JNS Inventions KLEROS Dual Overdrive

Excited to be checking out a new pedal from a new company today, as always! The KLEROS Dual Overdrive from JNS Inventions brings two classic dirt effects together, along with a slew of toggles, to help you shape and sculpt your sound to perfection. Get your favorite mid-hump riffs and magical horsey power chords ready – this one is gonna rock your world…

KLEROS is JNS Inventions’ take on two of the most celebrated overdrive circuits ever built: the iconic Tube Screamer and the revered Klon, both united in a single pedal, with the routing flexibility to run them stacked, independently, or in either order. Faithfully recreating the unmistakable voice that has shaped countless guitar tones, the left side switches between TS808, TS9, and the legendary TS10 circuits, moving effortlessly from smooth, warm breakup to the lead tones made famous by John Mayer‘s live rigs. Built on the iconic Klon circuit, the right side preserves the natural character of your guitar while adding richness, clarity, and dynamic response. Switchable Germanium and Schottky clipping excels the pedal as a transparent boost, a standalone overdrive, or the perfect complement when stacked with the Tube Screamer side.

Additional Features:

Order Toggle. A middle switch reroutes the signal path between Klon → TS and TS → Klon, letting you choose which circuit hits your amp first without repatching cables.

Buffered Bypass. Both sides retain their respective original input buffers, preserving the authentic feel of each legendary circuit while maintaining signal integrity over long cable runs.

Soft Relay Bypass. Relay-based switching delivers quiet, reliable operation with silent bypass switching and improved long-term durability.

TRS Y-Split Mode. An internal slide switch lets each overdrive operate as an independent effect via a TRS-to-dual-mono Y-cable. Perfect for loop switchers and advanced routing setups where you want full control over each side separately.

Inspired by the stacked drive tones heard in many of John Mayer’s live performances, KLEROS features selectable Tube Screamer voicings alongside gorgeous, switchable and mythical clipping, delivering everything from transparent edge-of-breakup tones to rich, singing lead sounds. The KLEROS Dual Overdrive will give you just a little boost in tone or volume if that’s all you want, but it really shines when you stack both sides and really open it up. Thanks to the JNS Inventions crew for sending this one my way – lots more info over on their website, and be sure to check out our demo on YouTube…cheers!
