Jackson Audio Asabi Mateus Asato Signature Overdrive Distortion Pedal

A Comprehensive "Marshall-in-a-Box" Pedal Featuring 2 Channels, 4 Clipping Modes & MIDI

Written by

Elliot Stent

The Jackson Audio Asabi is an all-encompassing modular gain pedal, featuring overdrive and distortion channels that capture the essence of Marshall's iconic Plexi and JCM800 amplifiers. Developed with Brazilian-born virtuoso Mateus Asato, the Jackson Audio Asabi pedal sounds truly magical - with every detail painstakingly refined to ensure that both of its channels work together harmoniously. Other modern-day features include a 3-band active EQ and the ability to change clipping styles for additional tone-sculpting indulgence.

In addition, Jackson Audio has developed replaceable distortion modules for Asasbi - analogue circuit boards that can easily be swapped out to fundamentally change the tonal direction of the pedal. While a range of these will be available, the pre-installed 'Modern High Gain' module gives you a plethora of the aforementioned "black and gold" sounds - ranging from classic rock to crushing heavy metal!

4 New Drive Pedals from the Andertons Pedal Cabinet - These Sounded Great!

Versatile 2-in-1 Design

Jackson Audio's Asabi is essentially a "Marshall-in-a-box" pedal that can cover all of your gain needs. With two footswitches that allow you to engage its overdrive and distortion channels independently or simultaneously; this powerful pedal gives you complete sonic authority - so you can recreate the soulful overdrive and liquid high-gain textures that Mateus Asato is known for!

Overdrive 'Plexi' Circuit

Asabi’s overdrive channel features a soft-clipping circuit that was designed to capture the smooth overdrive and touch responsiveness of a vintage Marshall Plexi. This circuit can be used independently from the distortion channel, but can also be employed to boost the front-end of that circuit in order to achieve even more gain and saturation.

'JCM800' Distortion Channel

The distortion channel of the Asabi is a high-gain, hard-clipping circuit that is based on the Marshall JCM800. You can therefore expect open yet tight high-octane tones - perfect for '80s rock or even modern metal.

For tweaking the ideal sound, you can rely on the distortion circuit's active 3-band EQ. Based on the legendary "Baxandall" EQ, this control-set provides you with tremendous sound-shaping potential - akin to the dials you'd find on a contemporary amp channel. You can also make use of internal trim pots to alter the frequency and Q of each band (bass, middle, treble) - making the the Asabi's EQ fully parametric and highly-adjustable.

4 Clipping Modes

With four different styles of clipping, each can drastically alter the tone of the distortion and overdrive channels. 'Vintage Marshall’, ‘Classic Screamer’, ‘Asymmetric’ and ‘Symmetrical’ clipping modes offer plenty of variety, making the Asabi the only gain pedal you should ever need on your board!

'Gain-Cycle' Feature

One of the Asabi's most noteworthy features is its 'Gain-Cycle'. This takes the gain knob setting and divides it into four equal parts, making them instantly accessible as steps to cycle through by simply pressing both footswitches simultaneously.

As with all of Jackson’s multi-option drive pedals, a unique circuit matches the output level of the pedal in its various clipping diode styles. So, no matter which of the four clipping options you choose, on either distortion or overdrive sides, your volume level will remain constant. This helps you to alter how the pedal interacts with your amp or any other pedal(s) you may have in your rig - completely on-the-fly!

MIDI Control

Another modern appointment found on the Asabi is its MIDI input. Offering MIDI control over clipping styles, 'Gain-Cycle' options, drive EQ options as well as on/off of the overdrive and drive circuits; the Jackson Audio Asabi is arguably one of the most comprehensive analogue drive pedals ever created and can integrate with even the most complex of setups.

Interchangeable Distortion Modules

There are other distortion modules (sold separately) available for the Jackson Audio Asabi, which completely change its tonal characteristics. This includes the 'Large Mouse' - a fully analogue circuit that harnesses the legendary sound of the ProCo Rat pedal. With many more modules in the pipeline, this concept turns Asabi into a gain pedal Chameleon!
