Closing out the year feeling incredibly grateful and thankful.

We released the RSW back in February, and the way it’s taken off has genuinely blown us away. Seeing it trusted night after night on some of the biggest stages out there is something we never take lightly.

Alongside that, being trusted with repairs and fully custom touring rigs — including building complete systems from the ground up — has been a huge part of this year. That level of trust means everything to us.

Thank you to everyone who’s backed us with RSWs, custom gear, and repairs, and to the people who rely on our work when it really matters.

And a huge thank you to my team — Aritz, Finn, and Izaak — none of this happens without you.
Also thanks to some of the best people who helped us massively this year: .audio 🙏

This year was real growth.
Back on January 5th. 2026 is shaping up to be busier than ever, with new ground breaking products landing in Q1.

Happy holidays everyone,

Custom builds are always special — but seeing one in action side stage at the hits differently. ⚡️

We recently built a fully bespoke switching system for Twin Atlantic, designed around their Kemper rig and the exact way they run their stage setup.

This 2U unit features:
• A 3-way split from the instrument input — two feeds for the Kempers and one for the on-stage tuner
• An expression pedal input for added control
• Independent monitor outputs to check either the main or spare Kemper without affecting FOH
• Fully integrated redundancy switching — clean, fast, and tour-ready

We’ve known the Twin Atlantic lads for years, so it’s brilliant to finally welcome them into the Fretronics family with a custom build made just for them. 🤘
Appreciate you guys! 🖤

We’ve been keeping this one quiet 👀
Earlier this summer we built a full rig of custom gear for the live rig:

⚡ Output A/B Selector – switching between the main and spare Quad Cortex for each artist.
⚡ PSU System – powering 8x Quad Cortex with our own locking power cables, designed to stay secure through transport and touring.
⚡ Stage Interface – linking to each artist’s pedalboard, carrying signal over XLR, while expression pedals and tuner power are routed over CAT5.
⚡ Mini Pedalboard Boxes – compact stage units that connect back to the Stage Interface, keeping setups clean and consistent.
⚡ Sustain Box – built for the awesome , allowing the sustain pedal to be latched so the piano can ring out even when he (or Lewis) steps away.

Built for the stage, trusted by professionals. 🎶

Huge thanks to & for trusting us with this build — always grateful to be a small part of this level of productions 🙏

All set for ⚡️
A full rig of RSW redundancy systems, packed with Quad Cortex and Nano Cortex, giving the band complete peace of mind for their upcoming tour.

With automatic redundancy built in, the system keeps an eye on the signal at all times — if anything drops out, the backup takes over instantly. No interruptions, no stress, just seamless sound every night.

Driving back from now — feeling beyond proud and grateful. So many artists on this year’s lineup using gear we’ve built or repaired over the years. Can’t honestly believe this is where we’re at.

Any artists using the RSW, appreciate you so much 🙏

Huge shoutout to and sending these photos through, using the custom outboard switcher and a custom GPIO button set for his .official rig. Always incredible to see our work out there in the wild.

Two custom units off to today 🎛️ We modded 3 Crybaby Juniors to act as expression pedals, feeding into an Mastermind. MIDI goes to our box, which converts it to TRS control for the Rack Wah. The enclosure is 3D printed in carbon fibre-reinforced PAHT-CF—built tough for touring.

Thanks to for giving us this mad project!
