120mA @9V, 2.1mm centre-negative. No internal battery connection.
Supply voltage can be in the range of 9V – 18V DC for the compact compressor range. 18V will give the most headroom, allowing for higher levels of compression before clipping occurs. All compact compressors accept a 2.1mm centre-negative connection and do NOT feature a connection for an internal battery.

Cali76-TX & TX-L 13mA @9V, 72mA @18V
Cali76 Standard 13mA @9V, 22.5mA @18V
SlideRIG 10mA @9V, 19mA @18V

All large format compressors accept a 2.1mm centre-negative connection.
The Cali76-TX and Cali76-TX-L pedals can be powered by a 9V PP3 battery but this will bypass the transformer output stage – causing the unit to behave like the original Cali76 Standard. Powering these pedals with a supply below 12V will also cause the transformer stage to be bypassed.
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 any 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.
Our Origin Effects compact pedals are designed to be accepting of a range of power supplies, whilst delivering impeccable performance. On paper, any power supply which meets our pedals’ specifications will be suitable, however, if the supply doesn’t have sufficient internal filtering then unwanted noise may be heard. Here is a list of power supplies which we have used with our compact pedals and we can recommend for use with our pedals:
- Voodoo Labs Pedal Power series
- Cioks supplies
- Truetone 1 Spot Pro series
- Strymon Zuma
- Dunlop ECB-004
100mA will be perfectly adequate for the Cali76-C & SlideRIG-C models. In the case of the more thirsty, Cali76-CD, Cali76-CB & SlideRIG-CD, we suggest using a DC supply with a current rating in excess of 100mA. In the case of Voodoo Lab, Strymon Zuma, Truetone and Cioks supplies, a 100mA rated output will be fine under normal operating conditions.
We always recommend using a regulated power supply for noise and reliability considerations. Having said that, the compact units feature a voltage-limited, floating regulator which will help clean up some of the noisier supplies out there, as well as reducing the risk of failure due to plugging in the wrong supply. It should be noted that while linear-supplies noise can be filtered relatively easily, certain switch-mode supplies can be highly problematic due to noise artefacts that extend well into radio frequencies.
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 and the RevivalDRIVE, 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.
The compact compressors have an input impedance of 1.1M Ohms and can handle input levels of up to +12.5dBu.
Unfortunately, we don’t offer modifications or custom electronics work. Back in our early days when Origin Effects was just a one-man workshop, Simon was occasionally able to modify pedals and make one-off designs. However, as the business has grown, Simon’s time is now fully taken up by the production of current models and developing our new and aspirational designs.
We currently have no plans to reintroduce any of our discontinued models in the foreseeable future. The large format 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!
Attack times are: 0.020mS to 1.7mS (for 100% of recovery). Double the range when compared to the 1176 (stock 1176: 0.02mS – 0.8mS). This further defines percussive transients.
Release times are: 32mS to 267mS (for 63% of recovery).
The threshold level is -6dB at the lowest ratio setting (4:1) and -4dB at the highest setting (20:1)
Low-frequency hum is usually caused by ground loops but can also be experienced by interference from electrical supplies.
Be sure to check the pedal with different guitars, cables, amps, on different spots on (and off) your pedalboard, and with/without other pedals connected (even if they’re not in the signal path). Because compressors boost low-level signals it can seem as though the pedal is producing the hum, because it is only audible when the effect is engaged, however, it may be that the pedal is simply boosting an existing noise issue elsewhere in your signal chain.
High-frequency, whining noise is usually produced by a switch-mode power supply.
If you are still struggling to cure noise in your signal chain, please get in contact with us and we’ll be happy to assist you in finding a suitable solution.

How do I find my pedals serial number? Your pedals serial number can be found either on the original box or, on the pedal front panel near the footswitches.
