At the bottom of the FEATURES tab on each product page you'll find a Specification section. This shows the power supply requirements for that specific model.
Our original series of large format compressors feature switchable true-bypass and buffered-bypass modes utilising a three pole mechanical switch in the signal path.
In the case of the compact series of pedals, we’ve opted to go with a fixed buffered bypass scheme. This guarantees transparent signal transfer, correct pickup loading, reliability and noiseless switching.
True bypass relies on the use of more complex mechanical switches and/or relays which all generate small amounts of switching noise. Our pedals (particularly the SlideRIG) apply extreme amounts of gain and this tends to accentuate even the slightest of noise sources. In an effort to get ever closer to perfection we’ve chosen to opt for a switching system that places the switch outside of the signal path.
True-bypass is great when you want to be sure that a pedal is not colouring your tone when switched off. However, plugging your guitar into long cables and/or chains of true-bypass style pedals will result in some high frequency loss due to the inductance and capacitance of cable and wiring. Cheap patch leads are particularly bad in this respect. Buffered-bypass schemes will effectively drive the signal down your cables to maintain a full and natural frequency response.
If you require true bypass from a compact pedal, an external looper can be used.
We are unable to offer custom modification for our products.
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.
When adjusting the controls on the SlideRIG, parameters of both stages are adjusted simultaneously, for example, adjusting the ATT/REL will change both stages to the same times. The Cali76 Stacked Edition allows these parameters to be set independently from one another, for example, the ATT/REL for the first stage can be set fast/slow and the second stage can be set slow/fast.
The frequencies filtered out of the sidechain are 20Hz (most filtered) to 350Hz (least filtered). Turning the HPF control clockwise reduces the amount of these frequencies that trigger the compressor, making them relatively louder than frequencies above 350Hz.
The HPF is most dramatic on bass instruments such as electric and acoustic bass, piano and upright (double) bass, but can really help add punch and clarity to drop-tuned electric guitar.
Percussive Compression for Soloing into a Clean Amp (like a Fender Twin Reverb).
The initial transient of each note should leap out of the amp, especially when playing staccato runs of notes! I love the Allman Brothers and this setting really enhances the chimey tone of my SG when I play those Dickey Betts lines!

“TX” Rear Panel Switches: in downwards positions.
A FET compressor is a powerful form of compression, due to the fact that it can respond so quickly. However, this isn’t always a good thing and when used with guitar it’s very easy to select settings that result in audible distortion artifacts.
When compressing you’re essentially attacking the waveform, and so you must be careful not to gouge out large chunks! Dialing in high levels of Ratio, along with very fast Attack and Release settings WILL result in distortion. These distortion artifacts will get more audible on lower strings, and when playing complex “jazzy” chords. For this reasons it’s often best to offset particularly strong settings on one of the Attack, Release, or Ratio controls, by dialing in less extreme settings on the other two knobs.
Simon Keats (designer): “There’s a lot of confusion when it comes to using attack and release controls with guitar. Having happily typed a short novel to a customer (I’m ALWAYS happy to help) I thought I would share the knowledge…
“The release control cannot be used to increase sustain, but it can do good stuff…
“Fundamentally, a compressor will reduce the level of a loud signal, whilst in the case of the Cali76 & SlideRIG, also applying a degree of boost to quieter signals. When the compressor applies “gain-reduction” the loud signal is made to be quieter. Once the loud signal has been safely seen off the compressor will relax and return back to its normal state. The release control governs how quickly the compressor returns back to its normal state i.e. back to applying a degree of boost.
“A very fast release means that the compressor will react quickly and fully recover between all notes. Imagine a scale of loud staccato notes. With a fast release, the compressor will reduce the level of each note in an identical way, whilst fully recovering in time to address the next note in the sequence. The compressor will, therefore, balance out the level of each note against its neighbour! More than likely, you will hear the compressor quickly pump as the gain is modulated. Also, with a slow attack, the compressor will impart a satisfying percussive thud on each note!
“A slow release will mean that the compressor can’t return to its normal state before the next note is played. This means that in a scale of notes the dynamic relationship between adjacent notes is pretty much preserved. There is no “pumping” effect. In fact, everything sounds pretty natural! Note to shops: this is a crap setting to dial in when trying to demo an “exciting & impressive” compressor pedal! Though not as exciting, this type of setting is highly useful for ironing-out level differences between passages of playing, for example for balancing single notes lines against more energetic rhythm playing!”
Origin Effects compressor pedals are designed to be quiet and hum-free, however, the nature of a compressor is that it will amplify any quiet signal entering it. If noise or hum is entering your signal chain before the compressor it will become louder when leaving the compressor circuit.
