Donner Vowel Mini Wah&Volume Pedal Review – Is It Worth Buying?

4.0 rating

With their fantastic effect that makes a guitar almost talk, wah pedals are the main actors of some iconic moments in electric guitar history. From Jimi Hendrix’s famous Voodoo Child to the master Joe Satriani’s Surfing With The Allien, the flavor of the wah-wah pedal in action can be heard and enjoyed. There is no doubt wah-wah effect is one of the most legendary effects that has been used by guitarists who were seeking to express themselves in a super-cool way.

Wah-wah pedals change the tone using the wah’s rocker pedal; bassy sounds are at the heel-down setting, and the treble tones are found at the toe-down. This transition between the two extreme poles creates the iconic talking sound of the guitar. It makes your tone quite exciting and adds excellent versatility to your pedal set-up.

You can also use the wah pedal like Mick Ronson or Michael Schenker, who keep the rocker in one position, often in mid frequencies, to get a desired tone from the pedal. However, you use it wah pedals are utmost fun and create a whole world of new possibilities.

One of the best wah pedals on the market today is undoubtedly the Donner Vowel Mini Wah&Volume pedal. It is one of the smallest wah pedals, which is great as it leaves much free space for other pedals on the pedalboard, contrary to most of the wah pedals on the market. Furthermore, it can be used as a volume pedal or a wah pedal, and its wah pedal response is based on the classic Crybaby wah response. A pretty great deal overall.

Great value for the priceNarrow frequency response curve

Solid and durable stompbox

The Donner Vowel Mini Wah&Volume pedal deserves 4 stars out of 5 with its compact size, solid and durable stompbox, and its amazingly affordable price. The narrow frequency response curve along with the lack of selectable frequency range which is featured in higher-end models are the reasons for the take-off point.


As a quite young musical instrument and accessories brand founded in 2012, Donner provides extraordinarily affordable and high-quality products to musicians worldwide. Although the brand’s specialty is the effect pedals, they also successfully provide musical instruments and accessories to musicians of all levels with a low budget.

The Donner Vowel Mini Wah&Volume pedal is a great stompbox made from hard plastic, which feels pretty lightweight but sturdy and durable at the same time. It is a mini, elegant-looking pedal with a red body and yellow brand logos and letters. The pedal features a tiny footprint which is much shorter than a standard wah pedal or volume pedal. 

One of the most impressive aspects of the pedal is its compact size. It only weighs around 0.55 lbs (250 g), thanks to its plastic casing, and it has measurements of 2.6” (6.5 cm), 2.4” (6.1 cm), 5.85” (14.9 cm), which is pretty small for a wah pedal. This way, you can save space on your pedalboard and create space for other members for your setup.

As this is a wah pedal based on the classic Dunlop Crybaby, there are no knobs on it. The only switch is the footswitch to turn the pedal into a volume pedal or wah pedal. The rest is adjusted with the rocker. The led indicator on top of the rocker clearly shows which mode pedal is currently using. The green light indicates the volume pedal, while the red light shows the wah pedal is currently in use.

It has standard 1/4” Mono Audio Jack input and output along with a 9V DC power jack as the power supply.

What Power Does Donner Vowel Mini Wah&Volume Pedal Require?

As most of the Donner mini pedals, the Donner Vowel Mini Wah&Volume Pedal requires a 9V DC adapter to work. However, the adapter does not come with the pedal, so you will have to buy a 9V DC adapter separately.

Usually, it is challenging to handle the pedal setup in the chaos of cables and adapters if you have many pedals. That is why you might want to check out the Donner DP-1 guitar pedal supply, which successfully powers up to 10 different pedals. This way, you will get out of the chaos of many cables and adapters, which will save you a lot of time and energy. By the way, the power supply supports 9V, 12V, and 18V pedals which is more than enough.

Of course, you will also need a pedalboard to handle your pedals easier. Donner also offers an affordable solution for this case. I recommend you to check out Donner Guitar Pedal Board Case DB-3 Aluminium Pedalboard. With its measurements of  20” (50 cm) x 11.4” (29 cm) x 4” (10 cm), it can manage around 10 pedals and keep your pedal setup organized.

The Donner Vowel Mini Wah&Volume Pedal Sound Quality

Donner Vowel Mini Wah sounds great both as a wah and a volume pedal. It sounds pretty clear and impressive, especially when it pice is taken into account. Of course, the tonal quality of the wah can not be compared to higher-end models around the $200 mark. Still, with the volume pedal integrated Donner Vowel mini is more adaptable and versatile.

The volume pedal does not color the sound, which is a crucial aspect of a volume pedal. The rocker range is more than enough, which is surprising because the footprint is pretty small. The wide range of control from bottom to top is impressive. However, the range between 0% to 20% is reported to be harder to control, which means you will have to get used to the pedal to have better control of it.

The wah sounds pretty impressive with a vintage tone. It is highly responsive and clear. The only letdown with the wah is that it has a narrow frequency response curve compared to other stand-alone units. But this is not a huge deal-breaker, in my opinion.  Another reported issue is that the volume unbalances when switched to the wah mode from the volume mode, but this can be avoided with different pedal setups and adjustments.

You can hear this high-performing wah with your own ears to have a better opinion. The review is excellent as the wah pedal is used with heavily distorted tones as well as crystal clear tones to have a better grasp on the pedal.

Donner Vowel Mini Wah&Volume Pedal Compared To Other Pedals

Donner Vowel Mini Wah&Volume Vs. Donner Viper Expression&Volume

The twin pedal of the Donner Vowel is called Donner Viper, which is a passive volume and expression pedal which works without any power supply. It has the same features as Donner Vowel with slight differences, such as the green stompbox of the Viper.

The viper is a tremendous mini pedal that saves up plenty of space on the pedalboard. Plus, as it is a passive pedal that works without any power supply, it adds no noise to the signal chain. Furthermore, from 0% to 100%, the pedal provides a smooth fade.

You can use the pedal to adjust your volume or adjust the amount of any desired effect like overdrive, delay or reverb level, modulation, etc. The Donner Viper costs slightly lower than Doner Vowel.

Donner Vowel Mini Wah&Volume Vs. Jim Dunlop Cry Baby Mini 535Q Wah

Jim Dunlop Cry Baby Mini 535Q Wah is a fantastic mini wah pedal with almost the same features as its big brother classic Cry Baby. With its compact size, great wah effect, high sound quality, and sturdy stompbox, it is one of the best mini wah pedals on the market.

When compared to Donner Vowel, Cry Baby Mini takes more space on the pedalboard with its 3,5” (8.9 cm) x 3.5” (8.9 cm) x 6” (15.2 cm) measurements. Also, Cry Baby mini weighs 1.12 lbs (500 gr), almost double Donner Vowel’s weight. Cry Baby can work with battery power, while Donner Vowel can be powered only with adapters.

When it comes to the sound quality and adjustments, Cry Baby mini outruns Donner Vowel. It offers four selectable frequency ranges giving users some leeway in adjusting the pedal as they like. Plus, with the Q knob, users can set the width of the bandpass to emphasize higher or lower harmonics. Furthermore, it features an option to boost up the pedal up to 16dB.

All these features with a classic throaty Cry Baby quality wah effect make this pedal a fantastic choice for guitarists looking for a professional yet mini-sized wah pedal. Donner Vowel is also based on Cry Baby, but it does not offer these wah pedal adjustments. However, it offers a volume pedal that lets you get rid of your volume pedal to save more space. Also, it must be said that Cry Baby mini has a slightly better-sounding wah effect with more balanced frequencies.

Of course, the quality and versatility come with a cost Jim Dunlop Cry Baby Mini 535Q Wah has triple the price of Donner Vowel.

Donner Vowel Mini Wah&Volume Vs. Boss PW-3 Wah Pedal

Boss PW-3 is yet another mini wah pedal that shines with its versatility thanks to its two different modes of wah effects. It is a great sounding pedal with a durable die-cast stompbox and a modern black look.

Boss PW-3 is slightly bigger than the Donner Vowel with its measurements of 3.1” (8 cm) x 7.6” (19.2 cm) x 2.3″ (5.8 cm) and is significantly higher with a weight of 1.8 lbs (800 gr). PW-3 can function with battery power while Donner Vowel can not.

The vintage mode of PW-3 sounds like the iconic 70’s wah sounds like Jimi Hendrix’s Voodoo Child or the Shaftland theme. The pedal clears the bottom end out of your tone when it is wide open to reach that old-school squawk. The other mode is called the Rich mode, which provides a more modern-sounding wah effect. It beefs up the wah’s tone over its entire sweep, which sounds terrific with high-gain tones. 

The wah effect versatility and quality of PW-3 are relatively higher than the Donner Vowel. Of course, the volume pedal option the Vowel has is not provided by PW-3.

As a higher-end wah pedal, Boss PW-3 has a price almost triple the Donner Vowel has.

Donner Vowel Mini Wah&Volume Pedal Is Perfect For Whom?

As a compact and affordable pedal, Donner Vowel Mini Wah&Volume pedal is an excellent choice for guitarists looking for a decent wah or volume pedal to add to their setup without breaking the bank. With two crucial pedals just in one stompbox and its compact size, along with its high sound quality, this pedal can be a fantastic element of any pedal setup.

The pedal performs well in home practice as well as in live performances. So, do not hesitate to use it anywhere anytime. Of course, the pedal’s performance will heavily depend on your amp and pedal setup, as that is the case with any musical accessory. It is reported that with some amps, the volume balance between wah and volume modes can differ. So, try the pedal before buying it if you have the option.

The wah pedal sounds pretty good with any style, from crystal clear tones to heavily distorted metal tones. On the other hand, this pedal is also excellent for guitarists with crowded pedal setups, as the mini size lets you save big spaces on the pedalboard.

The only players who would not enjoy this pedal would be the professional players who are seeking after the higher-end wah pedal effects, which balance the higher and lower frequencies better than Donner Vowel. The narrow frequency response can be a problem for professional regular performer guitarists.

Where To Place Donner Vowel Mini Wah&Volume Pedal On The Pedal Board?

There is a rule of order for the signal chain on pedalboards, and you better follow this rule if you are not seriously experienced with effect pedal setups. In order to use the full potential of all the pedals and avoid them messing with each other’s tones, the signal chain rule should be followed.

The first members of the signal chain are the compressors, volume pedals, filters, wah pedals, and pitch shifters. Later comes the overdrive and distortion pedals, followed by the modulation effects like chorus, phasers, flangers. Finally, the last ones on the signal chain should be time-based effects such as reverb and delays.

As clearly seen on the signal chain order, the wah and volume pedals are located as the first step on the fretboard and signal chain. The instrument’s signal should travel first to these pedals before getting affected by other pedals on the setup. So Donner Vowel should be one of the first pedals on the signal chain.
