Boveda Music Large Starter Kit: 49% RH Humidity Control for Guitars

Automatic two-way humidity control (49% RH) stabilizes wooden instruments and accessories in cases, reducing warping and fret issues.

Includes two fabric holders and three humidity packs, designed for large guitars, basses, cellos, and large woodwinds.

Mess-free operation with pre-measured, saltwater-based packs that require no liquids or additives; replace every ~3 months.

Broad instrument compatibility for guitars (acoustic, hollow-body, nylon/string), bass, cello, and some woodwinds when stored properly.

Trusted Boveda lineage with decades of RH control experience, offering reliable protection for valuable instruments.

Compact starter kit tailored for large instruments; simple placement in cases to maintain consistent humidity.

Durable packaging and reusable holders support long-term storage across multiple seasons.

Price sensitivity: reviewers note the kit is relatively expensive compared to simple sponge or rider-pack methods.

Fabric holder quality can vary; there are reports of tearing or misplacement which may drop packs into sound holes.

Limited case-fit compatibility: in very tight or uniquely shaped cases, two holders may clash with hardware or access.

Replacement cadence (every 3 months) requires ongoing purchasing and planning, which may deter casual users.

Not all instruments or case configurations are explicitly covered; verify fit for your specific setup before purchasing.
