Hi I have quite a few guitar multi effects which I run in my studio, ie Ampero stomp, Pod go, Mooer GS100. which I'm really happy with. I'm looking for a mini practice amp to use primarilly with headphones away from a studio environment but it must be versatile and good quality, i've been looking at the valeton GP-5, the Spark go or the Sonicake Pocketmaster. Can anyone add to this or recomend a better unit. TIA

I have the original Yamaha THR 10, sitting under my monitor in front of me right now. It's a great little amp with the bonus that it's also a very good aux. amp. Built-in USB audio device too. This video is very good...

 

Have a look at Nux they make a few small amps. The "Mighty lite bt mkII" and the "Mighty space" you can use your own IRs, both can be used as audio interface via USB-C. The Mighty air is also good although its a bit older.

 

Hughes & Kettner's Spirit Nano series mini amps might be interesting to you:

 

Main restriction is SIZE
Small amp = small speaker

I can get a good sound with Celestion Super 8 (or clone) speaker.
But smaller ... pure crap.

I use now a NANO Vypyr + portable multi FX (iphone or GP5 ...)
Once again, anything smaller than 8 inch will crap out, whatever the signal quality in itself.

If you don't want speaker but headphones, Valeton GP5 is the best option (i just ordered one :D )
Sonicake pocket master NAM conversion is very bad (frequency response s*cks) compared to GP5.

I use sometimes iphone alone + Irig HD 2 (used) and plethora of free/cheap amp sims, with headphone.

 

I've a Vox AC4TV that I like very much. I bought it used for 100 bucks. I usually play it at 1/4 watt because of neighbors (I have good ones who understand my sometimes need for banging on a drum or two, plugging in an electric guitar or mixing at 80 dB on my monitors). One of these days I'll swap out the speaker and open the back up for some air, but as it is I get a good tone out of any guitar or pedals I put through this little amp.

 

I watch MOOER Hornet 05I
It has procesor Over bluetooth and phone aplication for presets... and USB connector for recording. Also, it can be operated with wireless footswitch... roundup.. interesting little amp...

I recently got a spark 2 I think it's pretty good for the $.

 

I just got myself a Hotone Pulze for these exact reasons, and it sounds impressively good, better than the Yamaha and the Spark.

 

Big fan of that little guy. When it came out it was in a league of its own iirc. Of course now there are more alternatives.

 

My vote for the Spark Go. It resides on my desk, gives me beautiful feedbacks - if its 20 cm away from my guitar. Loud enough to really play electric guitar, the sound can be recorded direct USB, and it sounds phenomenal.

 

I own a lekato h8 headphone amp thing, though its much more than that... Its a tiny onboard fx thing that has a phaser, reverb, delay, 10 amp sims and 10 cab sims AND you can load custom IRs, use it as an audio interface with your computer with asio, load backing tracks with bluetooth, and the flexibility of converting any speaker of any size into your practice amp with an aux cable. If you dont like the sound on any speaker, just change the IR

 

Hi Thanks for all your replies, still very unsure which is best for me, I keep alternating between the Valeton GP-5 amd the Spark Go. Once again the primary function I would be using headphones the spark go has the advantage of a small if inadequate speaker and an internal battry, but no NAM playback. yet the GP-5 has more features sound wise, but no speaker and no battry. I dont know which way to turn.

 

Maybe the AI can help you make decisions, give it a few days to work on.

Which One Might Suit You Best?
Go for the GP-5 if:

• You’ll mostly play with headphones.
  
  
• You care about having lots of effects, looping, NAM tones, and deep control.
  
  
• You don’t mind using a USB battery pack or plugging in.
  
  
• You want a more “pro” sound setup.
  

Go for the Spark Go if:

• You want true grab-and-go convenience.
  
  
• You like having a speaker for quick jams.
  
  
• You're OK with app control and more limited headphone tone.
  
  
• You don’t plan to deep-dive into NAM or complex sound building.
  

