Carl Martin Plexi Ranger

Carl Martin's take on the classic treble booster – expanded, refined, and made unmistakably Carl Martin.

A Tribute to the Golden Era of Rock Guitar

• Treble booster and Plexi-style gain in one
• Midrange shaping and high cut controls
• Authentic classic rock tones
• Compact footprint
• True bypass switching

When we look back at the golden era of rock guitar – from the mid-60s to the mid-70s – we hear a sound that shaped everything that followed. British amplifiers, big cabinets, and loud stages defined the tone of players like Tony Iommi, Ritchie Blackmore, and Brian May. However, those powerful rigs came with a challenge: an overwhelming low end that needed control.

The answer was the treble booster.

By pushing upper frequencies into the front of already loud tube amps, treble boosters didn’t just solve a problem – they created a new sound. With more bite, more presence, and a raw, expressive overdrive, this became part of rock history. When we designed the PlexiRanger, our goal was to bring that sound back in a way that works for modern players, modern amps, and real-world pedalboards.

The Boost Side

The boost side of PlexiRanger is inspired by the classic treble booster circuits we all know, but it has been carefully voiced to be more flexible and predictable. Whether you need a subtle high-end lift or an aggressive upper-mid push, we designed it to add clarity and authority without ever becoming harsh or brittle.

A Modern Update

But we didn’t stop at recreating the past. That’s why we added a dedicated gain channel. With PlexiRanger, you get a pedal that can function as a pure boost, a drive pedal, or a powerful combination of both. The gain section adds body, saturation, and sustain, while still retaining the dynamics and touch sensitivity you expect from a proper analog circuit.

Versatility for Any Rig

Whether used in front of a clean amp, a breaking-up amp, or an already driven rig, the PlexiRanger lets you:

• Shape the low end
• Focus the mids
• Push the front end exactly where it needs to go

To us, it’s not just a tribute to classic British tone – it’s a practical, modern tool built to deliver that sound night after night.
