Strictly limited to 12 pieces worldwide. Signed by Rob Trujillo.
Own a piece of metal history. The Godin A4 Ultra Robert Trujillo Yellow Flame RN is not just a bass; it is a holy grail for collectors and Metallica fans. Based on the instrument Rob Trujillo played at Metallica’s 2024 “The Helping Hands” benefit concert, this exclusive run is strictly limited to only 12 pieces globally. Each instrument features a headstock hand-signed by Rob Trujillo himself, making it an unrepeatable investment and the crown jewel of any collection.
Key Features
The “72 Seasons” Aesthetic Dressed in an eye-catching ’72 Seasons Yellow’ High-Gloss finish, this bass screams energy. The visual appeal is matched by its premium construction, featuring a Solid Spruce top and a Canadian Basswood body. The body is engineered with two resonance chambers, providing a lightweight feel and an airy, acoustic resonance that breathes with every note.
Signed & Certified Exclusivity This is as rare as it gets. With only 12 units produced for the entire world, owning this bass puts you in an exclusive club of custodians. The signature on the back of the headstock authenticates its connection to the legendary Metallica bassist, ensuring its value for decades to come.
A Sonic Hybrid: Piezo meets Magnetic Just like Rob, this bass needs to handle everything from melodic ballads to thrashing riffs.
-
Magnetic Power: A Lace Sensor Low-Profile pickup at the bridge delivers classic electric grit and definition.
-
Acoustic Depth: A Custom Voiced L.R. Baggs piezo system captures the natural acoustic qualities of the chambered body.
-
Total Control: With separate outputs for each pickup, you can route your signals to different amps or mix them internally. The system even includes an integrated tape saturation simulation to add warmth and compression directly from the instrument.
Professional Playability The bolt-on Maple neck features a comfortable ‘C’ profile and a satin finish for smooth transitions. The 20-fret Rosewood fingerboard offers a familiar, fast playing surface, while the Ebony bridge enhances sustain and transfer of vibration to the body.

Steve –
Ive played standard Godin A4s for years and the build quality is always top tier, but this limited run is on another level. The combination of the Lace Sensor Low-Profile with the L.R. Baggs piezo is a dream configuration for getting that punchy Trujillo tone while keeping the acoustic versatility Godin is known for. Whoever is lucky enough to grab one of these 12 is getting a masterpiece. That Yellow Flame finish is just incredible to look at.
