Dunlop 105Q Cry Baby Bass Wah Pedal Review: The Definitive Solution for Low-End Groove

For years, bass players have lived in the shadow of guitarists when it came to expressive effects. We have all been there: you pick up a standard wah pedal, plug it into your rig, and the moment you engage the effect, your low-end presence vanishes into thin air. You are left with a thin, nasal “quack” that might cut through the mix but completely destroys the foundation of the song. This struggle—the battle between having a cool filter effect and maintaining the “thump” that defines our role—is exactly why many bassists avoid wah pedals altogether. However, failing to find a solution means missing out on the legendary funk and rock tones used by icons like Flea or Bootsy Collins. This is where the Dunlop 105Q Cry Baby Bass Wah Pedal enters the conversation, promising to provide that iconic vocal sweep without sacrificing a single hertz of your precious bass response.

In our extensive testing, we found that the Dunlop 105Q Cry Baby Bass Wah Pedal isn’t just a repurposed guitar pedal; it is a ground-up redesign of the wah circuit specifically for the frequency range of the bass guitar. If you have ever felt your heart sink as your bass tone turned into a tinny mess during a solo, you know why finding the right gear is crucial. We spent weeks putting this pedal through its paces in rehearsal rooms and live settings to see if it truly lives up to the “Cry Baby” legacy while catering to the unique needs of the modern bassist.

What to Consider Before Buying Electric Guitar Wah & Filter Effects for Bass

An Electric Guitar Wah & Filter Effects unit is more than just an item; it’s a key solution for adding rhythmic movement and vocal-like expression to your playing. For a bassist, these effects allow you to move beyond simple time-keeping and into the realm of melodic lead lines and percussive, funky textures. By manipulating the frequency peak of your signal, a wah pedal lets you “speak” through your instrument, creating a dynamic interaction that responds directly to your physical movement.

The ideal customer for this type of product is someone facing a stale tone or looking to replicate classic funk, psychedelic rock, or modern fusion sounds. It is perfect for the bassist who wants to stand out during a solo or add a “bubbling” texture to a synth-bass line. Conversely, it might not be suitable for those who play strictly traditional jazz or bluegrass where a transparent, unaffected tone is paramount. If you are a “set it and forget it” player who never strays from a clean DI sound, a manual wah might be more of a distraction than a tool. In those cases, a dedicated compressor or a high-quality preamp might be a better investment.

Before investing, consider these crucial points in detail:

• Dimensions & Space: Wah pedals are notoriously large and heavy because they require a physical treadle for your foot. You need to ensure your pedalboard has enough real estate (typically about 10 inches in length) and that your power supply can handle the 9V requirement. We found that the Dunlop 105Q Cry Baby Bass Wah Pedal fits standard boards well, but its weight is significant enough to require heavy-duty Velcro.
• Capacity/Performance (Frequency Sweep): Not all wahs are created equal. You must look for a pedal specifically voiced for bass. A standard guitar wah sweeps through high-mids and highs, which sounds “ice-picky” on a bass. The performance of a bass wah is measured by how well it maintains the fundamental low frequency while moving the filter peak.
• Materials & Durability: Since you are literally stepping on this device with your full weight, plastic housings simply won’t cut it. Look for die-cast metal construction. The longevity of the internal “pot” (potentiometer) is also vital; cheaper pedals develop “scratchy” noises over time, whereas high-end models like the Dunlop use road-tested components designed for thousands of hours of use.
• Ease of Use & Maintenance: Consider whether you prefer a “switchless” design or a traditional “click-on” toe switch. Switchless designs, like the one found on the 105Q, engage as soon as you touch the pedal, which can be a lifesaver in a fast-paced live environment. Maintenance usually involves keeping the gears clean and occasionally checking the tension of the treadle.

While the Dunlop 105Q Cry Baby Bass Wah Pedal is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

First Impressions and Key Features of the Dunlop 105Q Cry Baby Bass Wah Pedal

When we first pulled the Dunlop 105Q Cry Baby Bass Wah Pedal out of the box, the first thing that struck us was the stark white finish. Most Cry Baby pedals are iconic black, but this white chassis immediately signals that this is a different beast entirely. It feels incredibly substantial in the hand—weighing in at about a pound, it has that classic “tank-like” build quality that Jim Dunlop is famous for. You can see its full feature set and user reviews to get a sense of how consistent this build quality is across the board.

