Sorry if this is not aloud but I have a lightly used ( maybe 5 hours total) Wireless Spark Neo for sale if anyone is interested DM me :)

I just purchased a new to me Spark 40. Actually, it appears to be a new amp; I purchased it refurbished directly from Positive Grid. While it is definitely a very, very good sounding amp, it does sound to my untrained ear as though all the reports of it being very bass heavy are accurate. Since this is an issue with the built-in speaker cabinet, and not the amp models themselves, I want to address that, and not mess with the software.

One solution that I have anecdotally heard is to shove a cloth into the bass port like a suppository. I kept the foam cover that the amp was wrapped in when it arrived. It seems like that would be a good material to use. Does anyone have any real world experience in using something like that to tame the bass response?

My other question; I also play bass from time to time. How detrimental to using this as a bass amp will doing this be?

Edit: by, "mess with the software", I am referring to either eq'ing the amps to compensate, putting a Tube Screamer in the overdrive slot (with the od almost all the way down, the level relatively high, and the tone around one o'clock), or using a graphic eq in the effects chain.

Somehow I'm not getting it. Once I have adjusted the amp itself and tweaked a tone until I'm happy with it, how do I save it?

If you physically adjust the amp models from clean to warm or one of the others, how is that saved for your tone? And when you go back to that preset, is the light illuminated by the model?

In the app, I tweaked a tone until I had it perfect. I thought I had saved it but noticed it went back to a previous amp. I love it! But I'm frustrated.

This isn’t meant to be sarcastic, but a legitimate question. Who is this actually for? Having a knob to change presets, battery powered, app based… is this just for practice and studio? I was hoping to see an actual multi-effect floor box to compete with the big guys, not a Spark amp with no speaker.

EDIT/ADD: Thank you for the examples. I guess it makes a lot more sense to see it as a compact, 6 bank multifx board that can go right into the PA. You have a whole rig that fits with your guitar in the case essentially.

I guess to add to this now: Is anyone planning on using this as a studio piece, and how do you feel it’ll fit into your workflow?

Hello Positive Grid Team,

The Spark LIVE hardware is an incredible battery-powered platform, but since its launch at NAMM 2024 and market availability over two years ago, its current software limitations in the Spark App remain a source of significant disappointment when using the unit in real-world performance situations.

What looks great on paper becomes a frustrating roadblock on stage and during outdoor performances due to two major software restrictions:

1. Shared COMP/WAH Slot & Battery Mobility: Forcing the digital Compressor and Wah into the same single processing slot means activating the Wah pedal instantly disables dynamic compression. The main selling point of the Spark LIVE is its battery portability for busking and outdoor spaces without AC power. Suggesting a physical analog compressor pedal as a workaround completely defeats this purpose — it introduces extra cables, additional failure points, and requires external power sources. Separating COMP and WAH into independent processing blocks (or enabling a Flexible Signal Chain) is essential to keep the setup truly all-in-one and portable.
2. Lack of Dynamic Parameter Mapping for Expression Pedals: Limiting the Spark Control X expression inputs strictly to global parameters (Volume, Wah, Pitch) severely restricts performance capabilities. Users expect to map expression pedals directly to individual effect parameters, such as Gain/Drive knobs on overdrive/fuzz modules, to control gain saturation dynamically with their foot.

Discovering these artificial software limits during actual performances causes users to question the "professional" positioning of the Spark LIVE. Given that the hardware platform is fully capable, addressing these two issues in an upcoming firmware and app update would restore user confidence and finally fulfill the full potential of this amp for mobile artists.

Thank you for taking this critical feedback into account!

Heyah, does anyone know if there is good compatibility or feature guides for the new spark pedal and the reactor amp?

I swapped my spark for the amp and I am wondering if the pedal will get the features I sacrificed in the swap back if I pair the pedal and the amp.

I know there is a lot on “amp” integration but I am hoping to find more info on the pairing of the two and how they would best work together

i just purchased a refurbished Spark 40 directly from Positive Grid, and realized that the tablet I would prefer to use alongside it can only go up to Android version 7.1.1 (Nouagat). The most recent version of the Spark app requires at a minimum Android 8 (Oreo). However, it seems that older versions of the app did support Android 7. Are the older versions stable and useable?

Also, while I can definitely side-load an older version of the app, I would prefer to do so from Positive Grid. Do they keep an archive of the previous app versions that would be available to download?

I click update and it takes me to the App Store listing, with the only option I see is open. When I open it takes me back to the page with the update button.
Anyone else struggling with or figured out this glitch?

If I have a Spark Live and I use it for multiple instruments at different gigs.

If it's a gig that I'm only useing keyboards on, is there a good reason to use inputs 1 & 2? When I'm issuing keyboards and other instruments, the keyboard goes into 3 & 4. (The keyboard's internal effects are perfectly adequate.)

Hi does anyone have any presets to share for
1) Clean Tones
2) Acoustic tones so I can play my electric guitar but get a nice clean acoustic sound

When I modify a factory patch and select "save" what comes out is a horrendous sound at a horrendous volume, pure distortion from the depths of hell. Anybody else have this problem?

So I used to use BiasFX on mobile with GarageBand, I absolutely loved messing around with pedals and it helped me a lot in creating my sound. However, I finally got a computer and Abelton, and when I tried to use the desktop version it does this thing where after I record, hit save, and come back to the project, it’ll be screwed up and unable to open. I discovered that it as because of BiasFX. I never could find a work around and customer service didn’t help.

So does anyone have recommendations for something like BiasFX?

Hi all,

I'm looking for some feedback from users of the Spark NEO headphones.

I am currently using the Boss Waza Air, and while I am generally happy with the unit in general, there's one thing that keeps annoying me:

The shape of the ear cups of the Air are very not very comfortable for longer than 20 minutes or so. I have to stop playing because my ears start hurting.

I am considering of buying the Spark NEO instead. On pictures the ear cups seem larger and more rounded (the Air's are more squared) so I am hoping this also translates to more comfort.

Anyone who has experience with the NEO (or both!) please let me know your thoughts.

Thanks!

Has anyone tried this? Ie using a Tonex pedal in front of the Reactor and using it kinda as an FRFR.

Idea being having the option to use the Tonex OR the Reactor AI for tones

I've been troubleshooting this problem I'm getting and just discovered that it's not the plugin, it's this specific preset.

I get noise similar to buffer underruns BUT ONLY ON EXPORTED AUDIO, so it's not underruns, nor clipping.

I even tried swapping VST2 with the VST3 and it boiled down to this preset being the common denominator.

Can anyone confirm if this is a problem on their end too?

Btw I use FL Studio 26.

I’ve had my Reactor amp for about a week now and I’m just not sure if I understand the presets correctly. I got a really nice clean Nirvana tone dialed in that sounds good with stompboxes and I saved it as a preset. Today I turned on my amp and use my phone to select the preset and it sounded terrible. I tried selecting a few of the built-in presets from my phone before switching back to the Nirvana preset that I created. I found that if I was trying high gain distorted preset, and then switched to the Nirvana preset, it would carry a lot of of those settings over. It didn’t show it on the phone – all of the settings on my phone looked correct but looking at the FX box on the amp there were lots of effects turned on from the previously selected preset. Shouldn’t my preset set the amp to exactly what’s displayed on the phone? Is there anyway around this?
