Waterfall Bubinga
Bubinga (Guibourtia spp.) is a dense hardwood native to Central and West Africa, known for its rich reddish-brown color and striking waterfall figuring, where the grain forms flowing, wavy patterns. This natural effect creates a sense of depth and movement, enhanced by the wood’s natural luster. The grain is typically fine and interlocked, giving it both durability and a smooth finish. Highly valued for its visual complexity and strength, waterfall bubinga is a sought-after choice for decorative and high-end woodworking applications.
Lovely Curves
S-Series tops are not only bent on the armrest which keeps intact the beautiful grain, but they are also inlayed, which seamlessly integrates the top to the body.
Supercharged. by Belforti
UltraElectronics
Our S-Series comes equiped with our Ultra Electronics.
Like the name suggests, the Ultra Electronics are a supercharged, boosted version of our electronics. It is paired with our AURA IV Pickups Family, which retain the architecture of the AURA III family, but replacing the magnets with Alnico 8s.
These are the most powerfull, precise, and pulling magnets available. They are not only powerfull, they preserve the natural sound of the instrument and are not to modern or aggressive like ceramic or neodymium.
Just tell your sound engineer before playing, you've been warned.
Pickups
2 AURA IV-J

The stacked architecture minimizes noise, ensuring a hum-free performance while maintaining the dynamic highs and punchy mids. Ideal for genres requiring sharp clarity and detail, the AURA IV-J adapts effortlessly, offering a cutting-edge sound with vintage warmth.
