Update: After setting 50 presets so I could select major effect choices and combinations, I went back and modified some so distortion and reverb worked together better to achieve a nice growl effect. I put a little echo in a couple and a bit more for a "water drip" effect. Really nice! 50 is pass through and the other combinations are in group 50 also with group 10 for various distortion pedal models. I am using it with a 3-string cigar box guitar and it works amazingly well. A great value. The key to distortion is to turn treble down, after all, distortion adds high frequency content. Otherwise, it sounds harsh. I barely know how to use it. I watched a couple videos which helps to understand how to use it. I enabled a couple stages or effects layers, set the EXP parameters to WAH and calibrated the foot pedal and played with WAH effects. What buttons do is a little confusing, probably because I quickly read the manual and haven't learned the jargon yet. It won't replace individual pedals in a performance but could be used to experiment without a set of pedals. It will be fun to use it as I learn to play a guitar. Update: *** Negative is the center conductor pin of the connector. All pedals are done this way but check each device. ONLY USE A PEDAL POWER SUPPLY OR ADAPTER FOR PEDALS ! *** It has presets in 5 groups, 10 per group. I didn't like any of the original presets. I put individual effects on presets 10 - 49 and combinations on 50 - 59 for easy access. 50 is a pass through. With individual effects, I can experiment with settings then change one at presets 50 - 59 to get the desired effect. there are more individual effects than will fit in 40 presets. For example, drive effects at group 1. Modulation at group 2. Delay and reverb at 3. Amp-Cabs at 4. It didn't take long before I was editing quickly. For example, to edit, select a preset, click Stomp/edit and press buttons 1-5 to enable effects. Use the up foot switch to highlight an effects box and the one rotary button to change the type (drive, delay, filter, etc). Press Stomp again to edit the highlighted effect box. Press the 1-5 buttons to edit another. Press Settings to save. Press button 3 to save - press it twice. Then press both the up and down foot switch simultaneously to save, but check where it will be saved to. Use the up or down footswitch to change where it will be saved to. If you started editing a preset, you press both footswitches to overwrite. Change the name in Settings/Patch. Press button 2 twice to edit the name. Then save as previously explained. The effects are good but I am a beginner, not an experienced pedal user or guitarist. You are stuck with selecting presets. Individual pedals can be put in series or parallel, with the right parts, and each can be enabled as you play. But, it is a way to loop easily and select a present with the buttons. There are more settings for the WAH also, like Cry. I haven't tried that yet. Should put Cry on a preset and combo. It is small with lots of effects to try.

This is probably a very nice tool to have at a great value, IF Electric guitar is your game. I ordered this on accident as an ingnorant Acoustic player, but the customer service was a pleasurable experience. I genuinely feel bad that i had to return it already. DISCLAIMER: "I never actually powered up the pedal." But I will say that the craftsmanship of the tool was a 5 star. Lightweight but sturdy, with a sleek look and I could tell that all of the buttons, knobs, and pedals appeared to be A+.

I like this pedal im still messing around with all the functions but overall the pedal is pretty cool theres a lot of functions that are easy to use some of the effects are not really something i would use and a couple that are unnecessary like having a specific song for an effect unlesss you really just love playing that song. Some of the effects are muffled but that's probably done on purpose i haven't had a chance to use batteries in it yet but the sound quality overall is not bad i like that you dont need an amp you can plug your guitar into the pedal itself and use headphones. I like that it has drum beats on it but unfortunately they're not very customizable but still a cool feature that has decent rhythms nonetheless

Reviewed in the United States on December 8, 2025 by It's a great concept although it's not meant for rough teenagers that get overheated and try to get out of it quickly because the zipper can't withstand any resistance so I guess other than the zippers needing reinforcement it's a cool costume
Great product and experience! Just what I needed/wanted. Really cool gadget I am so glad to have! No problems. I would buy again if had a need. Thanks again and God bless! 😺❤️😊🥰🙏🐈

Great seller, customer service, they tried to help troubleshoot the best they could . Sent the first one back , refunded no issue and took a chance on a second one due to the really excellent communication from them , which let me know that the issues I was experiencing were not normal . So the second one came and after I had some time to spend with it , Wow ! I got this great sound programmed in just tweaking the sound they had preset and saved it . This is a great tool for practice , writing and just having fun . There are many drum tracks to choose from , it is really easy to dial in the BPM and change the volume on the drums . It makes practicing alone a lot better . The drum tracks are great to keep your timing up . There are many sounds I have not had time to explore yet . So far this product is really Great and I am super happy I purchased it again . The customer service is really excellent and they really seem to care about their customers . I got nothing for free or any thing so this is a honest review of my own experience . I bought three different brands of similar multi- effects units and the KMF-1 is the one I use the most and is the best of the three as far as sound quality .

I have no idea how this thing got such good reviews. It's junk! The expression pedal has no sensitivity, there's no real tone control on the individual effects, the tone quality immediately suffers when you hook this thing up, the drum machine cuts into the guitar to the point where it all just becomes a static mess. I've seen better on the market, and I should have known this thing would be hot garbage when I saw the price. If you're playing a $100 Temu guitar through a practice amp, it may be okay. But if you're playing a $2000 Les Paul with custom pickups, it will sound like a Temu guitar playing through this thing. Hell, even my cheap guitars sound better without it!
