The Harley Benton MiniStomp Plexicon is a compact distortion pedal from Harley Benton, described by the maker as a "Classic Plexi-style Distortion Unit". It aims to put the character of a Plexi-style amp into a small stompbox: Harley Benton describes its sounds as "Defined, punchy cleans; dynamic crunch sounds rich in harmonics; a creamy overdrive typical of the much-vaunted original". It sits in the distortion family, alongside other Harley Benton drives like the MiniStomp Drop Kick and the Plexicon.1
Controls and switching
The Plexicon keeps things simple with three controls: tone, volume and gain1. A single On/Off footswitch with a status LED takes the pedal in and out of the circuit1. When it is off, the pedal is True Bypass, which Harley Benton says eliminates signal interference when switched off, so your clean signal is untouched1.
Power and connections
The pedal runs on a 9 V mains adapter with a center negative plug, and the adapter is not included1. It draws 20 mA1. Connections are a 6.3 mm jack input and output1.
There is no battery option listed: the pedal is powered only via a 9 V center negative mains adapter, which is not included in the box1.
Size and build
The MiniStomp Plexicon measures 92 x 38 x 32 mm and weighs 133 g, in a solid metal housing1. That small footprint is the point of the MiniStomp format: it takes up little more space than a standard single knob pedal, which matters when a pedalboard is filling up.
Where it sits in the range
As a Plexi-style drive, the Plexicon covers amp-style crunch and overdrive territory rather than the heavier end of Harley Benton's distortion lineup, which includes pedals like the Extreme Metal and Rodent. For more on the effect type, see Distortion Pedals and Overdrive Pedals1.

Questions
Does the Harley Benton MiniStomp Plexicon take a battery?
No. Harley Benton specifies power supply via a 9 V mains adapter with a center negative plug, and states that the adapter is not included. There is no battery option on the spec sheet, so plan to run it from a pedalboard power supply or a separate adapter.
Is the MiniStomp Plexicon true bypass?
Yes. Harley Benton describes the pedal as True Bypass, which the company says eliminates signal interference when the pedal is switched off. When it is off, your guitar's signal passes straight through to the output without passing through the distortion circuit.
Does the Plexicon come with a power adapter?
No. Harley Benton's product page states that the pedal is powered via a 9 V mains adapter, center negative, and that the mains adapter is not included. You will need to supply your own 9 V adapter or use a pedalboard power supply output.
How big is the Harley Benton MiniStomp Plexicon?
Harley Benton lists the MiniStomp Plexicon at 92 x 38 x 32 mm and 133 g. That is a small footprint by pedal standards, so it takes up little room on a pedalboard, and the light weight keeps the board easy to carry.
