The Boveda Large Instrument Humidity Starter Kit offers effortless, maintenance-free protection for your full-sized acoustic and wooden instruments. Using Boveda’s patented 2-way humidity control, this system automatically adds or removes moisture to maintain a stable 45–55% relative humidity—ideal for preserving tone, structural integrity, and playability. Unlike traditional humidifiers, there's no need to add water or monitor levels. Just set it and forget it.
