🎧 Sound Quality: Big Room vs Bedroom
Spark 2:
Let’s just say this amp is more than a pretty face. With 50 watts of stereo power, it delivers surprisingly giggable tones for a “practice” amp. Thanks to the Spark app, you get access to thousands of user-generated tones, plus smart tone matching that auto-dials your sound based on what you play.
It’s like having a tone tech that never complains or judges your playing.
Mustang LT25:
Fender knows tone, and the LT25 delivers it beautifully at lower volumes. The classic Fender cleans are crisp and punchy, and the high-gain models are decent for practicing metal, though not quite as rich or detailed as the Spark.
It’s like a friendly labrador: dependable, familiar, and doesn’t eat your WiFi.
Winner: Spark 2 — more power, more tone-shaping options, more future-proof.
🤖 Features & Tech: AI Jam vs Amp Sim Simplicity
Spark 2:
Here’s where the Spark 2 absolutely sparkles. The app can display real-time chords from songs, generate AI backing bands, and even suggest tones based on what you’re playing. You can also use it as a USB audio interface for recording. Bluetooth streaming? Yep. Play Spotify through it while you noodle? Double yep.
LT25:
The Mustang LT25 has a clear, simple interface and a small screen to tweak amp models and effects. It’s very beginner-friendly, but lacks the smart integrations and real-time app magic that makes the Spark feel futuristic.
Winner: Spark 2 — it’s basically a smart amp with a PhD.
🎛 Usability: Plug and Play vs Tweak and Slay
LT25:
Out of the box, you’ll be playing in under a minute. The interface is super intuitive—even your bassist could figure it out.
Spark 2:
It can feel like a spaceship if you don’t love menus and apps. But once you get used to it, it’s infinitely more flexible. Still, if you’re allergic to apps, the Spark’s magic might be lost on you.
Winner: LT25 — for simplicity.
But: Spark 2 if you like tinkering and customizing your tone till it’s perfect.
🎒 Portability: Apartment Friendly Champs
LT25:
Weighs around 12 lbs, fits almost anywhere, and is easy to move room to room.
Spark 2:
Heavier at 15+ lbs and lacks battery power, but still manageable. Not quite “grab-and-go,” but not “break-your-back,” either.
Winner: LT25 — lighter and more compact.
💰 Price vs Value
If you’re on a budget, the LT25 is a no-brainer. But for just a bit more, the Spark 2 offers twice the power and ten times the tech.
Winner: Tie — depends on your budget and how much you value smart features.
🎤 Final Verdict: Which One Should You Buy?
- Get the Positive Grid Spark 2 if you want:
- A smart amp that can jam, record, and evolve with you.

✅ Best for beginners, minimalists, and budget-minded players: Mustang LT25
