JFX Pedals Deluxe Modulation Ensemble Review

When I think of guitarists with iconic, difficult-to-replicate guitar tones, I don’t think of John Frusciante. I always figured it was easy to get close enough to his clean tones with a Strat and any garden-variety tube amp, and in some ways, it is. (To me, anyway.) But to really nail his tone is a trickier thing.

That’s a task that Jordan Fresque—the namesake builder behind Sault Ste. Marie, Ontario’s JFX Pedals—has committed significant time and energy into tackling. His Empyrean is a five-in-one box dedicated to Frusciante’s drive and dirt tones, encompassing fuzz, boost, and preamp effects. And his four-in-one, all-analog Deluxe Modulation Ensemble reviewed here is another instant Frusciante machine.

The Frusciante Formula

Half of the pedal is based off of the Boss CE-1, the first chorus pedal created. The CE-1 is renowned as much for its modulation as for its preamp circuit, which Boss recently treated to its own pedal in the BP-1W. The other half—and the pedal’s obvious aesthetic inspiration—is the Electro-Harmonix Deluxe Electric Mistress, an analog flanger introduced in the late ’70s. Frusciante fans have clamored over the guitarist’s use of the CE-1 for decades. The Chili Peppers 6-stringer reportedly began using one in the early ’90s for his chorus and vibrato tones, and the preamp naturally warmed his Strat’s profile. Various forum heads claim John dug into the Electric Mistress on tracks like “This Is the Place” off of 2002’s By the Way. The Deluxe Modulation Ensemble aims to give you the keys to these sounds in one stomp.

JFX describes the DME as “compact,” which is a bit of a stretch. Compared to the sizes of the original pedals its based on? Sure, it’s smaller. But it’s wider and deeper than two standard-sized pedals on a board, even accounting for cabling. But quibbles around space aside, the DME is a nice-looking box that’s instantly recognizable as an Electric Mistress homage. (Though I wish it kept that pedal’s brushed-aluminum finish). The knobs for the Mistress-style as well as the authentic Boss and EHX graphics are great touches.

The flanger side features a footswitch, knobs for range, rate, and color, and a toggle to flip between normal function and EHX’s filter matrix mode, which freezes the flange effect in one spot along its sweep. The CE-1-inspired side sports two footswitches—one to engage the effect, and one to flip between chorus and vibrato—plus an intensity knob for the chorus, depth and rate knobs for the vibrato, and gain knob for the always-on preamp section. The DME can be set to high- or low-input mode by a small toggle switch, and high boosts the gain and volume significantly. A suite of three LED lights tell you what’s on and what’s not, and Fresque even added the CE-1’s red peak level LED to let you know when you’re getting into drive territory.

The effects are wired in series, but they’re independent circuits, and Fresque built an effects loop between them. The DME can run in stereo, too, if you really want to blast off.

I Like Dirt

The DME’s preamp is faithful to the original in that it requires a buffered unit before it in the chain to maintain its treble and clarity. With that need satisfied, the DME’s preamp boots into action without any engaging—it’s a literal always-on effect. To be honest, after I set it to low input and cranked it, I forgot all about Frusciante and went to town on classic-rock riffs. It souped up my Vox AC10 with groove and breadth, smoothing out tinny overtones and thickening lead lines, though higher-gain settings lost some low-end character and overall mojo.

The chorus nails the wonky Frusciante wobble on “Aquatic Moth Dance” and the watery outro on “Under the Bridge,” and the vibrato mode took me right through his chording on 2022’s “Black Summer.” On the flanger side, I had the most fun in the filter matrix mode, tweaking the color knob for slightly different metallic, clanging tones, each with lots of character.

The Verdict

If you’re a Frusciante freak, the Deluxe Modulation Ensemble will get you within spitting distance of many of his most revered tonal combinations. If you’re not, it’s still a wickedly versatile modulation multitool with a sweet preamp that’ll give your rig instant charisma. It ain’t cheap, and it ain’t small, but JFX has squeezed an impressive amount of value into this stomp