Best practice is to place a compressor pedal before any devices which could be adding hiss, hum, or noise. Likely culprits are distortion-based effects such as overdrive, fuzz and distortion pedals.
Hum picked up by singlecoil pickups will also be amplified by a compressor pedal. Try your pedal straight into an amplifier with a humbucker-loaded guitar to see if the noise disappears.
All of our Cali76 pedals will distort when certain settings are combined – this is because each control has a broad range which makes the Cali76 useable with a variety of instruments (guitars, drums, vocals etc). The distortion can be described as a crackly, crunchy effect which can increase as the note fades out.
Setting the RATIO, ATTACK, and RELEASE controls near maximum will certainly produce distortion with electric guitar, especially on lower strings.
Try these settings to see if the distortion disappears:
OUTPUT 2 o’clock
INPUT 12 o’clock
This will occur when the unit is powered from a supply providing voltage between 9V and 18V. The relays inside the TX and TX-L models will switch at around 11V kicking in the transformer circuit; the relays can rapidly switch on and off if supplied with a voltage close to this.
Supplying the unit with less than 10V and more than 13V will ensure no relay flutterin
In designing the Compact Series pedals, Origin Effects has gone to painstaking lengths to preserve the build quality and sonic integrity of the original Cali76 and SlideRIG circuits, even improving on them where possible.
The reduction in size has been achieved by using a mixture of traditional through-hole and SMD components, spread across a pair of densely populated, stacked boards. The signal path utilises film and tantalum capacitors, carefully chosen low-noise transistors and rugged MELF resistors (essentially traditional through-hole resistors without the leads), which offer low-noise performance and rock-solid reliability.
One of the reasons why the original Origin pedals sound so good is that they deliver true FET compression, with a fast yet highly musical response that is a world away from the brutal and unforgiving sound of traditional VCA compressor pedal designs. The new Compact Series pedals stay true to Origin’s design philosophy with absolutely no opamps or VCAs used in the signal path.
The new pedals are powered by mains adapter only. Dispensing with the usual internal 9V battery option allows more space inside the enclosure for high-quality circuitry, while also supporting the high-current circuit design that is the key to these pedals’ astonishingly low noise levels.
The Noble Amplifier Company Preamp will only power the Cali76-TX in standard mode. Use one of the 9V outlets to power your Cali76-TX if using this preamp.
The transformer circuitry is switched in by relays when provided with 14.6V. If the -TX has powered up with the transformer engaged then dropping the voltage below 12.6V will switch out the transformer circuitry; the Cali76-TX will then perform like a Cali76 Standard.
We do not recommend using a supply of 12V – 15V as possible variation in regulation of mains voltage could cause the transformer stage to switch in and out of operation. 18V is recommended for best results when using the transformer output stage.
UPDATE: Noble Amplifier Company now offers an optional 18V boost cable to power the Cali76-TX at 18V directly from the Noble preamp. When using this cable the transformer will be engaged.
The easiest way to tell is by the serial number: pedals fitted with a Lundahl transformer have a letter “L” at the end of the serial number.
The hard way is to remove the pedal’s base and look for the transformer. If it’s black then it’s our own “Iron-core” TX and if it has a silver transformer cover that has Lundahl’s logo on it then, you guessed it, you have a TX-L.
We currently have no plans to reintroduce the TX-P or G-P Cali76 models in the foreseeable future. These models required expensive and difficult to source components, as well as a huge amount of man-hours to assemble, so sadly, didn’t prove to be cost-effective for us to keep producing.
Our highly sought after discontinued models do show up on eBay, Reverb.com, Craigslists etc, from time to time, so keep an eye out for a piece of Origin Effects history!
The RevivalDRIVE Hot Rod features more gain, a tweaked preamp stage and we’ve also changed the bright cap values. These changes were inspired by modified amplifiers of the 1970s, providing a slightly darker tone with a lot more gain.
The RevivalDRIVE Hot Rod is capable of recreating a variety of British and American hot-rodded amp tones. Please refer to the Getting Started Guide for example settings including a Randall Smith modified Princeton, a hot rodded Plexi, a Trainwreck style tone and a fully cranked Orange on-the-edge-of-explosion!
The RevivalDRIVE Hot Rod is voiced with a darker tone, suited to heavier sounds. The PREAMP and BRIGHT-CAP switch have been tweaked for the Hot Rod Edition.
Setting the RevivalDRIVE Hot Rod’s VOLUME control to 2 o’clock provides a similar amount of overdrive as a fully cranked RevivalDRIVE.
