(Shenzhen, March 20, 2026) — Hakuna Instruments (Shenzhen) Co., Ltd., a company specializing in the R&D and manufacturing of musical instrument accessories, officially launched two upgraded flagship products today: the HSAP-1201 Phosphor Bronze Acoustic Guitar Strings and the HSAB-1201 (80/20) Brass Acoustic Guitar Strings.
Building on the classic models, the new products feature core material and craftsmanship innovations, paired with a newly designed packaging. They deliver superior tone, enhanced durability, and a more premium feel, bringing guitar enthusiasts an all-around upgraded playing experience.
As widely recognized star products, the original HSAP-1201 Phosphor Bronze Strings and HSAB-1201 Brass Strings have earned the trust of countless musicians for their stable quality and high cost-performance ratio. This upgrade focuses on core performance breakthroughs, with comprehensive optimizations from the core wire to the wrap wire, achieving a triple leap in tone, feel, and durability.
HSAP-1201 Phosphor Bronze Strings: Warm, Rich & Long-Lasting Anti-Corrosion
Upgraded high-carbon steel hexagonal core wire ensures more balanced tension and significantly improved tensile strength, effectively reducing tuning instability during performance. The outer layer uses high-purity phosphor bronze wrap wire (92% copper + 8% tin + trace phosphorus), which features higher density and stronger oxidation resistance than the previous version, greatly delaying rust and corrosion.
Retaining the warm, mellow character of phosphor bronze strings, they deliver fuller mids, smooth and non-harsh highs, long sustain, and rich resonant layers. Ideal for fingerstyle, folk strumming, and studio recording, they maintain consistent tone even after prolonged use.
HSAB-1201 (80/20) Brass Strings: Bright, Clear & Dynamic
Equipped with an enhanced high-carbon steel core wire for improved toughness and stability, offering a smoother, more comfortable playing feel and easier fretting. The outer layer uses precision 80% copper + 20% zinc brass wrap wire, providing stronger metallic presence and higher sound transmission efficiency.
Preserving the signature bright tone of brass strings, they feature crystal-clear highs, solid lows, strong projection, and excellent dynamic response. The lively, elastic tone during strumming makes them particularly suitable for pop, folk performances, and live stages, helping the guitar stand out sonically.
In addition to core material upgrades, both new strings adopt a custom-designed new packaging, combining improved practicality and aesthetics. Made of thickened, wear-resistant material, the packaging offers enhanced moisture and dust protection to better safeguard the strings. With a minimalist, stylish look, distinct color schemes for phosphor bronze and brass versions, and clear product labeling, the packaging is highly recognizable and functional, convenient for both personal use and storage.
"The upgrade of HSAP-1201 and HSAB-201 is a meticulous refinement based on real feedback from musicians," said a representative of Hakuna Instruments.
"From the tension optimization of the core wire and material purification of the wrap wire to the full packaging upgrade, every detail is crafted to deliver a purer and more stable playing experience. In the future, we will continue to focus on the musical instrument accessory industry, drive quality improvement through technological innovation, and help every musician unleash their musical inspiration."
The newly upgraded HSAP-1201 Phosphor Bronze Strings and HSAB-1201 (80/20) Brass Strings are now officially available through major musical instrument distributors nationwide and official online stores. Guitar enthusiasts are welcome to experience and purchase them.
