There's going to be a bit of variation from unit to unit because pot tapers from pot to pot are never perfectly consistent - especially in log pots.  Unfortunately that's the nature of logarithmic pots.

For a grittier dirtier setting, try 10:1, release at 10oclock, and doing 15-20dB of compression, then maybe use the blend to mix to taste. You'll introduce some harmonics with this setting that will thicken things up a bit. It should be great for sustain too.


The Compressor MKII has a tilt style Eq knob and a switch for setting the cutoff frequency of the Sidechain Highpass Filter (off, 120Hz, or 240Hz).

The Bass Compressor has a knob to set the cutoff frequency of the Sidechain Highpass Filter (20Hz - 400Hz) and a Tone + Color switch which adds mild harmonic distortion with a mid range cut or an upper mid range boost (sounds great on everything, including guitar).

Our new compressors use 1/8" TRS jacks for the sidechain insert.  The tip is the send and the ring is the return.  This means the tip of the connected cable will send the audio out coming from the audio input of the compressor and will return the signal on the ring of the TRS cable.   The send is handy if you want to insert an effect into you compressors sidechain.  

If you want to insert an external signal for sidechain compression you would want to use a breakout cable and ignore the tip side of the cable as you want your external signal going to the compressor on the ring.  

 

Here are a few cables you could use to achieve this:

https://hosatech.com/products/analog-audio/stereo-breakouts/hosa-breakouts/ymm-261/ - Great for connecting a phone, modular or other 3.5mm cable

https://hosatech.com/products/analog-audio/stereo-breakouts/hosa-breakouts/cmp-150/ - Good for inserting another pedal into the sidechain or a signal that uses 1/4" jacks.  

 

If you plug a TRS cable directly to the sidechain insert from a device that is sending a signal on both the ring and the tip, when using a phone or a laptop for example,  you may experience the audio bleeding from the phone to the compressors output.  Connecting to the ring of a stereo breakout cable connected would solve this issue.


General

All compressors work by turning down the loud parts of your playing, then to get the average level back to normal you have to turn the whole signal up. The benefit of this is that you get longer sustain, and more even dynamics to your sound. Unfortunately, this also turns up any noise that comes into the compressors input. The Empress Compressor is already designed to have quite low internal noise. One possible way to improve the overall noise is to use the compressor early in your pedal chain before any other more noisy effects you use.


Mods

Step 1

Remove the screws from the bottom of the enclosure, and take off the back plate.

Step 2

Right away, you'll see a ribbon cable connecting two circuit boards that are locked in place by two beige connectors. To unlock these connectors, gently pull up on the black upper part, and slide the ribbon cable out.

Step 3

Insert the new ribbon cable into the unlocked connector on the bottom circuit board as shown. The pins should be facing toward the jacks, and the circuitry should be facing upward and away from the user as shown. Make sure it's nice and flat to the bottom of the connector, and then lock it into place by gently pushing the black mechanism back downward.

Step 4

Insert the other end of the ribbon cable into the unlocked connector on the upper circuit board as shown. This time, the pins should be facing downward. Again, ensure it's fully inserted and flat to the end of the connector, and then lock it into place.

Step 5

That's it! Replace the bottom plate and screws and get back to rockin'!

Only the first run of Bass Compressors have a noise issue.  If your Bass Compressor is above serial number 240(silver) or 260(blue) then your compressor should not have any issue with the LED clicking noise.  If you are experiencing a clicking noise with your compressor please email support@empresseffects.com for a fix.  


This is not an issue with the Compressor MKII on any serial numbers, only the Bass Compressor. 


The colour circuit can be bypassed in either or both tone switch positions via internal dipswitches. When you open the pedal the switch is located just above and to the right of the stompswitch.  Depending on the compressor you may have a small piece of plastic covering the dipswitches that can be removed.  Move the top dipswitch to the left to disengage the colour circuit from the cut and move the bottom switch to the left to disengage colour from the boost.