If you're still torn, consider this:

• Can you live without a speaker? If yes → GP-5.
  
  
• Can you live without NAM and deep tone-shaping? If yes → Spark Go.
  

Let me know your specific situation (e.g. home only? travel? what kind of music?), and I’ll tailor the advice even more.

Choosing between the Valeton GP-5 and the Positive Grid Spark Go for headphone use depends on your priorities, as both devices cater to slightly different needs. Since your primary focus is headphone use, let’s break down the key differences based on their features, especially regarding headphones, battery, speaker, and NAM playback, to help you decide.

Valeton GP-5

• Headphone Use: The GP-5 has a 1/4″ TRS unbalanced stereo output that’s headphone-compatible, offering authentic stereo processing for a high-quality listening experience. Users report solid sound quality for direct recording and practice, with the ability to load Neural Amp Modeling (NAM) files and Impulse Responses (IRs) for highly realistic amp and cab tones.
• Sound Features: It’s a powerhouse for sound customization, with over 100 effects, up to 9 simultaneous effect modules, and support for NAM files (50 preloaded, up to 80 storable) and 20 user IRs. This makes it ideal for dialing in professional-grade tones, especially if you’re into experimenting with amp models and effects. The Valeton Suite app (iOS/Android) allows wireless editing via Bluetooth, which is intuitive for managing tones.
• No Speaker: Lacks a built-in speaker, so it’s strictly for headphone or external speaker/amp use.
• No Battery: Requires a 9V DC or USB-C 5V power supply (200mA), which could be a drawback for portability if you don’t have access to power. It’s not battery-operated, so you’d need a power bank for mobile use.
• NAM Playback: Supports NAM files, allowing you to import thousands of high-quality amp and cab profiles (full rig captures, including amp+cab, are required). This is a significant advantage for achieving authentic, studio-quality tones. However, it converts NAM files to a Valeton format, which some users note may slightly reduce quality (e.g., -30.6 LUFS vs. -40 LUFS for native NAM players).
• Price: Around $80 USD, making it very affordable for its feature set.
• Other Features: Acts as a 2-in/2-out USB audio interface (44.1 kHz, 16-bit), supports Bluetooth audio playback, and includes a tuner, drum patterns, and a customizable footswitch. Its compact size (93.5mm x 42mm x 52mm, 237g) makes it pedalboard-friendly.

Positive Grid Spark Go

• Headphone Use: Features a 1/8″ headphone output, delivering good sound quality for practice. It’s designed for compact, plug-and-play use with a focus on simplicity. Users praise its tone quality for headphone jamming, though it may not match the GP-5’s depth of customization due to the lack of NAM support.
• Sound Features: Offers a variety of amp models and effects through the Spark app, with 4 programmable presets. While it doesn’t support NAM files, it provides access to Positive Grid’s tone library and integrates with Spotify/YouTube for jamming with backing tracks. The sound is versatile but less customizable than the GP-5’s NAM and IR capabilities.
• Built-in Speaker: Has a 2″ speaker, which is small and not particularly powerful but useful for casual, low-volume practice without headphones. It’s a nice bonus for portability, though not ideal for high-quality playback.
• Battery: Includes a rechargeable internal battery, offering up to 8 hours of playtime, which is a major advantage for portable, unplugged use. This makes it more convenient for on-the-go practice compared to the GP-5’s reliance on external power.
• No NAM Playback: Lacks NAM support, limiting its ability to load custom amp profiles. It relies on Positive Grid’s proprietary modeling, which is solid but less flexible than the GP-5’s open-source NAM ecosystem.
• Price: Around $130 USD, significantly more expensive than the GP-5.
• Other Features: Functions as a USB audio interface for recording, supports Bluetooth audio for jamming, and has a simple app interface for tone editing. Its ultra-compact size (125mm x 65mm x 45mm, 346g) makes it slightly larger than the GP-5 but still highly portable.

