The Wampler EQuator is an analog equalizer pedal from Wampler. Instead of the row of sliders found on a graphic EQ, it gives you a volume control, fixed bass and treble controls, and two semi-parametric mid controls, and the pedal carries a 723Hz marker for finding a Tube Screamer's signature mid hump1.
Wampler positioned the EQuator as an answer to constant demand from its fans for an EQ pedal, with Delicious Audio admitting the introduction "may be a bit overdue"2. The maker's own framing is that an EQ pedal is one of the most powerful devices you can place in a rig, and that the EQuator trades the learning curve of individual sliders for a simpler, player-friendly layout3.
An analog four-band EQ with two semi-parametric mids
The EQuator is built around an active four-band EQ: bass, treble, and two bands for the midrange, with pre-defined frequencies1. Rather than giving every band its own slider, Wampler fixed the bass and treble bands and made the two mid bands semi-parametric, meaning you choose the center frequency you want to cut or boost and then set the amount31.
For a player, that layout splits the difference between a simple tone stack and a full parametric EQ. The fixed bass and treble controls handle the broad shaping, while the two mid controls let you hunt down the specific frequencies that matter, whether that is carving out mud or pushing an amp into a mid-forward voice431.
One detail aimed squarely at players who stack overdrives: MusicRadar's review noted the pedal can deliver a Tube Screamer's signature mid hump, "easily found by the 723Hz marker on the pedal"5. That marker gives you a quick reference point for one of the most commonly chased mid bumps in guitar tone.
The controls
| Control | What it does |
|---|---|
| Volume | Sets the overall output level, with what MusicRadar called a healthy volume output1 |
| Bass | Fixed low-band cut or boost1 |
| Treble | Fixed high-band cut or boost1 |
| Mid 1 | Semi-parametric mid band: select the frequency, then cut or boost1 |
| Mid 2 | Second semi-parametric mid band, same arrangement1 |
Each of the two mid modes offers controllable frequency with plus or minus 25 dB of cut or boost6. In the Sweetwater demo from the Wampler booth at Winter NAMM 2018, Brian Wampler walked through those two mid modes and the frequency control for each6.
"the mids two different modes you can control the frequencies of each mid and plus or plus or minus 25 DB"
The EQuator's mid section is its main drawing card. You get two semi-parametric mid controls, and the mids offer two different modes: you can control the frequency of each mid and apply plus or minus 25 dB of cut or boost6. A 723Hz marker on the pedal makes it easy to find a Tube Screamer's signature mid hump5.
Power, build, and price
The EQuator runs on 9V DC with a center-negative plug and draws 23.9mA3. Its jacks are top-mounted, which Delicious Audio noted makes pedalboard placement effortless2. The pedal ships with Wampler's limited 5-year warranty2.

Questions
Is the Wampler EQuator analog?
Yes. The EQuator is an analog pedal, built around an active four-band EQ circuit. It runs on 9V DC with a center-negative plug and draws about 23.9mA, so it sits comfortably alongside other analog pedals on a standard power supply.
Is the Wampler EQuator noisy?
No. Delicious Audio's writeup called out its impressively low noise floor, and the pedal was designed to meet Wampler's usual demand for top quality. As with any EQ, large boosts will amplify whatever noise is already in your signal chain, but the pedal itself is quiet.
How much does the Wampler EQuator cost?
At launch in April 2018 the EQuator listed at $199, with some coverage of the release quoting $199.97. It shipped alongside the Wampler Reflection reverb pedal, which carried the same launch price.
Who designed the Wampler EQuator?
The EQuator was designed by Brian Wampler, who founded Wampler Pedals. Delicious Audio credited his attention to detail and commitment to designing player-friendly products, and Brian Wampler himself presented the pedal at the Wampler booth at Winter NAMM 2018.
