Positive Grid Spark Go BK

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.

The amp has power enough to be used on any room at home, but it is its portability that is killer! Your amp at your hands! Who would say?! You can take it anywhere. Mine is always inside my single cut or start case. Even at home, for any out of the blue jamming session or practice I use it instead of a more "real amp" I own.
Another perspective is how easy is to use it with the software simulating a good set of amps, and effect pedals. At home, there are 3 of us using it, and we all feel that this contributes a lot for a personal excitement and achievement while we can play sounding like our idols - this is great to foment kids to explore music more and more. Thanks PositiveGrid!!

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.

To start off this interview - I'm not a gearhead, and I don't even know much about analogue amps to begin with - I can identify what I like and what I don't, and I can set up a nice tone on an amp that sounds right to me. Digital amps were a mystery to me, so when I started running into ads about this little thing I was quite skeptical - small speaker, and configure your sound through a phone app, where your tone is essentially crafted with a neural network? Thought this could be useful as a practice amp at the very least. Boy, was I wrong. The little thing is (can be) loud as hell - you're not gonna be playing any live shows with it, but for such a tiny speaker, it can go pretty loud when you crank it up while practicing. It also doubles as a bluetooth speaker, which is very useful for playing with live audio. The app is versatile and useful as well, outside from having preset tones and the ability to create custom ones, you also get a bunch of handy stuff including a very responsive tuner. The battery life was also shocking - it took me weeks of (not very consistent, on-and-off) playing to fully drain the thing. It charges with a USB - which can also be plugged into your PC, and guess what, it directly transmits the audio so you can use it as an audio input to even record stuff with this. There's also an Aux output, which you can use to connect to headphones, or even a loudspeaker at a band practice.

All in all, for 100€ this is an insanely good little amp. I probably won't be playing live shows with it, but it is gonna be a part of every single guitar-playing session I undertake from now on.

This is a powerful amp whose scope exceeds the mere purpose of amplifying your guitar. The first thing that you get is how solid and well protected the device is, and how every single aspect of its construction is an amazing piece of design. It is quite compact and portable, yet the sound is killer. The integrated app is simply amazing from the beginner budget point of view, as it will allow you to experiment with different amps and effects, so that you can get clear ideas of what to look for when you are planning to make the next steps in your electric guitar gear. If you are already an advanced player, you will also find yourself with several features to play with, even while it is not an option to carry on much more that just your guitar and your Spark Go.

The only comment I would add is the fact that, for solo silent practice, it indeed supports headphone output through a standard 3.5 mm jack, but it does not include Bluetooth transmission to your wireless headphones, which would be fantastic. The Bluetooth connectivity on-board only enables the amp to act as speaker for you to play your music through from any of your devices, or to connect it to the mobile Spark app to unleash its functionalities while playing your instrument, whether it is listening through the amp itself of your plugged-in headphones.

Apart from that, it is an incredible guitar amp, Bluetooth speaker and training support device.
