Luminlay Knobs
Because the Dark Shouldn’t Stop the Rock
If you’ve ever tried to tweak your volume or tone onstage in pitch-black lighting, you already know the struggle. Fumbling for knobs in the dark is less “guitar god” and more “amateur hour.” Check out the Luminlay Knobs – your glowing beacon of control in the dim backstage ether.

Let There Be Glow – Luminlay Knobs 101
Luminlay has been giving fret markers the radioactive glow-up for years. Now they’ve taken that same phosphorescent wizardry and jammed it into their control knobs, combining form, function, and good old-fashioned luminescence.
These knobs come pre-loaded with Luminlay’s signature glowing inlays – available in green or blue. They charge under light and glow when the lights go down, which means you can see exactly where your settings are without pulling out your phone flashlight like a rookie.

Green vs. Blue: Choose Your Glow Fighter
Yes, both glow. Yes, both look cool. But here’s the lowdown:
- Green Glow: Brighter, more vibrant, and longer-lasting. It’s the flashlight of the two. If stage lights are limited or you’re playing dark clubs, this is your go-to.
- Blue Glow: Softer, moodier, and a bit more subtle. Think spaceship controls, not spotlight. Great for players who want glow without the full UFO landing strip aesthetic.
Choose based on how much visibility you want… or how much you want your rig to look like it came from a Tron reboot.

Knob Construction – Not Just a Pretty Glow
Each knob is milled, then plated depending on your color of choice. These aren’t cheap plastic knock-offs. These are precision-machined control knobs with a premium tactile feel and killer durability.
You get your pick of housing finishes:
- Black – Classic, clean, stealthy.
- Cosmo Black – A slightly chromed black. Think “black tie optional” for your hardware.
- Nickel – Subtle sheen, leans vintage.
- Chrome – High-shine. Reflective enough to check for lipstick smudges mid-set.
- Gold – For when you want your gear to look as rich as your tone.
Each one brings a different vibe to your rig, whether you’re running as a minimalist or with a boutique setup that costs more than your first car.

Fitment and Compatibility – What Gear Are We Modding Today?
The MA Series fits standard 6mm split-shaft pots. That covers most Alpha, CTS, and Bourns-style pots found in guitars, amps, and effects pedals.
Designed specifically for 6.35mm (1/4 inch) solid shaft potentiometers, commonly found in many U.S.-made guitars and amplifiers, the IA Series ensures a snug and secure fit without the need for additional adapters or modifications.
For my evaluation purposes, the install is on the Charvel Marco Sfogli Signature Pro-Mod So Cal guitar. It comes stock with the Luminlay side dot markers, so I’m thinking it’s a perfect match for the Luminlay MA Series knobs. Installation is plug-and-play. No soldering. No voodoo rituals. Just remove your old knobs, slide these on, and tighten the set screw. Done.

Performance Under Fire – Literally Lit
In use, these knobs are a dream. Under UV stage lighting, the glow effect gets amplified. Hit them with a flashlight or LED for 10 seconds before you hit the stage and you’ll get solid glow time. We’re talking about an extended dosage of visibility, depending on the environment and color choice.
They’re also ideal for studio rats and ambient players tweaking tones mid-session without blinding themselves with a phone screen.

More Than Just Volume: Stack Knobs, Balancers, and More
Luminlay doesn’t stop with standard knobs. They also offer stack knobs and balancer knobs, extending that glow-in-the-dark goodness to other guitar controls. Whether you’re dialing in dual-concentric EQs or adjusting blend controls on active basses, Luminlay has a glowing solution.
These knobs come in multiple shaft sizes, covering a wide range of guitar and bass electronics. So no matter how complex your rig, there’s a Luminlay knob that can light the way.

Final Thoughts – A Knob Worthy of Your Rig
The Luminlay Knob MA Series is a small upgrade with a big impact. It’s functional, sleek, and a conversation starter. Whether you’re playing black metal in pitch darkness or shoegaze in a fog-filled room, these knobs add serious pro-level utility with a touch of sci-fi swagger.
Pros:
- Clear, visible indicators in dark environments
- Multiple housing finishes to match any gear aesthetic
- High-quality construction with smooth, precise turning
- No modification required for standard gear
Cons:
- Makes your other knobs look boring and inadequate. Prepare for a full glow-up.
- Causes spontaneous tone tweaking just to see the glow move.
- Might blind the drummer during a dark set. Wait… that could be a pro!
The Luminlay Knobs stand out as a top-tier choice for musicians seeking reliable, stylish, and functional control knobs for their instruments. Its precise engineering, coupled with aesthetic versatility, makes it a valuable upgrade for any serious player.
If you’re the kind of player who dials in your tone with surgical precision, why not see it while you’re doing it? The Luminlay MA and IA Series aren’t just for looks – it’s for control.
