similar form factor as the old Electrix (Repeater, etc) modules. Worked great for table top but absolutely happy to sit in a rack.

  4. Sounds great, but I think would have been a guaranteed sale if that hideous blue LCD had been swapped for a yellow-on-black OLED. Now it’s all I can think about.

    1. You don’t need a computer for USB power. Several manufactures make USB wall warts. They even have wall mounted faceplate outlets that replace standard wall outlets if your so inclined, with USB ports. I for one, do not power anything via USB from my computer if I don’t need it also controlled by or controlling my computer applications. Your computer has bigger tasks, like powering its CPU vs Coffee warmer, desk fan…

      1. You don’t even need a wall wart. I have no shortage of USB cables and the little square power to USB adapters that are exactly the size of an outlet. I second the reluctance to connect USB gear to the computer just for power – I’ve actually picked up noise doing that with gear from certain big-name corporations that should know better.

  5. I think there are stricter rules for manufacturing and exporting goods with internal power. Using USB power means you dont need to go through such requirements and is cheaper and easier for smaller manufacturers. Also this is why it easier to make something a Eurorack module and not standalone… you are not responsible for mains power supply.

  6. +100 for USB power. USB bricks are cheap, powerful and easy to carry around. In a world where most of us are on our Nth phone, there are lots of USB outlets and cables in our junk drawers. I wish everything were USB powered.

  7. Sounds fantastic so far and I guess that’s all that really matters. Some stiff competition out there though. Looking forward to hearing more demos.

    Would really like to have seen a 4th knob dedicated to mod-speed (and/or depth).

    As a dedicated ‘synth’ reverb, maybe they’ll consider adding dual mono algorithms at some point. Tight and splashy on drums, epic and wandering on a lead.

    Big love for USB power and a real MIDI THRU port. Full MIDI CC control too! Manual is here:
