Construction Quality

Build Quality Rating: ★★★★
These pedals exhibit the robust construction quality that Keeley is known for, featuring meticulous internal wiring. The compact enclosure is similar in size to a BOSS pedal or other boutique models.
It’s refreshing to see such attention to detail in the aesthetics and functionality of a pedal at this price point.
The Suns includes a playful LED indicator that lights up when the pedal is clipping. While it doesn’t alter the sound, it enhances the pedal’s overall vibe. The other two pedals focus on delivering quality sound without unnecessary embellishments.
the design is sleek and elegant, opting for a matte black finish with a splash of color, avoiding the loud aesthetics of some boutique pedals.
Notably,the knobs are highly tactile and satisfying to use. while it may seem trivial, the attention to detail in the design is commendable for pedals in this price range.
Ease of Use

Usability Rating: ★★★★☆
It’s somewhat frustrating to have certain functionalities concealed within the pedal.
These pedals are refreshingly simple, featuring only two or three controls on the front panel. The overdrive and fuzz pedals can operate on a standard 9V battery, while the Soft requires a pedalboard power supply.
The only usability drawback is that some advanced features of the Soft, such as trails and bypass, are controlled by internal dip switches. While this is understandable given the pedal’s compact size, it can be inconvenient to have functionalities hidden inside.
Sound Quality
Sound Quality Rating: ★★★★☆
Keeley Suns Ultravoid Fuzz

I have a Russian Big Muff that I’ve used with the same guitar and amp since 2003, and it hasn’t changed settings in two decades. The Suns has that same ‘set and forget’ quality.
The Suns is an evolution of Keeley’s previous Moon pedal, which received feedback regarding its low-end response. The tone stack of the Suns has been redesigned to address this issue while maintaining a resonant bass response.
At its core, it shares similarities with the characteristics of a Big Muff. Notably, it tends to have one optimal setting for a specific combination of guitar, pickup, and amp.
The filter offers a broad range, but I found only a few sweet spots for each setup I tested. I have a Russian Big Muff that I’ve used with the same guitar and amp since 2003, and it hasn’t changed settings in two decades. The Suns has that same ‘set and forget’ quality.
As indicated, it’s a fuzz pedal that responds differently based on the gear used. It shines for lead parts with a neck single coil but excels in rhythm playing with a Les Paul-style bridge humbucker. It rewards confident, legato playing, making any mistakes painfully obvious.

A boost in front gives it a kick, but the Suns isn’t lacking in either volume or gain.
The Suns features multiple gain stages typical of op-amp fuzz pedals, and you might expect that such a saturated pedal wouldn’t benefit much from gain stacking. However, that’s not the case here. A boost in front enhances its performance, but the Suns is already robust in both volume and gain.
Keeley Super Bass Overdrive And Distortion

The Super Bass is outstanding. Even as a fuzz enthusiast, I must admit that this pedal captured my attention the most. I’m a fan of the recent Marshall reissues of the drivemaster and Guv’nor,and this JFET amp-in-a-box serves as a fantastic,affordable choice.
It performed well with every amp I tested, irrespective of the guitar used. However, it truly comes alive when paired with a real tube amp, especially when the level is set past 1 o’clock. The result is a punchy,tight blend of saturation from both the pedal and amp compression.
I found that using a punchy boost pedal in front allowed for even more articulate gain, regardless of the amp’s voicing and wattage.
While there are low-gain tones available from this overdrive pedal,achieving them requires some tweaking. Similar to a ProCo RAT, it can sound a bit ‘scratchy’ at lower gain settings, particularly with humbuckers. Though,this can be easily remedied by adjusting the tone control or tweaking the guitar’s tone pot. In my experience, it performed better with single coils at low-gain settings, but that’s subjective.
Nonetheless, the real excitement with this overdrive pedal comes from cranking the gain as high as possible while keeping the volume up on your amp. It can handle everything from ’80s rock to modern metal, especially when gain-stacking is involved. I found that a punchy boost pedal in front allowed for even more articulate gain, regardless of the amp’s voicing and wattage.
When used with my Marshall stack, the Open setting proved to be more versatile, while the Closed mode, with some EQ adjustments, delivered a heavier and more resonant sound for chunky riffs. When switching to a DAW amp simulator, the Closed mode recorded exceptionally well, capturing the same magic feel as a stack pushing air in the room.
Keeley Soft Reverb

The Soft is a high-quality reverb pedal, even if its spring reverb mode is somewhat basic. Nevertheless, it performs well and fulfills its purpose. I believe the primary audience for this pedal consists of players seeking a ’set and forget’ spring reverb for smaller amps lacking a reverb tank. The plate reverb mode, however, is where it truly shines.
At lower Dwell settings, it provides a subtle alternative to shorter spring reverb tones. Conversely,at higher Dwell settings,it delivers that distinctive metallic,almost glassy plate reverb sound.
A tone control for the wet signal would be a valuable addition. Even for shorter reverb lengths like spring emulation, it can be beneficial to soften the wet sound.
The timbre of plate reverb can be perfect for specific parts. I found that long, legato lead sections with the Suns paired exceptionally well with the plate mode on the Soft. For busier sections, I dialed back the reverb level to around 9 o’clock.
this highlights the only drawback of this reverb pedal: the absence of a tone control for the wet signal. Even for shorter reverb lengths like spring emulation, having the ability to soften the wet sound can help the main part cut through. However, this is a minor complaint considering the pedal’s price point.
While it may not be a primary selling point for many potential buyers, the most intriguing feature is the ‘soft focus’ mode. This mode alters several parameters using the Dwell knob, effectively creating a single-knob ambient reverb. It combines reverb with two delay lines, resulting in a four-voice chorus. The final output is surprisingly subtle, given the complexity of that description.
Final thoughts

The value of each pedal will vary depending on your current setup.These pedals not only offer great sound quality but also come at an attractive price point.
However, if your pedalboard is already equipped with fuzz and drive options, the suns and Super Bass may not catch your interest. On the other hand, the Soft serves as a fantastic multi-functional reverb pedal, especially for those lacking a spring tank in their amplifier.
From our observations,while some musicians prefer a straightforward reverb pedal,enthusiasts frequently enough own several. Genres like post-rock, shoegaze, or ambient music may lead players to seek more specialized reverbs, such as granular, reverse, or shimmer effects. Typically,high-end reverb units encompass a variety of these options.
Guitar World Verdict: the Super Bass stands out as the most remarkable of the trio. It’s user-friendly, delivers excellent sound across various amplifiers and setups, and is priced lower than many competitors. as a JFET drive, it offers a unique topology that many players may not have on their boards. The Suns, while impressive, faces stiff competition in the op-amp fuzz market, while the Soft caters to a niche audience.
