Features

Private Stock Woods

When you reach the S-tier level, you're not just picking a guitar; you're choosing a masterpiece. Our Private Stock Woods represent the absolute pinnacle of tonal and aesthetic excellence, handpicked for their unparalleled beauty and unique sonic characteristics.

All of the woods in the Private Stock score between 91 and 100 on the Belforti Rating. These pieces are extremely rare and are the results of intense researchs and sourcing.

Any top from the Private Stock

Our Private Stock is where you'll find rare, heirloom-quality woods with stunning figuring, color, and unique tonal qualities.

Choose from an extensive range of options—ranging from extraordinary flame and quilted maple, to exotic woods like cocobolo and ziricote.

EVO Gold Frets

Made from a special copper alloy, EVO Gold Frets offer a perfect blend of strength and longevity without sacrificing tonal clarity. They are remarkably resistant to wear, ensuring that your instrument stays in peak condition for years, even under heavy use.

Not only do they provide a silky-smooth playing experience, but their distinct gold color adds an extra layer of aesthetic sophistication to your instrument.

Signature Pickup Shells

S-Series instruments feature Signature Matching Pickup Shells, meticulously crafted to harmonize with the overall design of your instrument. They are a mirror of our inlayed top, as the matching wood is inlayed in the shell to mimic the top of the S-Series

Signature Options

S-Series grants you access to a set of signature options amongst the most unique of the industry. Signature tuner knobs, signature neck inlays, wooden knobs and many more

Signature Inlays

S-Series Inlays are subtle, elegant rework of our standard inlays. They are an outlined version, to preserve the private stock woods' grain. They are matching your top, and extracted as one piece of wood each.

Let's wrap things up.

Every S-Series comes with our most advanced signature lutherie technique

The Wrapped Inlayed Top

Not only do you get the most rare Private Stock Tops, but instead of being blued on top of the body of the instrument, S-Series tops are inlayed in the body, and outlined with a 3 ply purfling.

This creates a seamless integration of the top in the instrument's design, gives it a natural contoured binding look, and did we mention it still follows the curve of the armrest ?

Supercharged. by Belforti

Every S-Series comes equiped with the Ultra Electronics Configuration.

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.
