The Dunlop MC-404 CAE Wah Pedal has two knobs. One turns on the MXR circuitry, the other shifts the wah-tone. Choose between "Yellow Fasel," a deep tone, or "Red Fasel," for the classic cry baby tone. This pedal has ideal applications for the stage, featuring kick-switches on either side for hands-free adjustment and an LED light to show you the pedal is live and kicking. Bob Bradshaw of Custom Audio Electronics designed the MXR MC-404 CAE Dual Inductor Wah Pedal with the Cry Baby design team to create a highly versatile wah-wah with top-grade components. The MC404 CAE Wah features dual Fasel inductors with 2 distinct voices (high-end emphasis or low-to-mid resonance), and a built-in MXR MC-401 Boost/LineDriver that adds even more flexibility. Choose between inductors and turn the boost on or off with the side-mounted kickswitches. Bright LEDs on each side of the wah indicate operation status. The MC404 CAE Wah boasts true hardwire bypass, a long-life CTS potentiometer, and internal pots for the Q control-which varies the intensity of the wah effect-and gain adjustments. You get the high performance and quality that you expect from Dunlop, the world leader in wah-wah technology. Bob Bradshaw has been one of the world's foremost designers of custom guitar pedal boards and effects systems for many of rock's most influential guitarists for 3 decades. And for just as long, MXR and Cry Baby have been synonymous with the effects pedal innovations that have shaped the tone of modern electric guitar playing. So it was only natural for them all to join forces to create a dynamic line of pedals offering the ultimate in tone, functionality and road-worthy dependability. Since 1980, CAE's groundbreaking pedal designs were made in limited quantities only for a select clientele of world-class guitarists. But now these very same devices and circuits are available to all.

All-around thumbs up!
Size: 934W-Z, Color: Black
So far, so awesome. Easy to assemble, comfortable, arrived quickly and is exactly what I was looking for. I have a tall work bench in my new studio so I needed a chair that we could allow me to sit higher than a regular office chair and allow me to get off my feet after standing on the concrete floor. Plus its a nice looking chair that I am sure will last a long time. I love the flip-up arms and the lumbar support. This is just right!

Perfect Balance of Comfort, Support, and Style!
Size: 934-Z, Color: Black, Size: 934-Z, Color: Black
I’ve been using this chair for a few weeks now, and I’m genuinely impressed with how much of a difference it’s made in my workspace. The mesh back is one of my favorite features—it offers excellent breathability and prevents that sticky, overheated feeling you sometimes get with solid-back chairs, even after sitting for hours. The seat cushion is firm enough to give proper support but still has enough give to keep me comfortable through long workdays. It feels like the perfect middle ground between soft and supportive. The adjustable foot ring has been a complete game changer for me. I use a taller desk setup, and having somewhere to rest my feet makes a huge difference in posture and overall comfort. Whether I’m sitting upright for focused work or leaning back to read, it’s always at the right height. The flip-up armrests are another smart design choice. When I’m typing, I like to have them down for support, but when I’m done, I can flip them up and push the chair neatly under my desk—saving space and keeping things tidy. The casters roll smoothly on both hardwood and rugs, so I can move around easily without scraping the floor or getting stuck. The overall build quality feels solid and sturdy, with no wobbles or creaks. Assembly was surprisingly quick—everything was clearly labeled, the parts felt durable, and it only took me about 20 minutes from opening the box to sitting in the chair. The sleek, modern look is another big plus—it blends in perfectly with my home office décor without feeling bulky or taking up too much visual space. If you’re looking for a chair that combines comfort, ergonomic support, durability, and style, I can’t recommend this one enough. It’s equally great for work, studying, or just relaxing at your desk, and it’s definitely been worth every penny.

OK for the price, but overall comfort is avergae
Size: 934-Z, Color: Mustard
Easy to put together, color (mustard) accurate to images, and while I understand this is not a high-end chair, I feel like it still needs to be rated for its quality. Pros: the seat cushions are fairly comfortable and it rolls well. Adjustable footrest is easy enough and mostly sturdy. Cons: For a tall office chair, it doesn't go up high enough. I actually had to lower my standing desk to sit at it, which then isn't where I want it when I'm standing now. It's also a bit wobbly. The seat area's attachment to the post isn't as solid as it should be for a tall chair, so while sitting, it does tend to lean/slope forward and wobble side to side. The lumbar support is not adjustable, so I'm not even really sure what it does. And the armrests are not very comfortable to use. Since they are hard plastic, they are just a bit too rigid to rely on for any comfort. They are basically there to hold on to when you're getting out of the chair.

Good Value for a Tall Chair
Size: 934W-Z, Color: White
I have received this chair just today and would like to give my first impressions of it. Height is super adjustable as well as the foot rest. My desk is very tall (~34 inches vs standard ~29 inches) and does not suit a standard height chair. This chair's height is enough to sit comfortably at mybut also still having adjustment to be even higher. Lumbar support is a manual adjustment that can be adjusted by sliding the lumbar piece up or down and it seems it can be tiled as well. No reclining feature or slight backrest tilt adjustment. I'm used to my chairs reclining so it feels a little awkward siting in a flat base and straight backrest. I feel like I'm sitting too forward or leaning forward slightly but is probably something I can get use to. Easy to put together and feels very sturdy. Plastic parts of chair are made from a really sturdy plastic, like playhouse plastic materials. Wheels roll around carpet easily. Mesh seems to be a strong material, though the mesh feels kind itchy on bare skin. Overall, I think this is a good chair to get if you're needing a tall chair for a good value and can sacrifice no backrest tilt.

Excellent value for money!
Size: 934W-Z, Color: Black, Size: 934W-Z, Color: Black
I absolutely love this office chair! I needed a chair that could support my standing desk without sacrificing comfort, and this one completely exceeded my expectations. It's incredibly sturdy and durable, well-made, and the height adjustment is super convenient, making it easy to find the perfect fit. Even during long hours of work, the seat is comfortable, and the ergonomic design effectively reduces pressure on my back and legs. I love its clean, modern look—it fits my home office perfectly. Assembly was quick and easy, and for this price, the quality is absolutely fantastic!
