JHS releases PHERB phaser-reverb pedal, designed in 35 hours

JHS Pedals has released the 3 Series PHERB, a combined reverb and phaser pedal, the maker says was decided, designed, prototyped and approved for production in 35 hours in October 2026. JHS calls it "the fastest pedal we have ever made"¹.

The pedal runs a dark, lo-fi reverb into a four-stage phase shifter, recombined with the dry signal. JHS describes the phaser as vintage style, "think Phase 90," with the feedback left off and the notch sweeps moved up the frequency spectrum. Both effects are on at all times: there is no blend, no order switch and no way to run one effect without the other, except that turning Speed fully counterclockwise in normal mode disables the phaser¹.

The controls are Mix, Speed and Length, plus a BREAK toggle. Mix sets the amount of reverb and phaser, Speed sets the phaser rate, and Length sets the reverb decay time and pre-delay, which rise together. BREAK, with the toggle up, runs the incoming signal through what JHS calls an "asymmetric bitcrusher" with analog-style clipping before the reverb and phaser; the phaser cannot be switched out in that mode¹.

Input is a 1/4-inch jack on the right side and output a 1/4-inch jack on the left. JHS warns that exceeding 9VDC voids the warranty¹.

The pedal answers requests on the JHS Facebook fan page, comment sections, Discord and inbox for a "Flerb," a reference to the Flerb setting on the Electro-Harmonix Holy Grail reverb. JHS founder Josh Scott, who wrote a book on Electro-Harmonix, said he declined to build that combination and built a phaser inside a reverb instead¹.

JHS says the plan began as a novelty for its fans and became a production pedal after the first prototype produced usable sounds at every knob position. The maker also states the pedal is not intended as a vintage-style spring reverb or a precise phaser for clean chords¹.
