2026-GPX-Boss-Katana-vs-Positive-Grid-Reactor-700.jpg

This is an object lesson in Product Design, Smart Marketing and Precision Segment Targeting. I don’t think anyone has had a better stab at the Boss Katana Amps juggernaut (particularly Katana 50 and 100), than Positive Grid has with its new Reactor Amps. It’s grabbed and processed the Boss formula to a large degree and come up with its own distinct and high-quality eye-catching amp designs - with some distinct objective improvements.

 

For instance both the Reactor 50 and 100 have the exact ...

So this is essentially a late birthday present - which arrived in the 3rd week of November - so I’ve had it for a few weeks already.

 

There is still no sign of the Stand!? - which I also ordered in on the Kickstarter Campaign - nor any advice as to when that might land!

 

For the amp itself I’m hugely impressed with its build and feature set - high quality materials throughout and an incredible amount of features onboard - every other amp manufacturer should sit up and take notice! I was ...

2024-GPX-Boss-Katana-Mini-X-700.jpg

So the Katana-Mini X sits between Boss’s Katana Mini (7W) and Katana-Air (30W) both in girth and output levels. The Mini is 230mm wide, the Mini X is 287mm wide, and the Katana-Air is 350mm wide, while the Mini X is the tallest - at 200mm, compared to the Katana-Air’s and Mini’s Height of 181mm.

 

There are several points of interest to this new amp. I feel that Boss got the balance here between feature set and simplicity wholly spot-on. And besides having a superb sounding 5 Inch 10 Watt ...

You can instantly feel that the new amp is more immediate, tighter, and responsive than before - with more snap and punch to its output, and deeper soundstage projection. It benefits from additional expansive controls and output options, and now is much more controllable via direct Bluetooth App control with the Boss Tone Studio App. I would describe it as overall significantly more articulate and dynamic than before.

 

And I really love the new ’Pushed’ Amp Type - which I’ve switched over to...

8 years after its debut, Boss's Katana Amp Series evolves to a 3rd Generation Tube Logic Platform - with even greater sound, feel and response

2024-GPX-Boss-Katana-3rd-Gen-700.jpg

Somewhat serendipitously - Boss’s Katana Series was birthed in the same year that Guitar Pedal X first started - 2016. From that first MKI Series I very early on acquired a Katana 100, which of course was a long term favourite of mine. Then in 2019 Boss introduced the improved MKII Series - with the quite superb Artist MKII arriving a year later - that was to be my second Katana Amp. And now in 2024 Boss has released the Gen III Series, NOT MKIII, as this release is far more significant than a ...

DSM & Humboldt's Simplifer X Zero Watt Reverb Stereo / Dual Amplifier is a magnificent marvel of analog audio engineering

2024-GPX-DSM-Hunboldt-Simplifier-X-700-V2.jpg

I’m totally in awe of the technical prowess presented on this killer dual analog amps in a pedal format.

 

It’s actually a very compact device at just 125 x 105 x 65 mms, and carries so many advanced functions here almost entirely in the analog domain. There’s not a single sub-menu here - this is surely WYSIWYG perfection - while it does use every available surface to cram in all the technology that is needed to support all those features.

 

At first encounter this all seem wholly intuitive...

2024-GPX-Boss-Katana-GO-700.jpg

Most of you will be familiar with the $399 / €399 / £339 Boss Waza-Air Wireless Guitar Headphone Amp - which delivers the Katana Amp ecosystem within a wireless Bluetooth Headphone Set. The Amps and Effects selection is controlled by a Bluetooth connected Mobile App - and since all the processing is done inline within the Headphones you don’t suffer any wireless lag. That proposition though is rather dear for many, and very much limits the choice and style of headphone you have at your disposal...

2023-GOX-Boss-Katana-Air-EX-700.jpg

Contrary to what I originally thought - this is not a replacement for the original chrome-handled Boss Katana Air - that I featured all the way back in January of 2018, but a more grown-up higher quality sibling. It has much the same functions, control topology and operational parameters as its slightly smaller more plastic forebear - where the Boss engineers have really concentrated on the finishing details and quality of output for the Air EX model. The newer one has a few more ports / ...

Boss's New Rugged Dual Cube LX and Dual Cube Bass LX are the ultimate Grab 'n Go Amps for Indoor Use

2022-GPX-Boss-Dual-Cubes-700.jpg

I will start off with a little contextual history on Roland and Boss Amplifiers. Obviously Roland is Boss’s parent company and had the initial success with its JC Jazz Chorus amps. On the back of that success it then released a number of wedge-shaped Cube amps - essentially outdoor performer amps - which became the mainstays of journeymen buskers. If you’re out and about in London you will likely see Roland Cubes on every other leading tourist area street corner. So for the longest period it ...

2020GPXBossNextoneSpecialAmp700.jpg

Boss’s Tube Logic Series of Nextone Amps somewhat failed to garner the same plaudits and support as the lower cost Katana Range - while the Artist edition Nextone contained some particularly clever circuitry - yet those amps did not resonate as well with their intended audiences as was predicted / expected. Meaning that the Boss engineers have expended some very significant effort in the interim towards getting the new Special Amp up to the level it truly deserves to be at.
