Q-Tune™ Chromatic Instrument Tuner is the first of its kind in the DIY pedal world — a high-precision tuner with a full 2.8" LCD, offered as a solder-it-yourself kit in a rugged stompbox enclosure.

At its core, Q-Tune uses an advanced pitch detection algorithm to lock onto your note with incredible speed and stability. The dynamic display gives you real-time visual feedback in a way that’s clear, responsive, and easy to read on dark stages or bright practice rooms.

Build it yourself. Gig with confidence. Pro-level precision with DIY-level satisfaction.

✅ Why Q-tune Is Different

  • 🔬 Ultra-Accurate Tuning Engine
    Tracks pitch with high precision.

  • 📺 Big, Bright 2.8” LCD Display
    Visible in the dark, crisp on stage, easy on the eyes.

  • 👆 Touch & Tune
    Navigate settings effortlessly with a responsive touchscreen—no extra buttons, no hassle.

  • 🎚️ Buffered Bypass Option
    Clean, transparent signal when engaged or bypassed. Especially handy at the beginning of your pedalboard chain or when driving a long cable to your amp. Or, use the tuner in true bypass, your choice!

  • 🖥️ Multiple Tuning Display Styles
    Choose between several visual layouts – meter, strobe-inspired, big letter display, and more.
    (All styles support full-range chromatic tuning.)

  • 🎧 Monitoring Mode
    Watch pitch in real-time while playing – ideal for intonation and practice (using buffered bypass).

  • 📐 Top-Mounted Jacks
    Both audio and DC jacks are located on the top edge—saving precious pedalboard space and keeping your rig tidy.

  • 🔌 USB-C Firmware Upgrades
    Future-proof your build - update firmware with new feaures or improvements via USB-C using the web installer.

  • 🧰 Real DIY Experience
    No code to write, no guesswork – pro-quality parts and PCB, ready to solder.

  • 📏 Two Footprint Options
    Choose the classic 125B or tight-packed 1590B size (select at checkout).

  • 🛠️ First of Its Kind
    Q-Tune is the first DIY pedal kit to offer a full-color display, studio-grade accuracy, and a rugged enclosure – all as a legit built-it-yourself project.
