Boveda Large Instrument Humidity Starter Kit

The Boveda Large Instrument Humidity Starter Kit gives effortless, maintenance-free protection for full-sized acoustic and wooden instruments. Using Boveda's patented 2-way humidity control, the system automatically adds or removes moisture to maintain a stable 45-55% relative humidity, ideal for preserving tone, structural integrity, and playability without adding water or monitoring levels.

Suited to acoustic guitars, basses, cellos, banjos, guitarróns, and other large fretted or bowed instruments, this kit includes four Boveda 49% RH packets and two soft, double-pouch leakproof holders. The holders fit easily inside the case, keeping the instrument protected from cracking, warping, and tonal shifts caused by humidity fluctuations at home, on the road, or in the studio.
