JHS Pedals Double Dragon Lo-Fi Octave Device

In a world of perfect digital octaves, we looked backward. 

The Double Dragon Lo-Fi Octave Device is built on shoulders of 40-50 year old analog octave divider technology — the same technology that gave us the MXR Blue Box, DOD Octoplus, the Boss OC-2, Ibanez OT10, Electro Harmonix Micro-Synth, and other circuits that synth designers helped inspire. 

Pre-DSP. Pre-precision. All analog warmth. 

Play single notes and you have a riff machine. Play a chord and the circuit starts to stutter, jump, and fight itself, making something new. It's not trying to replicate you perfectly — it's trying to play along with you. 

It's alive!

The Sound

The Double Dragon is an all-analog monophonic octave-down and up effect. The lower octave is the foundation — thick, analog, with the characteristic behavior that made vintage octave circuits legendary. The upper octave is pure bonus: an octave-up distortion that lands somewhere between an Octavia and a Superfuzz. Gritty. Usable. With a mid-range sting that cuts through the mix. 

Turn on the Double Dragon and you can't help but start playing riffs. Your guitar feels twice the size. You fill out the space that used to need a band. 

A Milestone

In our entire JHS Pedals history, this is our first octave device. We've done octave fuzz but we never landed on a sub octave circuit that felt at home in our brand — until now. Weird, wild, and lo-fi. We're glad we waited to get it right. 

Who's It For?

For riff lovers. For anyone who's ever listened to Led Zeppelin and wanted that synchronized guitar-and-bass weight under their fingers. For fans of The White Stripes, Hendrix, and Rage Against The Machine, Muse, Royal Blood. Also — For bass players who know what a vintage OC-2 can do to your basslines. For creative players who want something more than digital precision and clinical accuracy. For people who want a collaborator, not just a tool.

Controls:

VOLUME controls the master output level with extra boost available. Turn the octaves off, dry full on, and you have an amazing always-on preamp. 

DRY mixes in your clean signal to the octave effects — all the way up is where we suggest you start, all the way down goes fully wet for glitchy vintage synth textures. 

OCT− controls the lower sub-octave mix. 

OCT+ controls the upper octave and distortion (activated by right footswitch).

Left footswitch is ON/OFF. Right footswitch engages OCT+ circuit. 

The main effect must be on for OCT+ to function — it's the way it's designed — not a limitation. For octave-up only, engage and turn OCT− down. 

Pairs Well With 

Overdrive after (especially Tube Screamer - mid heavy types). Fuzz after for chaos. Pitch vibrato for a more synth-like texture. The Double Dragon's tracking quirks become even more alive and useful when layered with other effects.
