Guitar World Verdict

The Gonkulator certainly has unique covered, but is arguably too niche to move the needle, even if it is a cool pedal in the right section of the right song.

The Gonkulator is a re-imagining of one of the most eccentric pedals from DOD’s 90s stable, the Gonkulator Modulator. 

The Gonkulator Modulator is a divisive pedal in that you’ll probably either love or hate. It was created by smashing together the company’s FX69 Grunge distortion and a ring modulator. The controls – suck, smear, gunk and heave – didn’t exactly help the player find their function. Then again, part of the joy for fans of the pedal is this obliqueness, forcing the player to experiment. 

On the original, the carrier frequency for the ring modulator was fixed. Although there was a trimpot inside the pedal, it was not intended to be changed by the player.

The reissue is more ergonomic, and the carrier frequency is now on the outside of the pedal, allowing full control over it. This unlocks some radically different options for the ring mod. The controls – gain, distortion, output, frequency and ring – now describe their function, allowing the player to dial in all the wacky modem sounds they could want.

With the ring mod dialled back, there’s an unusually voiced distortion useful for off-the-wall lead parts. Still, even with the controls on the outside, the Gonkulator essentially does one thing.

There are no rhythm sounds here or wider versatility. It’s an unapologetically strange pedal, and this reissue will corner the market of players who want something this strange on their pedalboard. If ring mod is your thing, then the Gonkulator also works well on bass guitar.

If anything, it’s easier to see how in alternative or indie contexts it could be used on bass for attention grabbing lines in a breakdown or pre-chorus.
