Press Release: Cali76 Stacked Edition & SlideRIG Compact Deluxe Mk2

Origin Effects Unveils Two New Dual-Chained Compressor Pedals

Cali76 Stacked Edition and SlideRIG Compact Deluxe Mk2 join Origin’s celebrated range of studio-grade stompbox compressors

Oxfordshire, UK (3rd May 2019) – Origin Effects has introduced a pair of new compressor pedals. While the updated SlideRIG Compact Deluxe Mk2 brings additional levels of adjustability to the SlideRIG design, the new Cali76 Stacked Edition takes Origin’s signature dual-chained compression into uncharted territory. Daisy-chaining a pair of outboard compressors together is an old studio trick made famous by Lowell George of Little Feat, who achieved his legendary, endlessly sustaining slide guitar sound by recording straight into the desk via first one Urei 1176 and then another. This was the inspiration behind the original SlideRIG, as used by everyone from David Gilmour to Joey Landreth.

Just like previous SlideRIGs, both of these new pedals feature the same painstakingly designed discrete Class-A circuitry found in Origin’s flagship Cali76 compressor. With two of these studio-grade, 1176-style compressors squeezed into one compact stompbox, they
deliver ultra-quiet, effortlessly musical, two-stage FET compression and gorgeously clean, singing sustain. This time, however, Origin have added new controls to provide easier access to an even wider range of tones.

In essence, the Cali76 Stacked Edition is the missing link between the Cali76 and SlideRIG ranges. A brand-new control – the gold ‘Thru’ knob – determines how much signal is fed from the first compressor to the second. Incredibly simple to use, this control allows the Stacked Edition to deliver not only single-stage Cali76 and dual-stage SlideRIG sounds but also everything in between.

Independent LED VU meters let you see exactly how hard each stage is working, while each of the compression stages features its own combined Attack/Release control. With the Cali76 Stacked Edition, you can combine two distinct flavours of compression – one to add sustain and fullness and the other to subtly limit any stray peaks, for example – or max out both stages for a super-sensitive, ultra-sustaining “clean overdrive” effect.

The same combined Attack/Release control has also been added to the SlideRIG Compact Deluxe Mk2. With one knob, users can simultaneously adjust the response of both compression stages, changing the initial transient of each note from glassy and percussive at one extreme (slow attack, fast release) to smooth and uniform at the other (fast attack, slow release). The range of this control has been carefully tuned to optimise signal-to-noise ratio and avoid any undesirable distortion artefacts, even at extreme levels of compression, so you don’t need to be a studio technician to dial in killer dual-compressor tones.

Both pedals are available to order now from Origin Effects dealers worldwide and direct from

Key Features

Cali76 Stacked Edition (£329/US$379/€379/AU$599):
Housing two Cali76 compressors chained together, the Stacked Edition features the same signal path as the SlideRIG but offers more control than ever before. With input level, output level and dry blend knobs, separate attack/release controls for each compression stage and the new ‘Thru’ knob to set how much signal is fed from one stage to another, it’s a Cali76, a SlideRIG and everything in between.

SlideRIG Compact Deluxe MK2 (£299/US$349/€349/AU$529):
The latest evolution of Origin’s unique dual-chained compressor. The Mk2 makes the complicated business of setting up two compressors in sequence incredibly easy, delivering
awesome slide tones and endless clean sustain that’s perfect for slide. The new Attack/Release control adjusts both compression stages simultaneously, offering a continuous
sweep of attack and release characteristics with no unpleasant artefacts.

    Hey Simon, this is all great… so in a nutshell, the new Cali 76, is like an extended slide rig.. with better control? It’ll give me the slide rig sound plus I can use it on my bass, etc… ? If so.. can I buy this from you or do I need to seek out a intermediary?

    • origineffects

      Hi, Harold.

      I’m glad that you like what you see and hear!

      Your analysis is pretty spot on. You can buy the Cali76-SE from our website or from one of our dealers.


  • Silas Feemster

    So I am a long time user of both pedals on my board. since releasing the stacked Cali why not ad a either or switch??? It would save even more room!!

    • origineffects

      Sounds like a good idea, Silas! That being said, we would need to make the pedal wider to accommodate the extra footswitch so it might end up nearer the size of two pedals anyway.

      • William Muhovich

        What about a remote switch jack that turns the 2nd stage on/off? Same could apply to Cali76SE and Sliderig Mk2, I think. Maybe a Thru cutoff to turn on/off that 2nd comp circuit?

        • origineffects

          Good idea. The current Compact series enclosure doesn’t accommodate an extra jack though so it would require a redesign.

  • Mattias

    Can you in short give a detailed answer of how to choose between these two pedals?
    What are either better at than the other?

    • Adam Wilshire

      Hi there! Thank you for your comment. Essentially the SlideRIG is designed for quick easy access to super-long sustain. The ideal compression settings for slide players. If you plan on using the compressor mainly for slide playing, then this pedal will be ideal for you!

      The Stacked Edition is more tweakable with the ability to control how much signal is fed from the first stage of compression into the second. You also have individual Attack/Release controls for both stages of compression. This is useful for setting up the two stages of compression differently. For example, one compression stage for gentle dynamic control and the second stage for limiting peaks. This pedal is aimed at those who want further control and the best of both worlds from the Cali76 & SlideRIG compressors.
