The Koogo Plexion is a mini distortion pedal from Koogo, a maker of compact effects pedals. It is built around the sound of a Marshall Plexi-style distortion, meaning it aims to reproduce the character of that amp's overdriven tone in a stompbox. It is an analog pedal with a true bypass signal path, a single footswitch, and a small footprint suited to tight pedalboards1.
The pedal is listed at $31 USD1.
The controls and Normal/Bright switch
The Koogo Plexion keeps its control set simple: three knobs and one toggle1.
| Control | What it does |
|---|---|
| Volume | Sets the pedal's output level |
| Tone | Shapes the brightness of the distorted signal |
| Gain | Sets the amount of distortion |
| 2-way toggle (Normal / Bright) | Switches between two overall voices |
A single footswitch turns the effect on and off1.
The Normal/Bright toggle is the pedal's main voice switch. In Normal it gives the darker of the two settings, and in Bright it pushes more high end forward, which can help the pedal cut through at lower gain or with a darker amp. The same toggle arrangement appears on the closely related Rowin Plexion, where Rowin's own product page describes it as "a toggle switch to switch between Bright and Normal sounds"2, and a retailer listing for the Rowin LEF324 Plexion Distortion describes the same feature as a lever switch for changing between bright and normal sounds3.
Because the Tone knob and the Bright toggle both affect high end, the practical approach is to set the toggle for the overall character you want, then fine tune with the Tone knob. Players comparing it with other mini distortions in the Koogo line, such as the Koogo Distortion and Koogo Super Distortion, will find the Plexion is the one voiced around a Plexi-style amp rather than a general-purpose distortion1.
Questions
Is the Koogo Plexion true bypass?
Yes. The Koogo Plexion is listed with true bypass, so when it is switched off the guitar signal passes through without the pedal's circuitry in the path. It has a single footswitch to turn the effect on and off.
What power supply does the Koogo Plexion need?
The Koogo Plexion runs on 9V DC power. It is a mini enclosure pedal, so plan for a standard 9V DC center negative power supply and pedalboard space accordingly.
Is the Koogo Plexion analog?
Yes. The Koogo Plexion is an analog distortion pedal, not a digital model. Its signal path is listed as analog.
Where is the Koogo Plexion made?
The Koogo Plexion is made in China, like the rest of the Koogo range of mini effects pedals.
