This beautiful electric/acoustic guitar was made by the famous Guangzhou Huayi Musical Instruments Co., Ltd., China, a company founded in 2012 and producer of much-loved acoustic and electric guitars. 

This model is your first step into the world of acoustic classic multi-sound hole instrument design, with first-rate sound, style, features and value. The rounded back is made of ABS (Acrylonitrile Butadiene Styrene), which is a type of thermoplastic polymer that's commonly used in the construction of guitar bodies, particularly in entry-level and mid-range instruments. It's valued for its durability, lightweight nature, and resistance to impact, making it a practical choice for guitar manufacturers.

This model offers guitarists maximum performance potential, and unique styling at an affordable price. It also provides clear highs and focused, balanced bass response. It is also a beautifully finished instrument with a natural top sporting vine-embellished multi sound holes, Grover-style chrome closed-back tuners, acoustic guitar peg bridge and internal piezo pickup. This guitar has an EQ-7545 pre-amp with bass, mid, treble, presence and boost sliders, a battery warning light and separate volume control. It is powered by any 9V2 battery in a slide-away battery holder. 

In general, acoustic-electric guitars with a rounded back design often offer a unique aesthetic and improved sound projection compared to traditional flat-back designs. The rounded back can enhance resonance and volume by allowing the sound waves to bounce around inside the body more freely.
