Boveda is an expert when it comes to the effects of humidity and they offer a wide lineup of products to safeguard sensitive products. Extreme humidity fluctuations can wreak havoc on wooden musical instruments, causing them to expand, contract, warp, and go out of alignment. When incorporated into your regular routine, Boveda products automatically keep your guitar, bass, or stringed instrument at the ideal humidity level for months at a time. That means more time for you to play your instrument with consistency and less time spent in the shop for adjustments and repairs.
