Portable desktop amps may now not only integrate similar technology to full-size gear but they are also viewed seriously in direct contrast to larger traditional amplifiers. A good example is contrasting the Yamaha THR30ii to the Boss Katana – both are excellent amplifiers in their own way, but can one replace the other?

We’ll compare the Boss Katana and the Yamaha THR30ii in this review to see if the Yamaha desktop can outperform the ever-popular Katana. If you are interested in these models, keep reading our Boss Katana Air vs Yamaha THR30ii review for more information below.

Winner of Boss Katana Air vs Yamaha THR30ii: Boss Katana Air

The Yamaha THR30ii is without a doubt one of the greatest desktop-type amplifiers available. The tones are fantastic, and the style is stunning, with elements such as a tube glow from behind the speaker grille – of course, this is a completely solid state, and there are no tubes in the device, but it looks fantastic.

The Katana, on either hand, is one of those uncommon amps that travels nicely between at-home training and bangers, as well as small-scale gigs. It provides excellent tones, effects, and amp models.

Boss Katana Air

Description: The Katana-Air seems to be a tiny amp head due to its elongated rectangular design and carrying handle, but lo and behold, a pair of three-inch speakers are positioned below the controls behind the front panel’s black metal grill.

Features: When supplied by AC, the amp produces 30 watts of output, which is reduced to 20 watts when powered by batteries to save battery life.

The top panel houses all of the amp’s controls, which include knobs for amp type (brown, lead, crunch, clean, and acoustic), gain, volume, bass, middle, treble, boost/modulation, delay/FX, reverb, and master, as well as nine buttons for boost/modulation, delay/FX, reverb, tap tempo, Bluetooth linking, power on/off, and engaging channel A, channel B, or front panel settings.

This amp is excellent for intermediate to advanced performers. It works well as a practice amp but lacks the power to be a good performance amp. Even if you’re an expert, it may come in handy as a home amplifier. It can also function as a Bluetooth speaker, making it perfect as a Home Entertainment System.

You might even use it in small settings, but for larger venues, you’ll need to upgrade to something more powerful, like as the Katana 100. If you primarily play acoustic guitar, the Katana-Air is not a good choice. Katana-Air is fantastic, but it is not a viable alternative for a solid acoustic amp.

Yamaha THR30ii

Description: The THR30II Wireless resembles the original amps in appearance. Its clever cream metal front and top, with subtle chrome embellishments, is just as beautifully done.

Features: A long, clean row of glossy, black, fluted knobs at the top sculpt your sound with boost, EQ, and effects. A tiny numerical LED panel, numerous inputs/outputs, including wireless, and five user memory buttons are also included. The item is finished with a simple chrome carry handle that adds to the vintage feel. 

The back and sides are made of durable, molded, textured black plastic that can withstand a few hard hits and then some.

A USB connector and two quarter-inch lineouts are located in the center of the back panel, allowing you to connect it to your computer or audio interface for recording. The THR30II Wireless is significantly larger than its THR10II siblings – the THR10II Wireless and THR10II non-wireless – and weighs slightly more, but it’s still small enough to fit on a bookshelf or desk.

The bigger form factor of the THR30II Wireless has also allowed Yamaha to give direct top panel accessibility to its 15 amp versions, which is an essential feature for many guitarists. More on this later.

The new Wireless moniker may include the most significant set of enhancements. Yes, the THR30II Wireless may be used without any kind of guitar cord. With Bluetooth, you can connect Yamaha’s THR Remote app for deep system modifications and stream backing tracks to rock along.

Boss Katana Air vs Yamaha THR30ii Voicings for Amps

The Katana is pre-loaded with 5 amp voicings from which to select. There’s a cleaner channel, a crunch broadcaster, a lead channel, an acoustic sounding, and lastly Brown, a replica of the legendary Boss Waza Craft amp head.

The tones on each preset are quite amazing, and the clean voicing provides plenty of headroom for an analog pedal board if that’s what you’re using. It also handles the built-in FX beautifully. We really liked the lead voicing’s precise emphasis.

Boss Katana Air vs Yamaha THR30ii Effects

Effects players seeking genuine effects modeling should strongly consider the Boss Katana. It has a plethora of built-in effects, 60 in all, styled after some of Boss’ most well-known and beloved stompbox pedals.

We were able to generate some amazing signal chains using the Boss Tone Studio software, in addition to editing and modifying the FX.

Boss Katana Air vs Yamaha THR30ii Speakers

When it comes to speakers, Boss Katana is the obvious winner. This is a classic-looking combination amp with a 12″ speaker in a big cabinet. The Yamaha THR30ii comes with a pair of 3″ stereo speakers that offer excellent tones at low volumes.
