Kmise Roll Boost Electric Guitar Effects Pedal Mini Single Type DC 9V True Bypass

Works great, and does what was intended. I put mine after my overdrive and distortion. Sounds great on my cleans too, allowing me to fine tune my sound. No complaints about these inexpensive KMISE pedals, I own several. Fantastic for the price with a good build quality and attractive color coded housings. Basic but does the trick.

First, I am bound to state that I received both these pedals at no cost for review. Having gotten that out of the way ...KMise Tremolo PedalWhat is a tremolo? As relates to electric guitar, tremolo is a modulation in the volume of the sound. That's all. Back in the way early days, this was an effect that could be implemented very inexpensively using the often-unused half of a pre-amp tube in an amp. This made it a popular feature for amp manufacturers, which in turn led to its use by musicians, especially back when there were basically no other effects.I have several old tube amps with tremolo, and this pedal does a pretty good imitation of the genuine article. The tremolo effect varies from almost undetectable to a full underwater warble kind of sound. I also have some more modern tremolo effects, and I think blindfolded you would be hard-pressed to tell the difference. The pedal is true bypass, the full signal goes through with the power disconnected. When the effect is enabled, the volume does go up a bit, but with basically no additional noise.I've seen some complaints that this pedal doesn't really kick in until you have the intensity half way up. Actually, more like 1/3 the way up, and that is pretty much how an old tube tremolo worked. To turn an old built-in tube tremolo off, you simply turn it all the way down, there is no switch. As far as the rate goes, this pedal is also comparable to the real thing.For the price, this pedal is surprisingly well made, with an all-metal case, and solid-feeling switch. The pots are smooth and quiet, but the shafts are plastic, not metal, and the knobs come off rather easily. The jacks are tight. There is no provision for a battery, you will need a 9 volt power supply. I use a 1Spot. The lack of a battery does not bother me at all, I never use batteries in effects. Modern batteries are awful, they all leak, you are asking for trouble.Inside, there are two stacked circuit boards, one for the electronics, and the other for input/output/power/etc. All the components are modern miniature surface-mount, everything is very neat. The jacks, switch, and pots are supported solidly by the sturdy metal case, not the circuit boards.I'm not a cork-sniffer. You can spend $200 on a tremolo pedal. Would that be better? I hope so !!! This pedal does everything you could want from it for $20. It is a terrific value - well-made, quiet, and sounds fine. I would not take it out on the road and stomp it every night with hob-nailed boots, not with those plastic pot shafts. But for bedroom or studio use, it is perfectly good, and a great way to pick up an old-time effect.Summary: I like this pedal.================================================KMise Phase PedalA phaser is a fairly simple device. It adds a swirling effect to the sound. Most 'classic' phasers have just a single control for the speed or rate of the effect. The only other control on this pedal is a mechanical true-bypass switch. This effect cannot take a battery, you will need a 9v power supply, I recommend a 1Spot. Batteries today are expensive and very poorly made anyway.Construction is good, with a strong two-piece anodized aluminum casing. All the controls and jacks are supported by the case, not the circuit boards. The only weakness is the plastic shaft of the knob, which could break if abused. That makes this pedal more suited for the studio or bedroom than the road. Mine has an error in the printing on the case - it is a "Vintage Phas". Ha.When engaged, the pedal gives you the classic phase effect, with no noise or change in volume. There's just not a lot to a phaser. I have one other phase pedal, and the two are quite comparable, this one having a more pronounced effect and greater speed range. For the price, this pedal is a great value - good sound and good construction, small enough to fit anywhere.Summary: I like this pedal.

The Hot Plexi delivers a nice, warm tube-driven emulated sound. It doesn't have a wide range of adjustments according to my taste, so it's a bit of a one-trick pony. But it sounds good when you find the "dist" sweet spot at around 10 to 11 o'clock, especially since it's priced under $20, the cheapest one I could find. Think of that 70s classic rock moderate to low-level distortion, from smooth power to all the way down to just the edge of breakup. If you're into metal/shredding, look elsewhere.It gives a noisy hum if you add a 2nd gain pedal, but in retrospect it's best when used alone since it's not really meant to be that hot.No noise issues when adding a modulation pedal such as a flanger or phaser.Very good value if you don't need the bite of a screaming hot gain pedal. That's not what this is for.Recommended.

The media could not be loaded. The Kmise Analog Chorus pedal is a wonderful choice for anyone looking for that lush, warm, and rich modulation that analog pedals are known for. It has a bright, vibrant tone with a slightly poppy edge, making it perfect for clean, shimmering chords or layered textures. For my demo, I played a riff from one of Her’s songs twice—first clean with slight reverb using the neck pickup, then again with the pedal engaged. The analog chorus added a beautiful depth and movement to the tone, really bringing out the character of the riff.This pedal has a simple layout with just two controls—Rate and Depth—but it’s all you need to shape the effect. I set the Rate around 80% for a quicker, more lively modulation and cranked the Depth to 100% for a full, lush sound. The result was a dynamic and warm chorus that sits perfectly in the mix without sounding too overbearing. Whether you’re playing indie rock, pop, or even dipping into ambient soundscapes, this pedal delivers a smooth, musical tone that works beautifully.The build is solid and compact, with an aluminum alloy casing and a clean, eye-catching blue finish. It’s lightweight and runs on a standard 9V DC power supply (not included), so make sure you have one on hand. While it’s incredibly affordable at just $20, it doesn’t feel like a budget pedal—it holds its own, offering the kind of analog richness and tonal flexibility that’s hard to find in this price range.This pedal works great for adding shimmer and movement to your clean tones or even stacking with other effects like delay or reverb for more ambient vibes. The neck pickup really complements its sound, giving a smooth, rounded tone that pairs perfectly with the analog modulation. Honestly, if you’re building a board or just looking for a high-quality chorus to experiment with, the Kmise Analog Chorus is a fantastic choice. It’s simple, effective, and sounds amazing. Check out my demo to hear how it transforms a clean tone into something truly special!

I bought this pedal because I wanted to try using a fuzz but didn't know how often I use it, since I already have a distortion pedal. I was shocked to even see a fuzz pedal for so cheap. It did an okay job, and in my opinion it had decent tone. However, with the pedal being so cheap, the connections aren't that secure, and certain settings will give you a lot of feedback, especially in my case, since I was using a guitar with very microphonic pickups. I would say it's decent for a beginner who wants to try out different effects, or a neat novelty for someone who's more experienced.

Cool pedal and for a great price. Love the sound it gives.