Our switcher interface box lets you connect to two ports on your ES5 (EXT CTL1/2 AND EXT CTL 3/4) and gives you control over the following four parameters:
- Channel Select
- Mid Boost
- Blend Override
The EXT CTL outputs on the ES5 use TRS connectors, so each plug controls two parameters. Our switcher interface box converts to our level sensing format which connects over a single TRS cable to the RevivalDRIVE.
Not all players need to control all four parameters remotely, and many are happy to use the local footswitches on the pedal, so we offer a special Remote Switcher Cable that gives you control over TWO parameters:
- Mid Boost
- Blend Override
The special cable is needed for compatibility with our level sensing format. It has two resistors built into it – details on how to build your own can be found here: http://origineffects.com/wp-content/uploads/2018/05/Custom-TRS-cable-drawing-angled.png?e5cc7f&e5cc7f
Another option that many users like is our dedicated Revival Footswitch, which lets you control Mid Boost and Blend Override. This is the normally the easiest way to add footswitches for these functions, but unfortunately doesn’t connect to remote switching systems.
The Revival Footswitch is built to work with our level sensing circuitry, and can be connected using any off-the-shelf TRS cable.
The rectifier stage in the RevivalDRIVE Compact is set to sound and feel somewhere between a silicon rectifier and a GZ34 valve rectifier.
In order to condense the circuit design of the original RevivalDRIVE to fit everything in a compact-style enclosure, we have had to leave out certain features. The circuitry which reproduced the mains power supply took up a lot of real estate, so we made the decision to not include and ghosting features on the RevivalDRIVE Compact.
With the original RevivalDRIVE we kept the aesthetics true to the non-master volume amps that the pedal was inspired by, labelling the gain adjustment knobs VOLUME. However, we have now renamed the volume control to ‘Gain’ to be more in keeping with modern amps and overdrive pedals.
More Gain = More Overdrive!
The POST-DRIVE EQ is very similar to the RE-AMP EQ on the original RevivalDRIVE. A three-way toggle switch tailors the output of the pedal to suit your amplifier, whether it is voiced bright, dark or flat.
The RevivalDRIVE Compact has a simple set of controls to quickly set the pedal to your amp. The RevivalDRIVE Standard offers further adjustment with a control to counteract the effects of an amp’s bright-cap, and the RevivalDRIVE CUSTOM offers an extensive range of controls which can be used to translate the vast range of amp tones in the pedal to even the most obscure amps.
We have included the ADJ control from the RevivalDRIVE Custom EQ Panel. This is a continuously adjustable filter that allows you to tweak the output of the pedal to fit your clean amplifier with ease.
The RevivalDRIVE Compact features a new interactive blend control. When you dial back the blend knob, the overdrive signal will clean up. The RevivalDRIVE Compact does have a high output gain and can be used as a boost to push your existing valve amplifier.
This time we have tweaked the range of the output control so that when the output is set all the way down, no signal will pass from the output stage of the pedal.
The RevivalDRIVE Compact does not feature a switchable preamp shape as original RevivalDRIVE does. In its place we have included a Highs control that provides continuous adjustment through a range of classic Fender and Marshall-style preamp voicings, progressively increasing mid-range and highs.
If solely the mid engage and blend override functions are required to be switched remotely, then our Remote Switcher Cable be used without the need for the Switcher Interface. The 4k7 ohm resistors inside this cable allow the switch to be partially closed which is enough for just the mid engage and dry override to be toggled.
Connect the Remote Switcher Cable from a control switch jack on the controller to the RevivalDRIVE’s F/SWITCH connection.
PLEASE NOTE: remote switching of the bypass state and active channel can only be achieved with the Switcher Interface.
You can use an external momentary switch to control the tremolo speed. Options include the Boss FS-5U or MXR M199 Tap Tempo switches.
You can also remotely toggle the tremolo function on and off via an external latching switch. This function requires using a TRS ¼” jack cable. The tremolo function is on when the ring is connected to the sleeve.
It is possible to achieve cleaner tones by keeping the DRIVE control at low settings and compensating for volume using the output control. Note that the tremolo effect becomes more interactive with higher DRIVE settings, making the tremolo effect less intense when picking harder.
The MULTI switch multiplies the speed of the tremolo effect by x1, x2 and x3.
The switch can provide 3 different ranges on the SPEED control or it can be used to change how the tapped tempo relates to the tremolo speed.
When a tap tempo footswitch is used, the tremolo speed can be set to be the same as, double or triple the tapped-in tempo.
The SHAPE switch offers the choice of a smooth sine wave and a pulsating full-wave shape. The sine wave is modelled on the classic brownface-style tremolo whereas the full-wave setting delivers a more intense tremolo effect.
