Are you someone that’s always striving to enhance your tone? It’s time to un-leash the power of the Empress ParaEQ w/Boost EQ Pedal on your instrument – sadly, it may piss you off that you haven’t been using it for years.

Most Beta testers were not excited to test this pedal for us – it didn’t have the bells and whistles of the superdelay…but they were pleasantly surprised. Here are a few comments:

I'm beginning to dislike my clean tone without this pedal on.
- Ian, electric guitar player.

Wow, the eq is the best I’ve heard in a pedal. It out-performs my _______ eq and I’m able to get a huge variety of tones. I also love that it’s so small
– Jake, upright bass player and recording engineer.

What's been really nice about this pedal is how fast I can get to really nice sounds with it. I wasn't expecting that. I was expecting to have to hunt for a while. That's been my experience with DAW-based para eq plugins. Not so with the pedal. It's very quick to sweep and find a sweet frequency spot, both cutting and boosting.
– Peter, guitar player.

Design Philosophy

The Empress ParaEq w/Boost EQ Pedal is designed to be a simple device that does its job extremely well. We noticed that the EQ section of many instrument amplifiers offer a very limited range of control. We designed the Empress ParaEq w/Boost to give musicians a powerful, musical, high quality EQ in a conveniently small package. The signal path of the ParaEq w/Boost is comprised of the highest quality components chosen for their transparency, powerful tone shaping capabilities, and low operating noise. With the Empress ParaEq w/Boost your instrument will still sound like your instrument, only better.

Features & Specifications

  • Ultra Transparent Sweet Sounding EQ – enhance your sound without masking the tone of your instrument.
  • Lots of Control - with switchable q, fully over-lapping sweepable frequency selection, and 15dB of cut and boost you’ll get all the control you need.
  • Ultra-Quiet – You’ve come to expect our pedals to be noise free and we’ve delivered once again. If you put this at the front of your chain and boost a bit you’ll also cut down on the noise your other pedals are introducing.
  • Loads of Headroom - Internally switchable to run off 9/12/18V power supplies.
  • 30dB of Boost - making it an ideal candidate before long effects chains and overdriving tube amps.
  • Pristine Clean Sound – We measured the distortion to be less than 0.03%. Pretty remarkable for a guitar pedal.
  • True Bypass - The Empress ParaEq w/Boost EQ Pedal employs true bypass, so you can be sure that it's not affecting the signal when disengaged.
  • Perfect Size - The enclosure measures approximately 4.5" by 3.5" by 1.5", which is delightfully small when considering all the features packed into this unit.

Question: What kind of bypassing does the ParaEq have?

Answer: The Paraeq has true bypass switching. Older Paraeqs use the blue bypass switch. Newer Paraeqs use a relay to switch.

Question: What are some applications of the Empress ParaEq?

General Sweetening - Say you really like the tone of your guitar but find it could just be a little brighter and detailed. With the Empress EQ adding a small boost in the range of a of 3kHz to 5kHz with a broad Q can add a bit more detail while still retaining the sound of your instrument. Similarly, adding to the lows would bring out some warmth.

Tone Correction - Say you've set your amp up in the venue and find that the acoustics of the stage are making your rig sound too 'boomy' or 'boxy'. By cutting some of the frequencies in the lower mids (200Hz- 600Hz) with a medium Q you can bring minimize the negative effect caused by the room acoustics. Also, if you find your guitar isn't cutting through the rest of the band you can boost in the upper mids instead of just turning up the volume, which could lead to you drowning everyone else out.

Feedback Stopper - With Di'd acoustic instruments playing live can sometimes be a nightmare because of the feedback coming through the monitors. Using the Empress Mid and Hi controls in the 'tight' Q setting you'll be able to cut at the frequencies causing the feedback while retaining much of your instruments tone. With most equalizers the Q is not very tight, so by cutting higher frequencies your instrument gets much duller and 'muddy' sounding.

Distortion Enhancement - Having eq control before the amp can shape distortion sounds. For instance, if you want the treble of your signal to distort more you can boost it before the amp. The boost control on the EE Eq is also great at overdriving the input of tube amps in a very musical way.

The Empress ParaEQ has three 'bell shaped' bands of eq : low, mid and high. Each band has the following three controls:

Low/Mid/Hi Frequency - This control selects the frequency at which you'd like to boost or cut. For flexibility, the frequency controls span a wide range. This makes the eq good for bass players who want to adjust the low frequency part of the signal and for acoustic guitar players who may want to remove a high frequency that is prone to feedback while playing live.

