The G·4 Signature embodies the full expression of Belforti’s modern double-cut design — compact, precise, and unapologetically powerful. Every element has been refined to deliver immediacy and authority without excess, resulting in a guitar that feels both responsive and deeply grounded.

Its symmetrical body and sculpted neck joint offer perfect balance, while its dynamic tonal core rewards touch, intent, and emotion. Built for players who see the instrument as an extension of thought, the G·4 Signature turns discipline into expression and force into finesse.

Electronics

At the heart of the G·4 Signature lies a set of Seymour Duncan P-Rails — a complete tonal architecture in one instrument.

This system offers three distinct voices per pickup: P-90, single coil, and humbucker, switchable with effortless precision. It’s an elegant way to move from crystalline clarity to rich midrange growl or saturated drive without ever changing guitars.

The result is a sonic powerhouse — versatile, dynamic, and transparent — giving the player access to every register of tone without compromise.
