The Carl Martin Crunch Drive is a premium overdrive pedal from the Danish maker, built around what Carl Martin calls "crisp, lively, and touch-sensitive crunch that responds to your playing dynamics." It is aimed at players who want a lower-gain drive that cleans up and opens up with picking strength, from jangly rhythm work to light blues soloing, rather than a heavy distortion1.
Controls
The pedal keeps its control set to three knobs, two of which are wide-swing EQ controls rather than the usual tone knob1.
| Control | What it does |
|---|---|
| Gain | Sets the amount of drive, up to 36dB of maximum gain1 |
| Attack | Shapes midrange frequencies, plus or minus 20dB at 1kHz, for punch and presence1 |
| Edge | Adjusts treble response, plus or minus 20dB at 12kHz, for sparkle and definition1 |
The Attack and Edge controls give the pedal a broad sweep across the mids and treble, which is where a crunch tone lives or dies. Carl Martin's product page describes the pedal as carefully voiced around that elusive touch-sensitive crunch1.
Power and switching
The Crunch Drive runs on either a 9V battery or a standard 9V adapter, drawing 12mA, and Carl Martin describes it as operating efficiently on either supply1. True bypass switching means the circuit is out of the signal path when the pedal is off; the maker says this ensures your tone remains pure when the effect is disengaged1.
Where it sits in the Carl Martin range
Carl Martin builds a family of drives in Denmark, and the Crunch Drive is the low-gain, dynamics-first option among them. If you want more gain or a different flavor of drive from the same maker, the range includes the PlexiTone, the DC Drive Overdrive, the AC-Tone, the Rock Drive, the Hot Drive'n Boost, the Panama and the newer PlexiRanger. For a broader look at the category, see the site's page on Overdrive Pedals.
Within the Carl Martin range, the Crunch Drive is described by the maker as delivering "crisp, lively, and touch-sensitive crunch that responds to your playing dynamics," with an Edge control that adjusts treble response (±20dB at 12kHz) for sparkle and definition1.

Questions
Is the Carl Martin Crunch Drive true bypass?
Yes. Carl Martin says the Crunch Drive is handmade in Denmark with true bypass switching, which the maker describes as keeping your tone pure when the effect is disengaged. True bypass means the pedal's circuit is removed from the signal path entirely when it is off, so it does not load down your guitar's signal when switched out.
How much current does the Carl Martin Crunch Drive draw?
The Crunch Drive draws 12mA, according to Carl Martin's product page. It can run on either a 9V battery or a standard 9V adapter, and the maker describes the pedal as operating efficiently on either supply. At 12mA it is a light load compared with many digital pedals.
Where is the Carl Martin Crunch Drive made?
Carl Martin builds the Crunch Drive by hand in Denmark. The company has been under new ownership since January 2024, when it was transferred to Thomas Svenstrup, owner of DanGuitar.dk.
How much gain does the Carl Martin Crunch Drive have?
Carl Martin rates the Crunch Drive at up to 36dB of maximum gain. The maker says that range spans from subtle chord crunch and jangly rhythm tones to light blues soloing, so it sits on the lower-gain end of the drive spectrum rather than covering heavy distortion territory.
