The JHS Morning Glory V4 is one of those pedals that shows up in everyone’s signal chain conversation, and for good reason. It’s a Marshall Bluesbreaker-derived overdrive with a very specific personality: cutting, mid-forward, and assertive. Whatever you think “transparent” means, this pedal has its own take on it, and once you hear what it actually does, you’ll know immediately whether it’s your thing or not.
I find the Morning Glory pretty opinionated about frequencies. It has a noticeable mid hump, not as pronounced as a Klon or a Tube Screamer, but it’s there. There’s also a significant bass cut baked into the circuit. The result is a sound that carves right through a mix, which makes it excellent as a lead boost or for cutting rhythm parts, but it does mean you’re getting a shaped voice rather than a neutral one.
The panel runs Volume in the top-left, Drive in the top-right, and Tone below Drive on the right. On the left, a toggle switch flips between the standard gain mode (LED goes blue) and the high-gain mode (LED goes red), which adds a meaningful boost in saturation and feels like a second, hotter pedal sharing the same enclosure. On the side of the enclosure sits the high-cut switch, which trims the top-end brightness when engaged.
In the demo above I’ve set up a Drive Sweep so you can hear the full gain range from clean to crunch, and a Gain Toggle sweep that cycles between the two modes at a fixed Drive setting. There are also separate High-cut On and High-cut Off snapshots to show exactly what that side switch does.
At moderate Drive with the standard gain mode, the Morning Glory sits in Edge of Breakup territory: open and dynamic, with the notes blooming into a light crunch when you dig in. Push the Drive further and you get into a tighter, more compressed crunch, though the heavy bass cut keeps it from getting thick or muddy. The Heavy Crunch preset (Drive at 9, Tone rolled almost all the way down, high-gain mode engaged) shows how dark and focused it gets when you lean into it.
The high-cut switch is subtle but useful. Flipping it on doesn’t kill brightness dramatically; it just takes a bit of edge off, which can be welcome if your rig is already on the bright side or if you’re running into a clean amp with lots of top-end air. The Drive Sweep makes it clear that the character of the mid-hump stays consistent across the range. It doesn’t turn into a different pedal at low Drive; it’s always recognizably the Morning Glory.
The EarthQuaker Devices Plumes is the other modern low-to-mid gain overdrive that comes up in the same conversations. The Plumes is based on the Tube Screamer topology: soft clipping, a mid-hump that sits a bit lower and rounder, and a bass cut that’s present but noticeably less severe. It also has three clipping modes that let you go from a nearly-clean boost to a crunchier, filthier overdrive. The Morning Glory is simpler and more opinionated: it does one fundamental voice, and the gain toggle gives you two intensities of that voice rather than a different character altogether. If you want flexibility and a warmer, slightly more rounded overdrive, the Plumes has the edge. If you want a pedal that cuts through a dense mix with no negotiation and you like that assertive mid presence, the Morning Glory is the sharper tool.
I’ve put it head to head on the same loop with a few of these, so you can switch between them mid-phrase: BOSS Blues Driver BD-2W vs JHS Morning Glory V4, EarthQuaker Devices Plumes vs JHS Morning Glory V4 and JHS Morning Glory V4 vs MXR Sugar Drive.
This pedal earns its place as a lead boost or a cutting rhythm overdrive in a band context. Single-coil pickups into a clean or slightly-dirty amp is the sweet spot: the bass cut and mid hump work together to give clarity and presence without getting honky. Humbucker players can make it work, but the bass cut can leave things feeling a bit lean. If your overdrive ideal is big, warm, and full-bodied, look elsewhere. If you want your guitar to be undeniably heard in the mix, the Morning Glory delivers on that every time.
