After years of building all sorts of effects pedals (but mostly overdrives and fuzzes), JHS finally entered the octave game. The Double Dragon is their first dedicated octave pedal—and they built it on forty-year-old technology. MXR Blue Box. Boss OC-2. Electro-Harmonix Micro-Synth . Those circuits that predated digital precision, that tracked imperfectly, that sounded alive rather than accurate.
The JHS Double Dragon is 100% analog, 75mA, top jacks, silent bypass. Two voices live inside: down and up.
The octave-down is the foundation—thick, weighty, the kind of sub that makes a single guitar feel like it brought a bass player along. Play single notes and you’re a riff machine. Play a chord and the circuit starts to stutter, fight itself, generate entirely new textures . That’s not a bug. That’s the point. It’s not trying to replicate you perfectly. It’s trying to play along with you .
The octave-up lives under its own footswitch. It adds a gritty distortion between an Octavia and a Superfuzz, with a mid-range sting designed to cut through any mix . Stack it on top of the sub or run it solo—just turn the OCT? knob down and let that upper voice scream.
Controls stay simple: Volume, Dry, OCT?, OCT+. Crank the Dry, kill the octaves, and the Double Dragon becomes an always-on preamp—clean boost with character .
It’s for riff lovers. For anyone who heard Led Zeppelin and wanted that synchronized weight under their fingers. For White Stripes tones, Royal Blood tones, vintage synth-bass tones on a four-string . For players who want a collaborator in the chain, not just another tool .