Unlike traditional guitar wahs, there is no “click” switch under the toe. Instead, the 105Q features an auto-return spring. As soon as you step on it, the effect is active; as soon as you take your foot off, it springs back to the heel position and bypasses the effect. This is a game-changer for bassists who need to jump in and out of the groove quickly. On the side of the pedal, you’ll find two small but sturdy knobs: Volume and Q. These allow you to boost the signal to compensate for any perceived volume loss and adjust the intensity (width) of the wah effect. It is a level of customization that we found to be far superior to the “one-size-fits-all” approach of vintage reissue pedals.

A Deep Dive into the Performance of the Dunlop 105Q Cry Baby Bass Wah Pedal

The “Bass-First” Circuitry and Frequency Preservation

In our tests, the most impressive aspect of the Dunlop 105Q Cry Baby Bass Wah Pedal was undoubtedly its frequency response. Most wah pedals work by applying a band-pass filter that moves up and down the frequency spectrum. On a standard guitar wah, this filter often cuts off everything below 300Hz-400Hz. For a bass player, that’s where the “meat” of the instrument lives. When we engaged the 105Q, we noticed that the low-end remained remarkably consistent. This is due to the proprietary potentiometer and EQ circuitry that allows the clean low frequencies to pass through while only applying the wah effect to the mid and high overtones.

When we played a heavy funk line in the key of E, the low E string still shook the room even as we rocked the pedal forward for a sharp, aggressive “wah” sound. This “dry-path” preservation is what separates a professional tool from a toy. We found that even when using high-gain distortion before the wah, the Dunlop 105Q Cry Baby Bass Wah Pedal didn’t turn the signal into a muddy mess. It maintained clarity and punch, making it a feature that really sets it apart from its competitors. If you’ve ever been frustrated by losing your place in the mix the moment you step on your wah, this pedal provides the technical solution you’ve been looking for.

Mastering the Auto-Return and Switchless Operation

If you have ever played a live show, you know that timing is everything. Trying to click a mechanical switch under the toe of a wah pedal exactly on the “1” of a measure while also keeping a complicated rhythm can be a nightmare. The Dunlop 105Q Cry Baby Bass Wah Pedal solves this with its spring-loaded auto-return mechanism. During our evaluation, we found this to be incredibly intuitive. As soon as your foot applies pressure, the effect is live. There is a very slight, adjustable delay for when the effect turns off (to prevent accidental cutting if you are rocking slowly), which we found to be perfectly calibrated out of the box.

This design encourages a more percussive style of playing. We were able to “stab” at certain notes with the wah effect and immediately return to a clean sound for the next bar. It feels more like an extension of your foot than an external device. We also noted that the tension of the spring is “just right”—it’s firm enough to give you control over the sweep but not so stiff that it causes foot fatigue during a long set. For any bassist who values fluidity and seamless transitions, the auto-return feature is a massive win. You can check the latest price and availability to see how this innovation fits into your budget.

Fine-Tuning the Sound with Volume and Q Controls

The addition of the Volume and Q controls on the side of the Dunlop 105Q Cry Baby Bass Wah Pedal elevates it from a simple stompbox to a versatile tone-shaping tool. The “Q” control is particularly vital; it adjusts the frequency breadth of the effect. When we cranked the Q knob, the wah became incredibly sharp and vocal—perfect for aggressive rock solos. When we backed it off, the effect became more subtle and “liquid,” ideal for under-the-radar funk grooves. One user review mentioned that they “crank the Q” to love life, and after our testing, we have to agree—the range of expression available here is staggering.

The Volume control is equally important. Many wah pedals suffer from a perceived drop in volume when engaged because the filter narrows the frequency band. With the 105Q, we were able to dial in a slight boost (up to +15dB). This meant that whenever the wah was engaged, the bass actually stepped forward in the mix, ensuring that our solos were heard loud and clear. Having this control directly on the pedal meant we didn’t have to rely on a separate boost pedal or the sound engineer to fix our levels. It’s these thoughtful touches that make us recommend that you see its full feature set and user reviews before making a final decision.

Tour-Ready Build and “Made in the U.S.A.” Reliability

Lastly, we have to talk about the durability. The Dunlop 105Q Cry Baby Bass Wah Pedal is built like a tank in Benicia, California. We took it on a short run of club dates and it handled the abuse of travel and beer-soaked stages without a flinch. The rubber treadle on top provides excellent grip, even if your shoes are wet, and the jacks are high-quality 1/4-inch components that won’t wiggle loose. We’ve used many pedals over the years that felt “plastic-y” or fragile, but the 105Q gives you the confidence that it will work every single time you step on it.

