The Carl Martin PlexiRanger is an analog guitar pedal that combines Plexi-style overdrive with an adjustable treble boost. It features separate Plexi and Boost channels, each with its own footswitch, covering everything from light crunch to fuller overdrive and a more pronounced signal for solos.

• Analog Plexi-style overdrive and treble boost
• Separate Boost and Plexi channels with dedicated footswitches
• Variable frequency boost from 250 Hz to 5 kHz
• Lo-Cut with three settings for adjusting the bass range in the boost signal
• Clean boost and Range control up to +15 dB
• True bypass and Remote connection for Boost

Separate drive and boost channels

The Plexi channel features Gain, Tone and Level controls. Gain adjusts the amount of overdrive from light crunch to a more saturated drive sound, while Level sets the overall output level. Tone functions as a high-cut control, allowing you to reduce the treble and adapt the sound to your guitar, amplifier and pedalboard.

The Boost channel is activated independently with its own footswitch and delivers up to +15 dB of clean volume boost. It can be used to raise the level, drive an amplifier's front end or add more impact to a passage. When both Boost and Plexi are active, the boost signal is fed into the drive channel, which can produce more gain and long, violin-like sustain, even at lower Gain settings.

PlexiRanger can be used on its own in front of a clean amplifier, to drive an amplifier that is already close to breakup, or together with other pedals.

Adjustable frequency boost

The Freq selector determines the frequency range to be boosted, while Range controls the boost strength. The range from 250 Hz to 5 kHz extends from fuller mids to the focused top end and bite associated with a classic treble booster.

Lo-Cut reduces the low frequencies in the boost channel in three steps: none, light or heavy reduction. This can help keep the low end tight and reduce a heavy or muddy sound. With low-cut disengaged, a fuller frequency range is retained.

Controls and connections

Each channel has its own footswitch and LED indicator: red for the Plexi channel and green for Boost. PlexiRanger features true bypass, routing the signal outside the pedal's circuitry when the effects are disengaged. The Remote connection can be used to switch the Boost channel on and off with a latching switcher, such as the Carl Martin Octaswitch.
