Compact Excellence: A Micro Amp that Surpasses Expectations
Alienproject 02.02.2024
In the realm of ultra-portable guitar amps, this product stands out as a testament to exceptional design and functionality. Despite its compact size, the sound quality is remarkably good, providing a satisfying experience for practicing sessions. The accompanying app is a highlight, boasting a well-thought-out design that enhances the overall user experience.

One particularly impressive feature is the amp's volume, which proves to be more than adequate for effective practice sessions. The convenience of the app further extends to the ease with which presets can be searched, simplifying the user's journey to find the perfect sound.

However, a minor inconvenience surfaces in the absence of a feature to sort presets based on their like counts after a search. While this may not be a deal-breaker, it is a noteworthy point for those who value quick and efficient preset navigation.

In conclusion, if you seek a micro amp that defies its size with excellent sound quality, convenient app functionality, and ample volume for practice, this product is a standout choice. The only minor drawback lies in the inability to sort presets by popularity, but overall, it remains a top-tier option for musicians on the go.


Amazing little amp. Great for a practice in a small room.
silencio 10.12.2023
Good quality material, feels sturdy. Very versatile because of its small size, fits into most of guitar cases. battery powered. Connects to a phone/computer with bluetooth. Lots of tones. Very easy and intuitive to use. Ability to plug in the headphones, and to store presets.
Of course, it will not sound like a big, expensive amp. But for a practice in a small room, outdoors its a great choice. Just what i needed. A small companion. I tend to practice at home at the speaking volume anyway, and for that this amp does exactly that. The amp probably is designed for more distorted sounds, but I play mostly clean guitar and its really good. Just have to spend some time dialing in the tone that you want, and there are endless possibilities regarding that.
I use it at mid-to-low volume, meaning - never put it at 100% volume. And its just for practice ant speaking volume. If you need the sound to fill the room, probably look for another alternative, or get a bigger one. This tiny amp is not meant to be tortured.

Piccolo, ma che bomba ...
FrankyLig 10.11.2023
Avevo già letto della qualità dei prodotti della Positive Grid, ma questo piccolo Spark Go mi ha davvero sorpreso. Perfetto per lo studio, suoni credibili (in particolare se consideriamo le dimensioni), app di gestione molto ben fatta, qualità costruttiva impeccabile.

Klare Empfehlung - Best in class

Ich war auf der Suche nach einem Kopfhörerverstärker für die Benutzung mit meiner Squier Tele 40th Anniv VB. Nach Recherche viel die Wahl auf Nux Mighty Plug MP-2, Fender Micro oder Positive Grid Spark Go.

Zunächst hatte ich den Nux Mighty Plug bestellt, allerdings verursachte dieser in jedem meiner getesteten Ohrhörer (Technics EAH DJ 1200 und Apple Earpods) ein unerträgliches Fiepen. Zudem wahr der Klang sowohl ohne als auch mit Effekten eher sehr mau und nichts Besonderes. Das Fiepen konnte nur über eine extreme Einstellung des Noise Gates verringert werden, wodurch der Gitarrenklang stark beeinträchtigt wurde und nicht mehr fürs Spielen geeignet war. Nach Recherche im Internet scheint das öfters aufzutreten.

Daher habe ich diesen Nux Mighty Plug zurückgeschickt und mir einen Spark Go bestellt. Ein Unterschied wie Tag und Nacht! Ein wirklich guter Klang und sehr viele, sehr gut ausgewählte und abgestimmte Varianten für Overdrives, Amps, etc. Der Sound mit Kopfhörer ist wirklich Klasse. Den Sound über Lautsprecher hatte ich zunächst als ein Gimmick abgetan, aber nach den ersten Tests: Wow - was Positive Grid aus dem kleinen Maß herausgeholt hat ist wirklich top.

Die zugehörige App ist auch genial: Ton-Settings aus der Cloud, AI Jam Sessions, etc.

Tipp: Mit Kabel mit gewinkeltem Steckerabgang steht der Verstärker sicher.

Eine klare Empfehlung!
