paraeq MKII Deluxe Equalizer and Boost Pedal User Manual
Introduction
When we released our original ParaEq back in 2009, it quickly became a favourite among musicians who were searching for something more than the typical oversimplified controls found on most Eq pedals. Now, based on our users’ valuable feedback, we’ve taken everything great about our original ParaEq and made it even better.
The Empress ParaEq MKII Deluxe is designed to be a tool for sweetening the
tone of any instrument. We’ve designed it to give musicians a powerful,
musical, high quality Eq in a conveniently small package. The signal path is
comprised of the highest quality components chosen for their transparency,
powerful tone shaping capabilities, and low operating noise. We’ve increased
the headroom to 27V, similar to rack-mount equipment, to ensure clarity of
sound no matter how hot the signal. With added filters and Q knobs allowing
for precise parametric control, the ParaEq MKII Deluxe allows for ultimate
tonal shaping. Oh, and the whole package is now half the size. Who doesn’t
love a small package?!
With the Empress ParaEq MKII Deluxe, your instrument will still sound like
your instrument, only better, and with more control than ever before.

Sample Applications
General Sweetening: Perhaps you really like the tone of your guitar but find it could be a little brighter with more high end detail. With the ParaEq MKII Deluxe, adding a small boost in the range of 3 kHz to 5 kHz with a wide Q will add a bit more detail, while still retaining the sound of your instrument. In a similar manner, adding a wide Q boost to the low frequency range will warm up your instrument’s sound.
Tone Correction: Say you’ve set your amp up in a venue and find that the acoustics of the stage are making it sound too boomy. By cutting some of the frequencies in the low mids (200Hz– 600Hz) with a medium width Q, you can minimize the negative effects of the room acoustics on your sound.
If you find your guitar isn’t cutting through the rest of the band, you can boost the upper mid frequency range (1kHz–4 kHz) instead of simply turning up the volume of your amplifier, which could lead to you just drowning out the rest of the band.
Feedback Zapping: With a DI’ed acoustic instrument, playing live at stage volumes can sometimes be a nightmare. Feedback through monitors can quickly ruin a great performance. By using the ParaEq MKII Deluxe’s mid and hi frequency bands and narrow width Q settings you’ll be able to cut the frequencies causing the feedback while retaining much of your instruments sonic signature. The narrow width Q setting ensures the range of frequencies being reduced is very small, preventing your instrument from sounding dull or muddy.
Distortion Enhancement: Having the ParaEq MKII Deluxe before your amplifier lets you use it to shape your distortion sounds in radical ways. For example, if you want the treble of your signal to distort a little more you can boost the high frequency band before it reaches your amplifier. This lets you add a little sonic slicing capability to your sound without muddying up your bottom end. The boost control on the ParaEq MKII Deluxe is a great way to push an already cooking tube amplifier into musical overdrive.
Q Controls
The Q is a measurement of how much the Eq band affects a range of frequencies.
Tight or Narrow Q : Knob fully CW. This setting is best for attacking problems. For example, if you have an acoustic instrument feeding back, a tight Q will allow you to cut the offending frequency without affecting the frequencies around it.
Medium Q : Knob at 50%. This setting is great for general tone shaping. Most equalizers in instrument amplifiers are medium Q. Try using this setting to cut frequencies in the 300Hz-400Hz range if your amp is sounding a little muddy, or boosting in the 1kHz-5kHz range if your guitar is a little dark.
Wide Q : Knob fully CCW. Wide Q settings are best when you want a really transparent change to the signal. For example, boosting at around 100Hz can add a bit of warmth, and a little boost in the 3k range can add detail and definition, all while retaining the original tone.
HP and LP Filters
High-pass and low-pass filters are used to remove specific bands of frequencies from the sonic spectrum. These bands are determined by the filter shape and the cut-off frequency at which the filter is set.
High-Pass Filter : The high-pass filter attenuates frequencies below the
cut-off frequency set by the knob, which ranges from 10Hz to 330Hz, by
12dB/octave.
Low-Pass Filter : The low-pass filter attenuates frequencies above the
cut-off frequency set by the knob, which ranges from 1.5kHz to 22kHz, by
12dB/octave.
Shelving Filters
Shelving filters are used to boost or attenuate a specific band of frequencies from the sonic spectrum. The filters’ shape and amount of gain/attenuation applied determines the filters frequency response. The ParaEQ MKII Deluxe shelving filters are extremely gentle and musical sounding baxandall filters.
Low-Shelf Filter : Very gentle slope that boosts or attenuates
frequencies below 200Hz by -15dB to +15 dB, depending on the knob position.