Comparison for Your Needs

• Headphone Use: Both devices excel for headphone practice, but the GP-5 likely offers superior sound quality due to its NAM and IR support, which allows for more realistic and customizable tones. The Spark Go’s headphone output is solid, but its amp models are less flexible without NAM. If you prioritize studio-grade tones, the GP-5 has the edge.
• Portability: The Spark Go wins for true portability thanks to its internal battery and small speaker. You can play anywhere without needing a power source or external speakers, which is great for casual jamming. The GP-5’s lack of a battery makes it less convenient unless you carry a power bank.
• Sound Customization: The GP-5 is far more versatile with its 100+ effects, NAM compatibility, and IR loading, making it better for players who want to dive deep into tone crafting. The Spark Go is simpler, which could be a pro if you prefer plug-and-play ease over extensive tweaking.
• Speaker: The Spark Go’s built-in speaker is a small advantage for quick, speaker-based practice, but its low power limits its usefulness. If you’re primarily using headphones, this may not matter much.
• Budget: At $80, the GP-5 is a better value for its feature set compared to the $130 Spark Go, especially if NAM playback is important to you.

Recommendation

• Choose the Valeton GP-5 if:
  • You prioritize sound quality and customization, especially for realistic amp tones via NAM and IRs.
  • You’re comfortable with menu-diving or app-based editing and don’t mind the lack of a built-in speaker.
  • You’re okay with using a power bank or external power for portability.
  • Budget is a concern, as it’s significantly cheaper.
  • This is ideal if you’re a tone enthusiast who wants to experiment with thousands of free NAM profiles and create professional-grade sounds for practice or recording.
• Choose the Positive Grid Spark Go if:
  • You value ultimate portability with its internal battery and small speaker for casual, unplugged jamming.
  • You prefer a simpler, more user-friendly experience with fewer customization options.
  • You don’t need NAM playback and are happy with Positive Grid’s amp models and app ecosystem.
  • This is better for quick, hassle-free practice sessions, especially if you’re often away from power sources.

Decision Tips

• If you’re primarily at home or near a power source, the GP-5’s lack of a battery may not be a dealbreaker, and its superior sound options make it the better choice for headphone use.
• If you’re frequently on the move (e.g., traveling or practicing in different locations), the Spark Go’s battery and speaker make it more practical, though you’ll sacrifice some tonal depth.
• Consider your technical comfort: The GP-5 requires more setup (e.g., loading NAM files via the app or software), while the Spark Go is more plug-and-play.
• If you’re curious about NAM, the GP-5 opens up a world of free amp profiles from communities like Tone3000, which could be a game-changer for tone exploration.

Final Suggestion
Since you’re alternating between the two, it sounds like you’re torn between the GP-5’s advanced features and the Spark Go’s convenience. Given your focus on headphone use and the GP-5’s lower price, I’d lean toward the Valeton GP-5 for its unmatched tonal versatility and NAM support, which will give you more bang for your buck and a richer headphone experience. To address the battery issue, you could pair it with a compact USB-C power bank for portable use, effectively bridging the gap with the Spark Go’s portability. Try experimenting with NAM profiles to see if the extra customization excites you—many users report being blown away by the GP-5’s sound for the price.





If you’re still unsure, check out user reviews on platforms like Reddit (r/guitarpedals) or X for real-world feedback from guitarists using these for headphone practice, or watch demo videos to hear the GP-5’s NAM tones versus the Spark Go’s presets. Let me know if you want help finding specific demos or tips on setting up the GP-5 with a power bank!

 

Ai.....lol thanks for helping but it came to a similar conclusion as myself, a slight edge to the Valeton. So I'm ok better off lol

 

GP5 can be powered by 9V pedal DC and any USB source.
You can even use your phone as power for the GP5, so you can use the phone app at the same time ;D

you can add ANY cheap used small amp if / when you need it.
Even a small acoustic guitar amp or similar.

Because the sound FX are in the GP5.

You may (potentially) even power the GP5 by the battery powered practice amp USB port, with the right adapter.
So any battery powered amp with a 5V USB port will do.
