Why no 5 star?
It’s actually 4.9 on my scale…
I play YouTube music on it and mix my guitar into it,
All just by mini,
Two speakers,
Both play the same sort of thing,
As it’s stereo system
As a guitarist I would like mono music, but one speaker just for me…
Pretty please with sugar on top 🫣

Chords detection not working

Auto chords detection stopped working, it get stuck analyzing and doesn’t generate any chords even after song is finished

So much fun with endless possibilities!

I have been having so much fun exploring the tones. I also really enjoy playing to the back tracks. I play a lot of different genres from flamenco guitar ,blues ,rock ,funk , reggae,and metal. and the spark amp and app makes it so easy to play whatever I want when I want without having to switch a whole bunch of equipment. I really love it.

Spark Pedal app won’t update, looper doesn’t work, Bluetooth issue…

I was excited to get this, Positive Grid tones always sound great. I purchased right away just received today 9/16/26, I am frustrated and bummed to b find the looper will not sync with neither my iPad or iPhone, the app syncs with my pedal when I try and sync “bluetooth audio” it will not find it even though my iPad and iPhone both are synced to “Spark”. The app says there is a “app update” but when I try and “update now” it just takes me to the app in the App Store and says “OPEN” not “UPDATE”. I touch OPEN and it still isn’t updated, I’ve tried about 10 times. I don’t know if I’ll keep this if the looper function is not accessible on the pedal as this is one of the main reasons I purchased it. Hopefully they get their act together and UPDATE the app so the pedal itself can be UPDATED. GRRR I was excited to use this, now I’m just frustrated.

Free?

If this is supposed to be free with purchase, why is it asking me for payment info. I’m locked out if I don’t give payment info that Spark does not need in the first place? WEAK.

Slight adjustment

It would be absolutely great if you can add “MOD” and “EQ” in two different sections as this would make creating tones a WHOLE lot easier

Just needs a bit more organization

Being able to separate tones into genres is nice, but there HAS to be a way to organize inside the genre menus. Being able to drag presets up and down would be ideal or even organize them alphabetically. The way they just organize them by date created is SO clunky

App won’t update

App won’t update, brings me back to the listing on the App Store. I open and goes back to the update page. Please help

Ai

The ai on this app is by far the worst I’ve ever used. By a country mile. It would follow any and I mean any of my prompts. If I could give this a zero I would. Try to use the Lava Amp.

Mostly amazing

Mostly amazing, sometimes chord analyzer doesn’t work but mostly works

Best guitar gadget ever

I’ve bought several mini amps from Vox to Blackstar to Fender and the Spark is by far the best I’ve used. Well worth the money.

UP and downs of Spark

Great sound on headset and great modeling others tones yet poor quality of standards for craftsmanship buy warranty’s

Groove Looper not fit for purpose

The Groove Looper drums slip out of sync with the guitar loop. It seems the guitar loop is recorded on the Spark 2 and the drum loop is streamed from the app, and the two gradually slip out of sync with each other which makes the whole thing unusable after a minute or two.

I reported it to support and they claim it’s being looked into, but there doesn’t seem to be any fix coming. Meanwhile Positive Grid continue to advertise this as a feature of the Spark 2 amp, despite knowing it doesn’t work.

Don’t buy Positive Grid

Hardware is not bad, actually fun… BUT:
Lives and dies with the app.
While they successfully manage to include new features to throw ads for more hardware in your face, the maintenance of the app is poor at best.
iPhone app has a bug since more than a year where chords can get blacked out just when you want to read them.
iPad app: normally, when you restart a just played YouTube song, stops playing sound on the amp. You have to manually swipe the slider for it to resume playing the backing track.
Both iPhone iPad : some YT tracks cannot be stored. Don’t show in recently played nor saved songs.
The list of saved songs is not curated. Just by time added, no other way of sorting them (and that would be so easy to fix… says the SW engineer).
Each a minor thing but in the sum painful. this hardware is useless without GOOD app support.
And they seem not to use their apps or just don’t care. Idk, decide on your own.
And who really cares about all the AI bs.
I regret my purchase.

Blue tooth is starting to cut in and out.

Had this for a few years and now the Bluetooth keeps cutting in and out. Suggestions?

Works for Bass, too

I have enjoys using this system more than any other headphones and pedals. Still love to feel the bass through my amp, but when I have to be ‘quiet’ this makes it more enjoyable. Love the ease of setup and AI for getting bass tones similar to a song or group.

What a find!

I got the SparkGO after trying other small amps like Boss Katana and was just disappointed with tone and abilities. Saw someone mention the GO and just took a shot in the dark. I genuinely rate it as one of the best purchases I’ve ever made. You can create virtually any tone you want, can save 4 presets permanently offline if you want, play backing tracks to jam on and I can even fit it in my guitar case for travel.

5 stars: give me a pitch shifter/harmonizer pedal please.

It’s Okay?

I’m sure at one time this app was cutting edge. However, it has started to decay. Features that I’m sure were once popular are starting to break. Will it be updated before rigor mortis sets in?

Prime example, there is only one in app purchase, Experience Jimi Hendrix. It is displayed right across the top of the screen. It is unavailable for purchase. The content has expired.

I’m sure for advanced users who only use this for tones are happy. Those function well. For the use of learning new songs, this is straight up clunky. Designing new tones with AI is greeted with the experience of the keyboard overlaying the navigation buttons. You are forced to decide if the tones you have are good enough, or if it is necessary to use the AI, then force quit the app and go through repairing.

The saved song list (just one list, no option for playlists, unless you’re an Apple Music subscriber) has no customization and no search. If you saved more than a few songs, you will be forced to scroll through your entire list in the reverse order of which you added it. You will also be subject to looking for the title of whatever the person who uploaded it to YouTube named it.

The app is still usable, but letting it rot makes me mindful that my physical amp is only good for as long as this software is maintained. I like the product, but it makes me question if I should continue to invest in Positive Grid gear, or if my money would be better spent buying a dump amp and fancy pedals. Having easily customizable tones is cool. The amp is great. As far as using the app for anything but guitar tones, you would be better off getting a $20 annual Ultimate Guitar subscription.

Lots of bugs

The app constantly tells me to connect my Bluetooth audio even though it is connected so some of the features never work.

It always says to register my device even though I’ve done it sever times.

Connecting my spark control is a whole process every time. It never just connects, I have to hold down the button on the device.

Great sounds but connectivity is really poor
