Overall a great doubler which has become my "instant gratification pedal"

Djibi-FI 03.02.2026

I've been using the pedal for a few weeks now and I have been really happy with it as I find the doubling and stereo width convincing and pleasant.
What I really like:
- Good tracking and stable doubling (the sound doesn't jump in the stereo space).
- Can give a very wide stereo effect and the time knob is effective for tightening or loosening the effect without having to go to the extreme.
- The build quality appears to be good.
- Rather transparent and respectful of the tone.
What I like less:
- No USB. If KMA were to refine their algorithm, the pedal couldn't be updated.
- The artwork: KMA has many pedals with very nice artwork but the Geminus looks a bit more "plain" to my eyes. Something like the Endgame would have been so nice!
- The tiny knobs: I'm not very fond of mini knobs and would have preferred standard size ones which I find easier to manipulate.
In conclusion, I think that the Geminus is one of the best doubler currently available.

Excellent doubler

Eoin jennings 06.06.2025

Bought this as alternative to the Mimiq which I have and rate. The addition of the Modulation mode looked interesting and for me is the key advantage over the Mimiq as it adds a sound for 80s metal that is hard to get other ways. It does rely upon TRS cable which means I had to get an old blood noise endeavours split meld to fit into my rig and an extra TRS patch cable. Also find for some reason when I turn on power it doesn’t seem to power up automatically and have to remove and insert the power cable again - have tried a few cables and power supplies so not sure why

game changer

m_siqueira 22.06.2026

I'm using the geminus in a live band context where I'm the only guitar player. It became an always on pedal - I'm using it with a low blend, tight delay and almost full wideness, in order not to sound like 2 guitars but one much wider guitar. It's amazing... Everyone in the band was commenting on how the guitar suddenly feels much bigger and it notoriously improved the sound of the band on the PA as well. It's one of those things, after doing gigs for so many years.... I wish I had had this much sooner!

Better than TC Electronic Mimiq

Guitar gadget geek 26.07.2026

After comparing the KMA Geminus to the TC Electronic Mimiq (I had both but returned the Mimiq), the KMA Geminus sounds much better. I especially like the option to turn off or adjust the pitch modulation, which the Mimiq does not offer. The Geminus sounds more natural and organic. I did have to adjust the level knob to a high level to obtain unity relative to not using the pedal, but it was possible. The finish of the pedal box looks a bit handmade because it is, but more important is how it sounds. Designed and made in Germany quality. It is now one of my always ON pedals on my pedalboard. I use for bass and regular guitar. I prefer the time knob at 9 o'clock for a subtle addition to the sound, adding more fullness and depth to the sound without sounding digital or artificial.
