🎸 Revolutionise Your Rig: Meet the RSW 🎸 The wait is over! Introducing the RSW, our debut product that’s set to transform guitar and bass systems. 🚀 Developed in cooperation with @konviktmlv @konvikt.kustoms and road-tested by @malevolenceriff over the last year, the RSW is the ultimate solution for seamless audio redundancy. Preorders are now open, with only 50 units in the first batch! Shipping starts late February – don’t miss out. Why the RSW? ✅ All in one: No more mess of multiple switchers, power supplies, crazy cabling, MIDI splitters etc. ✅ Integrated Power: Dual 12V locking, isolated, and filtered supplies for the @neuraldsp Quad Cortex™, plus IEC feedthroughs for mains-powered units like the @fractalaudiosystems Axe-FX™ III for ultimate clean power. ✅ Auto Switching: Never worry about your primary modeller failing – the RSW can switch to your backup instantly. You/your tech can of course also switch manually. ✅ Balanced & Buffered Input: Clean, consistent signal every time. ✅ Line Level Stereo Output: Carnhill transformers for premium isolation and sound quality. ✅ Multipurpose TRS Jacks: Perfect for extra IO, FX loops, expression pedals, or controllers like the FC6/FC12. ✅ Sustainability: Built with premium, eco-conscious components. ⚡ It’s compact. It’s reliable. It’s a game-changer. 📲 Preorder now via the link in our bio – limited stock available!

Another custom wireless switcher heading out for @niallhoran 🇮🇪 Takes balanced line level from their @shure Axient system, transformer-isolates it down to instrument level, and gives an instant emergency cable backup if anything goes wrong. And an added VU meter 😁

Quick and simple custom junction box out the door for @adam_devonshire 🤙 thanks @gav_maxwell for always trusting us to get it right 🙏

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: @konviktmlv @theguitarbutler @neat.audio @calvinroffey @maxtaylorgrant @billyhutton1 🙏 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, Olly x

Custom builds are always special — but seeing one in action side stage at the @barrowland_ballroom 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! 🖤 @drewlanderr @mackmc89 @rossmcnae @sammctrusty @barrymckenna
