Yamaha THR VS Boss Katana Mini — Mini Amp Comparison
🎛️ Desktop Amp Showdown
Two of the most popular desktop mini amps ever made — the Yamaha THR5 and the Boss Katana Mini — go head to head in this 7-minute comparison. Landon runs both amps through clean, crunch, and high-gain tones to find out which one sounds better and whether the price difference is justified.
The Yamaha THR series has a devoted following for its warm, vintage-voiced tones and sleek desktop design. The Boss Katana Mini punches back with its 3-band EQ, three amp modes, and a price tag that undercuts the Yamaha significantly.
Both amps are battery-powered, both are genuinely portable, and both have their own distinct sonic personality. The question is which one fits your playing style better.
🔊 The Contenders
Yamaha THR5
Yamaha's desktop amp series is unlike anything else in the mini amp world. The THR5 simulates five classic amp types, has a built-in stereo speaker system with a passive radiator for bass, and produces a warm, full sound that feels much bigger than its size suggests. The glowing faux-tube aesthetic is a bonus.
- 5 amp types (Clean, Crunch, Lead, Brit Hi, Modern)
- Stereo speaker system with passive radiator
- Built-in effects (Chorus, Flanger, Phaser, Tremolo, Delay, Reverb)
- USB audio interface built in
- Aux input for playing along to music
- Battery or AC powered
- Warm, vintage-voiced character
Boss Katana Mini
The Katana Mini brings Boss's renowned amp modeling to a tiny, battery-powered package. Its standout feature — a proper 3-band EQ (bass, middle, treble) — gives it a versatility edge over most mini amps. Three distinct amp voices (Clean, Crunch, Brown) cover a wide tonal range.
- 7 Watts, 4" speaker
- 3 amp types — Clean, Crunch, Brown
- 3-band analog EQ (bass, middle, treble)
- Built-in tape delay
- Aux input for jamming
- Headphone/recording output with cab voicing
- 6x AA batteries or AC adapter

🎧 How Each Tone Compared
✨ Clean Tones
The Katana Mini edges ahead clean — tighter, more defined, with better high-end clarity. The Yamaha THR5's clean has a warmer, rounder character with a subtle room reverb quality that feels very studio-like. Both are excellent — it comes down to whether you want crisp or warm.
🔥 Crunch Tones
The THR5 wins crunch — the warm mid-range and natural-feeling breakup give it a vintage amp character that's genuinely satisfying. The Katana Mini's crunch is tighter and more modern. Community consensus: the Yamaha's crunch has more character, the Boss has more control.
⚡ High Gain (Brown/Lead)
Both amps deliver surprisingly usable high-gain tones for their size. The Katana Mini's "Brown" mode is warm and compressed. The THR's "Lead" and "Modern" modes have more bite. For heavier playing, the Katana Mini's 3-band EQ lets you dial it in more precisely.