Internally, the wiring is clean and the component quality is top-tier. While it can be powered by a 9V battery, we highly recommend using a dedicated 9V DC power supply for consistent performance, especially since the “Volume” boost requires steady voltage to maintain its headroom. For the professional bassist who cannot afford a gear failure in the middle of a tour, the reliability of the Dunlop 105Q Cry Baby Bass Wah Pedal is its own reward. It is a piece of gear that feels like it will last a lifetime, which is a rare find in today’s market. You can view more details and pricing here to see why it remains a staple on professional pedalboards worldwide.

What Other Users Are Saying

The general sentiment surrounding the Dunlop 105Q Cry Baby Bass Wah Pedal is overwhelmingly positive, especially regarding its “plug-and-play” nature. As one user noted, the pedal offers a “superb feel and sound,” emphasizing that rocking the pedal forward and matching the volume knob to your specific bass is the secret to success. This aligns perfectly with our findings: the pedal is highly interactive with your instrument’s output level. Another user highlighted the “amazing range” when the Q control is cranked, stating it changed their entire approach to soloing.

On the flip side, some users have mentioned that the white color, while striking, is a “magnet for scuffs.” If you are someone who meticulously cleans your gear, this might be a minor annoyance. A few reviewers also noted that the “auto-off” delay, while adjustable internally, can take a minute to get used to if you are coming from a traditional click-style wah. However, these are minor gripes compared to the praise for its low-end retention. Overall, the consensus is that for the price and build quality, it is the benchmark for bass-specific wah pedals available online today.

Comparing the Dunlop 105Q Cry Baby Bass Wah Pedal to Top Alternatives

While we believe the 105Q is a top-tier choice, it’s important to see how it compares to other popular options to ensure you’re getting exactly what your style requires.

1. Dunlop 535Q Multi-Wah Guitar Pedal Adjustable Boost

The Dunlop 535Q is often considered the “Swiss Army Knife” of wah pedals. While it is technically marketed as a guitar pedal, its six selectable wah ranges and adjustable boost make it surprisingly versatile. Compared to the Dunlop 105Q Cry Baby Bass Wah Pedal, the 535Q offers more tonal variety but lacks the specific frequency-split circuitry that preserves the bass fundamental as effectively. If you play both guitar and bass and only want to buy one pedal, the 535Q is a strong contender. However, for a dedicated bassist, the 105Q’s auto-return and bass-voiced pot provide a much smoother, “thumpier” experience.

2. VOX V847-A Classic Wah Guitar Effects Pedal

The VOX V847-A is the gold standard for that vintage, 1960s British wah sound. It is a simple, no-frills pedal with a very “vocal” sweep. When compared to the 105Q, the VOX is much more “lo-fi.” It does not have a volume boost or a Q control, and it definitely sucks out some low-end when used with a bass. We would recommend the VOX only for bassists who want a very specific, thin, psychedelic 60s sound for recording. For modern live performance where you need to keep the groove heavy, the Dunlop 105Q Cry Baby Bass Wah Pedal is a far superior choice.

3. Donner Mini Auto Wah Guitar Pedal

The Donner Mini is an “auto-wah” or envelope filter, meaning you don’t use your foot to rock a treadle; the effect responds to how hard you pick the strings. It is significantly smaller and cheaper than the Dunlop 105Q Cry Baby Bass Wah Pedal. While it’s great for saving space, it lacks the physical expression and control of a manual wah. We found that while the Donner is fun for “bubbly” funk sounds, it doesn’t give you the “growl” and sweep control that the 105Q provides. It’s a great entry-level budget option, but it isn’t in the same professional league as the Dunlop.

The Final Verdict: Is the Dunlop 105Q Cry Baby Bass Wah Pedal Worth It?

After weeks of testing and comparing it against the best in the industry, our conclusion is clear: the Dunlop 105Q Cry Baby Bass Wah Pedal is the gold standard for bassists who refuse to compromise on their low-end. Its combination of frequency-specific circuitry, switchless auto-return functionality, and robust build quality makes it an essential tool for any serious player. Whether you are playing fingerstyle funk, pick-heavy rock, or experimental fusion, this pedal provides the expressive power you need without the tone-sucking drawbacks of cheaper alternatives.

We highly recommend the 105Q for its reliability and professional feature set. It solves the biggest problem bassists face with wah pedals—loss of foundation—and adds convenient features like the Volume boost to ensure your solos actually cut through the band. If you are ready to take your bass playing to the next level of expression, you should check the latest price on the Dunlop 105Q Cry Baby Bass Wah Pedal and add this legendary piece of gear to your rig today. You won’t regret the investment in your tone and your groove.