High-Shelf Filter : Very gentle slope that boosts or attenuates
frequencies above 1kHz by -15dB to +15 dB, depending on the knob position.
Advanced Configuration
Advanced Configurations are used to control the bypass and boost states of the ParaEq MKII Deluxe.
Entering the advanced configuration: Unplug the power from the pedal. Plug the power back in while holding down both the boost and bypass stomp switches. The LEDs should flash momentarily to confirm that you are in the advanced configuration.
Modifying the advanced configuration: To toggle between true bypass and
buffered bypass use the
bypass stomp. The bypass LED will display which mode you are in:
- Bypass LED off = true bypass (default)
- Bypass LED on = buffered bypass
To toggle between normal bypass mode and independent bypass mode use the boost stomp switch. With independent mode you can apply boost without having the equalization engaged. This makes it almost like having a separate Eq and boost pedal each with their own bypass switch.
- Boost LED off = normal (default)
- Boost LED on = independent
Exiting the advanced configuration: Hold down both the tap and bypass stomp switches. The bypass LEDs will blink momentarily to confirm the ParaEq MKII Deluxe has exited the advanced configuration.
Frequency Region Descriptions
Here’s a rundown of different frequencies that should be helpful when using the ParaEq MKII Deluxe to achieve a specific end result.
Electric Guitar
- 80Hz – 150Hz: Boosting can add a subtle warmth and bigness to the sound. Cutting can bring down any rumble you’re experiencing.
- 150Hz – 400Hz: Cutting in this region can remove a bit of mud, and boosting will bring out the warmth.
- 400Hz – 800Hz: Cutting in this region can make the sound more pristine. Boosting will add an aggressive edge to the sound.
- 800Hz – 2kHz: Boosting in this region will bring out the twang in your sound. Cutting will create a rounder, less aggressive tone.
- Above 3kHz: Boosting in this region can add brightness and sheen. Cutting in this region can minimize noise and reduce harshness.
Controls at a Glance
Bass Guitar
- 30Hz – 80Hz: The sub-bass region. Be careful when boosting in this range; your speakers might not be happy if you boost too much.
- 80Hz – 150Hz: The bass region. Boost and cut in this region to change the amount of bass in your sound.
- 150Hz – 500Hz: If your bass sounds too muddy, try cutting in this region. If it needs a little warmth, try boosting in this region.
- 500Hz – 900Hz: Boosting in this region can add mid-range growl to your tone. Cutting in this region can make things clean and pristine.
- 900Hz – 3kHz: Boosting in this region can bring out attack. Cutting in this region can help create a rounder tone.
- Above 3kHz: Cutting can bring down the noise without much effect on the signal.
Boosting can add a sense of air and space.
DI’d Acoustic Guitar
- 35Hz – 100Hz: Cutting in this region can help reduce rumble.
- 100Hz – 200Hz: This range is primarily responsible for the boominess of your acoustic guitar. Cutting or boosting here can help with low end projection.
- 400Hz – 500Hz: Boosting in this range can bring out warmth. Cutting in this range can help remove mud in your sound.
- 500Hz – 4kHz: This broad slice of the sonic spectrum is where most of your acoustic signal lives. Boosting here will make your guitar sound more aggressive, while cutting will help mellow it out.
- 4kHz – 8kHz: The brightness of your acoustic lives in this region. If your instrument sounds like you’re hearing it through a wall, boost in this range. Cutting in this range will remove harshness.
- 5kHz and Above: Boosting in this range will bring out air in your sound, and cutting will reduce noise. Beware of feedback though!
Quick start
Sitting in the Mix
Low cut to leave room for bass and drums in the mix. Mid boost at the
guitar’s sweet spot. Cutting those pesky shrill high frequencies.
Distortion Tamer
To tame high gain distortion, cut some of the lows and boost what’s left.
Boost to the mids and cut any
shrill harmonics for a more even frequency response.
Country Humbucker Twang
Boosting the high mids and really pushing that high shelf filter to get
that twang. Cutting the lows and highs slightly to sit better in the mix.
Airy Acoustic
Cuts extreme highs and lows while boosting what’s left of the lows. Nice mid
boost and selective high removal means it still sounds natural. but lighter.
Buttery Bass
Cuts out highs and high mids while maintaining low end and enough mids to
still bite. The result is smooth and consistently buttery.
Doom Bass
Heavily boosted low to create a sub bass and boosted mids to accent high mid
response, which creates tight lows and fuzzy sustain.
Gnarly Bass Synth
Tames the piercing frequencies from the cranked resonant filter so it sounds
less sharp. Bass boost really fattens up the low end.
Underwater Black and White
Extreme filtering with selective narrow band frequency boosts to make your
instrument sound underwater, flickering in the light of an old projector.