Q - The Q determines the range of frequencies which the eq affects. i.e. If you have a wide Q and you're boosting than the frequencies around the frequency selected will get boosted as well. Conversely, if you select a tight Q and are boosting you'll tend to only boost at the selected frequency and frequencies close to it, the other frequencies will remain un-touched. When looking at the eq, 'medium q' is the left switch position, 'tight q' the middle, and 'wide q' on the right.

Lo/Mid/Hi Gain - This determines the amount of boost or cut. At 12 o'clock there is no boost or cut. At the extremes the unit will provide 15dB of boost or cut.

Boost - This is an output boost control. It is perfect for providing gain before an effects chain to minimize noise, or to overdrive the input of a tube amp. The range goes from 0dB to 30dB.

Input pad - This control lowers the level at the input of the eq. Ideally, this control should be set at 0dB to maximize the signal to noise ratio of the unit. However, if you are adding lots of gain with one of the gain controls you may be clipping the eq internally - you'll hear distortion when this happens. In this case switch the input pad to -6dB or -12dB. By lowering the level at the input you'll prevent the distortion.

Bypass - This is a true bypass switch, which does exactly what its name implies.

Question: What are the ranges of each band of EQ?

Answer: Low Frequency - 35Hz to 500Hz
Mid Frequency - 250 Hz to 5kHz
High Frequency - 1kHz to 20 kHz

Question: How Much Gain does each band offer?

Answer: Each band of EQ has -15dB to +15dB available

Question: What is the range of the boost knob?

Answer: The boost ranges from 0dB to +30dB (That's a lot of boost!!!)

Question: What Q's are available?

Answer: Each band has 3 Q settings: Narrow, Medium and Wide. For the low band, the Qs are around 1.2, 2.6, and 8. For the mid band, the Qs are around 1.0, 2.3, and 3.9. For the high band, the Qs are around 1.0, 2.4, and 3.9.

Question: Ummm... the manual gives different numbers for the Qs. What?

Answer: Sorry, the manual is wrong. We'll fix it in the next printing.

Question: What the hell is Q?

Answer: This guy. Also, it's the width of the eq relative to it's center frequency.

Question: What input pads are available?

Answer: The input pad is selectable between 0dB, -6dB and -12dB.

Question: Is the ParaEQ true bypass?

Answer: YES!

Question: What power supply does the ParaEQ need?

Answer: The power supply must be 9v DC, negative tip. We recommend the Boss PSA-120 adaptor.

Question: Does the ParaEQ come with a power adaptor?

Answer: Nope, but unless this is your first pedal, you probably already have one that will work. As long as it's 9v DC, negative tip... you're good to go.

Question: Can the ParaEQ work from batteries?

Answer: Nope.

Question: Will the ParaEQ work with the BBE Supa-Charger?

Answer: Yes

Question: Will the ParaEQ work with the Voodoo Labs Pedal Power and Pedal Power II?

Answer: Yes

Question: What is the input and output impedance of the ParaEQ?

Answer: The input impedance is 340 Kohms and the output impedance is 510 ohms.

Question: When I hit the bypass switch, it makes a really distorted sound, or a really huge click. What's wrong?

Answer: If you take the lid off the back of your pedal, you'll see that the bypass switch is one of two types. Here's some pictures to help you identify.

Blue (or greenish) bypass
Relay bypass

If you have a blue (or greenish) bypass switch, the problem is probably that it has broke. We can replace it for you. Cody can help you with that, please email him at

Question: Even when I'm bypassing the pedal, it seems like there's a volume drop and/or tone loss. What's going on?

Answer: See the above answer. Contact Cody at and he'll help you out.

Question: I play bass! Can I rock out through this pedal?

Answer: Yes! All of our pedals play nicely with bass. Check out the "Features & Specs" section for information on the frequency response of our pedals. We have lots of customers who play bass through our pedals!

Question: Can you mod my pedal so that an expression pedal jack controls one of the knobs?

Answer: No, sorry. But it's not a hard mod to do. Here's a good resource on how to do it: Add an Expression Pedal to Any Effect. If you don't want to do it, you the fine folks at Nice Rack Canada do. Send them an email at

Question: The pots turn easily, so they move when I accidently hit them during a show. What can I do?

Answer: One of our customers has a great solution to this problem. If you wrap rubber bands at the base of the pot it makes it harder to turn.
