Dunlop GCB95

Dunlop GCB95

The Dunlop GCB95 is a Cry Baby wah pedal. It has a basic design with a diecast construction. It’s very hefty, weighing 3.7 lbs, but it can certainly take some hard usage and offer years of dependability.

The 100k Ohms Hot Potz potentiometer will let you create the quick, sharp wah sound effect. By moving your foot back and forth on the pedal, you can alter the wah effect. You will get some more treble, and by releasing it, you will achieve some more bass.

In terms of tone, the GCB95 delivers the original Cry Baby tone, making it one of the most suitable pedals for recreating Jimi Hendrix’s sound. The Cry Baby GCB95 is also related to some of the other legendary rock musicians, like Buddy Guy, David Gilmour, so it also works great for covering their songs or producing similar sound.

Note that you won’t get the adjustable sweep or boosts with this pedal: it’s quite minimalist since it doesn’t provide any control knobs. It only has an input and output, and a socket for the power adapter.

However, the GCB95’s ensures quite an aggressive sweep which makes it one of the best wah pedals for cutting through distortion. Since the GCB95 is not a true bypass pedal and provides no adjustability, its voicing is actually subject to the personal taste.

The pedal has 10 x 4 x 2-1/2 inches in size. It can be powered by the Dunlop ECB-03 AC adapter or the Dunlop DCB10 DC Brick power supply. It also allows for a stand-alone operation via the 9V battery.


  • The pedal has easy battery access.
  • The GCB95 is quite versatile in terms of applications: from the usage with a clean guitar solo to the usage with the distortion.
  • It works great for most music genres.


  • It doesn’t have the on/off switch, so it turns on and creates a sound every time you make a full step.
  • The pedal is a bit noisy.

Dunlop CBM95

Dunlop CBM95

In the case if you don’t consider the wah-wah effect as one of the most important ones for your music, or just don’t want a bulky and heavy pedal, this model from Dunlop can be just what you need. It’s a mini wah pedal which is only 5.2 x 3 x 2.6 inches in size and will easily fit in a small pedalboard or a gig bag pocket since it’s half the size of a standard wah pedal. This pedal is made of metal (just like the full-sized Dunlop’s pedals) to provide increased durability but still weighs slightly more than 1 lb.

Buyer’s Guide

How The Wah Pedal Can Change The Sound?

When it comes to how wah pedals alter the sound, one of the most important aspects seems to be the technology employed in the pedal’s manufacture. In fact, different brands use different technologies. Some of them use digital hardware with the purpose to create a more modern sound. The others, especially the older brands, rely on an old-school sounding, like Cry Baby and VOX, for example. There are also some brands that combine both new and old technologies to create innovative sounding.

Generally, the wah pedal gives you the possibility to experiment with your guitar’s sounding. When you press the pedal with your foot, you create the effect of 3D sound. When you release the pedal, this effect weakens. This way, by pressing and releasing the pedal, you can hear the “wah-wah” sound. The rhythm you use to press the pedal affects the overall rhythm of the performed melody. The electric guitar effects pedal also helps change the guitar sound from bassy to trebly as you move your foot from up to down.

The wah pedals are also used for rhythmic sweep (like Eric Clapton’s solo from White Room, Dream, and all of his funk songs) or for slow movement around the frequency center (Jimi Hendrickson’s Voodoo Child).

Nevertheless, there are at least two reasons for an unsatisfactory sound when using this type of pedal: when you use the wah-wah pedal of bad quality (a good pedal should sound good throughout the range) or when it’s located in the wrong place in the signal chain.

However, any wah-wah pedal does affect the tone of your guitar, and it doesn’t matter either this pedal is good or not. By comparing the characteristics of several pedals, you will be able to decide which one of them will affect the way your guitar sounds in the right way.

What is a sweet spot?

A sweet spot is a kind of sound you are able to reach between two sharp extremes: from very bassy to very muddy and from very trebly to very harsh. It’s one of the most essential things that you should consider when you are opting for the best wah-wah pedal. Obviously, your choice, just like the choice of any musician, should be based on your music style and should meet your personal preferences. Make sure the pedal is adjustable enough to reach your sweet spot before purchasing it.

What is the best place for this pedal?

The wah-wah pedal is one of those pedals that change the sound in a quite significant way. This way, it’s traditionally placed at the beginning of a signal chain: right after compressors but before shifting and volume guitar pedals.

If you are afraid of getting a nasally sound, put the pedal before the distortion/overdrive pedal. Being placed after the wah pedal, the distortion/overdrive pedal will emphasize the mid frequencies without changing the nature of their sound.

However, you are always open to experiment. Let’s not forget about legendary Jimi Hendrix that used the wah pedal in numerous different potions (like placing it before the booster pedals) and his music only benefited from this.

Few tips and tricks for using

There are a lot of techniques on how to use a wah pedal. You can slowly press and release it while playing a fast solo. You can also do a popular in the 70s “waka-waka” sound when jamming the strings with your left hand and playing with the right hand while pressing the pedal in the same rhythm. Or you can use the pedal as a soft modulation effect or as a filter, leaving it in a fixed position.

In fact, the wah-wah pedal is most frequently used to accentuate a certain note: you can do it by controlling how strong both the signal and the sound can be changed. It’s possible to accent even a whole riff by gradually pushing the pedal with your foot. You can also get a fading effect if you mute the pedal out while the riff/note is in a full swing.

The sweeping speed is also important. It’s different for each song: split the tempo in accordance with the time signature (just switch between tapping and pulling as you count).

By quickly pressing up and down on the pedal, you can get the most recognizable fuzzy “wah-wah” effect.

Most wah pedals also come with a variety of control knobs which allow for different settings. Let’s take a closer look at some of the most popular controls:

  • Treble/Bass control adjusts the sounding (decibel rate) of low and mid frequencies.
  • Bias allows creating a warmer and more bassy sound (therefore, the wah-wah will be more pronounced) as you tweak it up.
  • Volume. Most of the optical pedals go equipped with the volume knob to boost the volume level.
  • Decay can be adjusted in accordance with the time during which the wah-wah sound effect changes frequencies. The lower the level of the decay, the higher the interval between the sound alterations.
