New nylon strings naturally stretch during the first few days of use, which can cause them to go out of tune. This is completely normal. To help stabilize tuning consistency, gently stretch the strings daily for approximately three days after installation. This process helps the strings settle and maintain pitch more effectively.
Regular cleaning will keep your guitar in optimal condition:
Replace strings regularly to maintain optimal tone and playability. Use high-quality nylon classical guitar strings. When replacing, change one string at a time to maintain neck tension.
The HUSH C features a carbon-fiber-reinforced neck for enhanced stability. If you notice excessive neck relief (bowing) or back-bow, the truss rod may need adjustment. This is typically done with the provided hex wrench. It is recommended to have truss rod adjustments performed by a qualified guitar technician if you are unfamiliar with the process.

When not in use, store your HUSH C guitar in its gig bag to protect it from dust, humidity changes, and physical damage. Avoid exposing the guitar to extreme temperatures or direct sunlight.
