The fretboard is completely flat, described as having an "infinite radius", similar to a classical guitar or a flat surface like a table.

The Vigier's 90/10 neck system with a carbon strip is praised for unparalleled stability, ensuring the neck remains immovable over time.

The flat fretboard allows for microscopically low action without fret buzz, a feature praised by multiple owners.

Vigier ships the Shawn Lane Excalibur with an impressively low action of 0.7mm on the treble side, showcasing its precision setup capabilities.

Achieving low action comparable to Vigier is more dependent on excellent fretwork than fretboard radius, with some users achieving around 1mm on well-leveled frets.

Users running light strings (e.g., 9-42) report a smooth bending experience, allowing for nuanced control over notes.

Despite lacking a tilt joint, upper fret access is reported as not being an issue for users.

The ball bearing tremolo system is highlighted as exceptionally smooth, enhancing playability during vibrato and bends.

Owners express high satisfaction, with some claiming it as the best guitar they've ever purchased, even without prior experience with Vigier guitars.

The Excalibur's flat fretboard allows for low action without fretting out during bends, contrasting with other guitars where fretwork often limits action height.

Players appreciate the flat fingerboard for its even string action, benefiting both lead playing and complex chord voicings.

Factory fretwork often requires improvement; Vigier's setup quality is likened favorably against brands like PRS and Gibson, which sometimes have inconsistent fretwork.

The 24.75-inch scale length combined with a flat fretboard is noted as a unique feature, distinguishing it from other models.
