Overview by GAK

The Double Barrel puts two classic JHS pedals, the Morning Glory V4 and Moonshine V2, into one compact unit, focusing on low-to-mid gain tones.

The left-hand side has the Morning Glory circuit, which provides a more transparent tone, a light crunch, and makes chords and leads vibrant. The right-hand side has the Moonshine circuit, which has that classic Tube Screamer sound, which focuses on lows, with better presences and warmer clipping than those original screamers, delivering more grit and saturation. Both circuits can be used separately or shared, giving you a wide range of tone to blend and explore.

The Morning Glory side has a Volume, Drive, and Tone controls, as well as a Gain toggle switch which engages the boost. On the side of the pedal is a Hi-Cut switch which cuts the treble, giving you more control over your sound. The Moonshine side has Volume, Drive, Tone and Clean control knobs, with Clean letting you blend the overdriven signal with your original dry signal. There’s also a Proof toggle switch which lets you select between the two different Moonshine overdrive, and there’s an Order toggle switch positioned between both sides, which lets you select the order of the Morning Glory and Moonshine section in the signal chain.

You can also connect the JHS Red Remote by plugging it into the Remote Gain input with a standard patch cable so you can switch the Gain switch toggle remotely, making it easier to use.

Powered by a 9V DC power supply (sold separately).

Overview by JHS

The Double Barrel V4 is for the player who needs a versatile but transparent overdrive at medium and light gain levels. You won’t find face-melting distortion here, but you will find overdrive with the character and stacking abilities to cover almost any tonal need. So let’s look at the Double Barrel V4 and see why it packs a one-two punch that is unrivaled.


The right side is our brand new Moonshine V2 which is a highly unique and massively tweaked version of the most famous overdrive ever created housed in a little green enclosure. The Moonshine V2 has the classic mid-heavy tones that you’d expect but with more gain, volume, and tones available than you ever thought possible. The Moonshine V2 has the same core sound as the Version 1 but we have added a new “Clean” knob to blend in the perfect amount of clean signal with your overdrive signal.

The left side of the Double Barrel is our best-selling Morning Glory V4 overdrive. Transparent and open tones are what lurks inside this circuit as well as the new hi-gain toggle with Red Remote capability. Just plug in the JHS Pedals Red Remote into the “Remote Gain” jack with a standard patch cable and you can switch the “Gain” toggle on the fly for even more tonal options. You now have five on-the-fly overdrive options to choose from in the Double Barrel V4!


When these two circuits are stacked, something magic happens. Tones that are original and fresh come with ease, as well as added flexibility, due to the “order switching” toggle that lets you decide what pedal comes first in the signal chain.

  • Endless overdrive tones from low to medium gain.

  • Updated versions of the Moonshine and Morning Glory.

  • Red Remote capability with the Morning Glory V4.

  • Order toggle to select the order of effects when stacking.

We are convinced that this is one of the greatest 2-in-1 pedals ever made… seriously. If you’re having problems getting the tones you want, just grab the Double Barrel V4 and you’ll find out how easy it is to hit the target!
