Which should you buy? Here's the honest call, pulled from our full The Best Guitar Amps for Practice and Home: 4 Compared (and One to Skip) comparison.
The Katana-50 Gen 3 is the most complete amp here, sounding great quietly at home yet ready for a jam or small stage. The Spark 2 is the pick if learning tools, jam-along features, and app-driven tone matter more to you than raw power.
BOSS Katana-50 Gen 3
Buy itThe do-everything modeling combo that sounds convincing at whisper volume and still fills a room.
- Independent testing and owners consistently praise its natural, tube-like feel
- Deep effects and amp voicings, plus a Power Control that keeps the tone alive at low volume
- One 12-inch speaker gives it real headroom for jamming with others or small gigs
- Editor app unlocks huge tweakability without forcing you to use it
- Heavier and larger than a desktop unit
- The sheer number of parameters can overwhelm a first-time buyer
Positive Grid Spark 2
Buy itA smart practice amp built around learning and jamming, with an app that does the heavy lifting.
- Standout practice tools: auto chord recognition, AI backing tracks, and a smart jam feature owners love
- Big library of tones plus Bluetooth streaming and USB recording in a compact body
- Rechargeable battery and footswitch support add real portability
- Approachable for beginners while still deep enough for tinkerers
- Best features live in the app, so panel-only control is limited
- Not loud or punchy enough to hold its own in a full band
