Rob Chapman shares one simple trick that will improve the sound of your Boss Katana

In recent years, the Boss Katana has become one of the most popular modeling amp families on the market, and for good reason.

But some have been slow to fully come around to the Katana, and insist that nothing comes close to the authentic tube amp tones offered by the likes of the Marshall JCM800.

With that in mind, those looking to further improve the tube-style tones of their Boss amp might want to take note of what Rob Chapman has to say – because he reckons he’s found one simple “hack” that will make all Katanas sound better.

The Katana – a Katana-100 MkII, in Chapman’s case – is certainly no stranger to such sounds. They are, after all, the objective for all modeling amps, with the Katana offering five amp models for users to play around with.

But the Chapman Guitars founder’s trick goes beyond that, and seemingly lets players use one of these models to harness the sound of the Marshall JCM800.

It’s all very simple – so simple, in fact, that we imagine it may well have already crossed the minds of other Katana loyalists.

As Chapman demonstrates, harnessing the JCM800 is as simple as selecting the Brown amp model, setting the EQ – Gain, Treble and Mid all around twelve o’ clock, Bass slightly above – lowering the amp volume, upping the power output to 100W and maxing out the master volume parameter.

The result is akin to a dynamic, cranked-power amp type sound that would perform remarkably well in a blind tone test alongside the real deal.

As Chapman later found out, his hypothesis was correct. Indeed, the Katana utilizes a class A/B power amp, which, as an unidentified guest caller from Boss management informs the Clockwork Wolf frontman, means “it responds in exactly the same way that a valve amp does.”

In practice, a maxed-out master volume – which the caller says is “the best way to get the best sound out of a Katana” – lends itself to some truly dynamic tones that will no doubt win over some purists.

But the application goes beyond simply obtaining Marshall sounds. By employing the maxed-out-master approach, guitarists can experiment with different amp models, alternative EQ combinations, and can even throw some effects in there for good measures.

Add that hack to the very, very long list of “reasons to buy a Boss Katana”.

Chapman’s experimentation with the Katana just further proves how good modeling amps have become at harnessing the tone of tube amps, and is evidence of the growing achievements of advancing amp technology.

Tube amps will, of course, forever form a part of the guitar landscape, but when a Katana can do the above at a fraction of the cost and weight – with a bunch of other bells and whistles to boot – it’s no surprise the exodus from tube to technology continues to pick up pace.
