Boss Katana Mini KTN-MINI Guitar Amp overview from GAK

The Boss Katana-Mini is a compact, portable, battery-powered amplifier that boasts a sound quality greatly exceeding other mini amps on the market.

Churning out 7 watts of power through its specially designed 4-inch speaker, the Katana-Mini provides you with a small but powerful amplifier that can be used seamlessly for practice, jamming and street performance.

Once plugged in we were taken back by the Mini's full tone and dynamic range, in spite of its tiny size, this thing packs a punch easily exceeding other amps in its class.

Impressively, the Katana-Mini packs all-analogue input circuitry with multi-stage analogue gain and three-band analogue tone stack. Chose from three unique amp types to transform your tone, 'Clean' offers a dynamic response with great clarity, 'Brown' provides high-gain tones for heavier playing and cut-through solos. Finally, 'Crunch' adds a helping of overdrive apt for blues and rock rhythms. The Katana-Mini's simplistic interface makes it ideal for first-time players and also seasoned guitarists who are looking for a simple and portable amp option.

Notably, the Katana Mini is also equipped with a 3-band analogue tone stack, giving you an easy-to-use platform to shape your sound to how you want it. Additionally, make use of the Mini's built-in tape-style delay and reverb

Run the Mini on the move and in the streets with just six AA-size batteries, or use a AC adapter (sold separately) for indoor practise and jamming. Play to your favourite tracks via the AUX input and capture your playing with the Phones/recording output with additional cabinet voicing.

    This is a great little amp that lives out the way on a bookshelf until I need it. The batteries have lasted a month so far with light use. I've only really used it with headphones and it's usually at 50% volume or less. Also using an acoustic guitar so can't comment on electric guitar. Clean and Brown settings work best. Crunch is a bit mweh. The delay is great and it will reverb if you set level to 10 and time to zero.

    Absolutely amazing amp. Well worth its price easily. It's simple with clean to crunch to the Mighty Brown sound. If you love classic Rock and metal like I do,this will be the correct amp for you. This Boss Mini Katana will suit all your musical needs. SJ
