Carl Martin PlexiRanger Guitar Effect Pedal

Our take on the classic treble booster – expanded, refined and made unmistakably Carl Martin 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. But those powerful rigs also 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. More bite, more presence, and a raw, expressive overdrive that became part of rock history. When we designed 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 of PlexiRanger is inspired by the classic treble booster circuits we all know, but carefully voiced to be more flexible and predictable. From subtle high-end lift to aggressive upper-mid push, we designed it to add clarity and authority without becoming harsh or brittle. But we didn’t want to stop at recreating the past. That’s why we added a dedicated gain channel. With PlexiRanger, we wanted a pedal that could 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 we expect from a proper analog circuit. Used in front of a clean amp, a breaking-up amp or an already driven rig, PlexiRanger lets us shape the low end, focus the mids and 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.
