Main characteristics: Body and neck material: 100% carbon fiber with 3-layer weaving of the top deck. Pickup and electronics: Enya SP1 AcousticPlus 2.0 smart system with a built-in actuator for integrated effects. Size and scale: 41 inches (4/4), nut width — 1-11/16″ (43 mm), scale length — 25-3/4″.

Key advantages: Environmental resistance: The carbon body is not afraid of temperature and humidity changes, does not dry out or crack unlike wood. Built-in effects without connection: The AcousticPlus system uses the guitar body as a resonator, allowing you to play with Reverb, Delay, and Chorus effects directly "dry" without a combo amplifier. App and Bluetooth connection: You can adjust the equalizer and effects via a mobile app, as well as transmit backing tracks via Bluetooth directly into the guitar body. Elevated Neck: The neck is fixed in a cantilever manner without adhering to the deck, which increases the resonance and sustain of the top panel. Direct recording (OTG): The Type-C port supports the OTG interface for recording sound directly to a smartphone or computer. With delivery from Amazon, it was 650 USD.
