Custom Maybury Meloca Bass built for Calum Hood

This custom Maybury Meloca Bass was created for Calum Hood, bassist and core member of 5 Seconds of Summer.

Calum approached us looking for an instrument that would stand out on stage, deliver a massive sound, and align with our sustainability values.

Working closely together, we designed and built a completely unique bass using 100% reclaimed timber:

• Body: Reclaimed spruce, once used as floor joists

• Neck: White oak, repurposed from a kitchen offcut

• Fretboard: Massaranduba, salvaged from old decking

Based on our signature Meloca body shape, this bass features a bold neon green chalk paint finish paired with a pink and white marbled acrylic pickguard for an unmistakable visual statement.

Adding a personal touch, the fretboard includes a custom 5SOS star emblem across the 7th and 8th frets, while the neck plate proudly displays the 5 Seconds of Summer logo.

Premium hardware from American company Badass, including a nickel high mass bridge and sealed modern tuners, ensuring the ultimate tuning and performance experience.

Under the hood, it’s fitted with a custom Mojo reversed split-coil pickup, crafted specifically for this build and featuring nickel open-top covers. The result is a punchy, articulate tone that cuts effortlessly through the mix. The electronics include CTS potentiometers, cloth-covered wiring, and an Orange Drop capacitor, with the addition of a kill switch to allow Calum to mute the bass easily when switching between bass and keys.

The bass made its debut at the 5SOS promotional show at The Outernet in London on 4th November 2025, before going on to feature at the Times Square pop-up concert filmed for the “Everyone’s A Star!” music video.

Its striking green and pink colour scheme quickly caught fans’ attention, earning it the affectionate nickname “the Watermelon Bass.”

This project was a true collaboration, a bass designed to combine striking aesthetics, powerful tone, and sustainable craftsmanship, perfectly in tune with the energy and style of 5 Seconds of Summer.
