The KMA Machines Chief Disruptor is arguably the ultimate rendition of the Muff-style fuzz, featuring tons of options to get your perfect sound, including 3 Gain modes, active EQ with adjustable and switchable Mids controls, Top-Boost circuit and Clean Blend with Pre- or Post-EQ options.
Chief Disruptor Controls
The Chief Disruptor features 3 gain modes:
"Tight" - A more modern, tight and focused sound; less bass and super-crisp harmonics.
"Vtg" - Vintage mode is classic Muff with a balanced frequency response.
"Heavy" - Thick sustain, big low end and rich mids.
Use the Disruption control to crank the gain to your liking, from light drive to crunchy rhythm tones, saturated lead sounds and crushing doom fuzz.
The Chief Disruptor's powerful EQ section gives you control over sculpting your sound. Active Bass and Treble controls give you up to 15dB of boost or cut, while the parametric Mids EQ with adjustable centre frequency (100Hz to 2kHz) gets you from scooped tones to mids-focused and even cocked-wah effects.
You can adjust the Mids EQ on-the-fly using an expression pedal for wah-like quacks or phaser-like sweeps. You can also adjust the Q of the Mids-EQ using the internal trimpot.
Use the Mids footswitch to activate the Mids EQ - perfect for screaming solos, giving your chord work some emphasis or adding some filter action!
Engage the Top-Boost circuit with the toggle switch for a cutting boost that punches through the mix. You can adjust the level of the Top-Boost using the internal trimpot.
Use the Clean Blend control to give your fuzz or distortion tones some of the clarity and attack of your dry signal.
Use the toggle switch to specify whether your dry signal is inserted Pre- or Post-EQ for different characters - Pre-EQ is a more cohesive sound, while Post-EQ ensures your dry signal is unaffected by any EQ tweaks.

I spent an obsessive amount of time checking out univibe pedals. I'm so glad that I purchased this one from Boost. It is simply fantastic! If you don't believe me, then check out some video demos. Thanks Jim! + JG
This is a fantastic drive pedal. There’s plenty of Plexi style pedals out there and I’ve owned a few, this one stood out for the switchable A/B-B/A switch. The boost side is nice and simple, much like an LPB-1. Not overly clean but a perfect partner to the drive side. The Plexi side is again nothing revolutionary but very good all the same and sounds great, on a par with far more expensive pedals.
The build quality is also top end, very neat and tidy. Squeezed into the single enclosure and with a lifetime warrantee I couldn’t ask for more. I don’t think this’ll be leaving my pedal board any time soon!
Lots of great sounds in this relatively-compact delay / reverb
I’m only just starting to scratch the surface of the KMA MACHINES Cirrus, but absolutely loving it so far. Very responsive to pick attack which means can really control the “ambience” with playing style. Really looking forward to exploring further.
Had a few vibes, absolutely loving this one, check the YT demos, lovely satisfying vibe with all the swirly goodness you could hope for. Beautifully made and reasonably priced. Highly recommended - and Jim at Boost is a top guy
I came across the Formula B Fuzz Rangers via online demos on Youtube, and they all sounded so good that I had to get one. Looking online I found the Boost Guitar Pedals website via the Formula B website as a listed UK stockist. Jim was excellent and the pedal arrived when he said it would and it was perfectly packaged. I would have no hesitation in buying any other product from Boost.
As for the Fuzz Rangers, it is a great pedal. I had to work at it a touch to get the sounds I liked from it, but it seems to react really well to different guitars and different amps with adjustments to volume and tone on the guitar and different amp settings. I found it works best into a slightly cranked amp, and volume roll-off on the guitar offers a great variety of sounds from clean to classic fuzz. Thoroughly enjoying the pedal. Well done Jim, great website and a great selection of interesting brands and pedals..... Which one next????
Having used a number of univibe clones over the years this one truly nails the sound for me, it comes with some clever additions in a pedal board friendly size and is excellent value for money. If you want the true sound of the original this pedal delivers.Special thanks to boost Guitar Pedals for putting this deal together so quickly..
I'm still working my way through all the sounds, but so far I'm loving them all.
Each time I think I've got a fav sound I flip the diode switch and there's another one. Great value for a four-in-one fuzz pedal!!
Both modes really useable. The first can get a wooly or starved/wolly sound or more nasally raw sound depending on how you dial it in.
Mode two can be more mid focused and with both switches down it's just a real nice deep, warm wall of fuzz. Great stuff.
Awesome pedal. Does everything from short slaps, to long endless delays, or echo-verb. The infinite delay feature on the button hold is interesting, though if you need a certain sound out of it like that, you have to be okay with the sound that those settings create when the infinite hold feature is off. I’m sure it will be great for recording some interesting textures, but I don’t think I’d use it live, as the infinite hold sounds glitchy and cuts off very quickly at some of the shorter, more subtle delay settings that I use. The art on the pedal is nice, and the build quality is solid. Comes with a carry bag, for some reason, but I can’t complain. A great unit by any standard, but especially good quality and features for the ticket price.
