Real-Time Climate Control

Because fine guitars are most vulnerable to low humidity, active humidification is a standard environmental feature of our cabinetry. While exposure to occasional periods of high humidity can cause temporary changes, nothing robs the life and tonal quality of fine guitar faster and more delirious than long winter heating cycles and dry arid summer weather.

Those that own quality instruments know that to ensure their playability and superior tone, they must closely monitor the humidity their instruments are exposed to. It is to that end, that our cabinets are best suited. The digital electronic humidification system built into each cabinet, puts an end to the continual monitoring and worry about your instruments. Divine Design's humidification system actually monitors the relative humidity inside the cabinet, and makes necessary changes to the humidity level, according to parameters set by the user - something that passive, or even case humidification can never accomplish.


Attempts by individuals, as well as those by other cabinet companies to provide humidification, though somewhat effective, either require prolonged periods of time to reach given humidity levels, involve a stout maintenance routine, or have water reservoirs that require frequent attention.

Passive humidification generally involves the placement of water laden trays, packets or beads intended to add humidity to the air via evaporation. They are both inexpensive and easy to maintain. However, their effectiveness is often limited by a lack of any means to adjust and maintain target humidity levels with any accuracy.

Wick type humidification systems, similar to most room size humidifiers, are the most common type presently employed in guitar cabinets. They function by circulating air in the cabinet across or through a wet or saturated surface. While far more effective and reliable than passive humidification, the duty cycle is often long, the use of a saturated wick is prone to the buildup of harmful bacteria, and are often tedious to maintain.

Silently, the system functions to maintain the humidity envelope the user sets. As a general rule, each humidification cycle is completed in under two minutes, and in rooms that host an ambient relative humidity of 20 percent, the system will cycle approximately 2 times per hour.

Under occasionally high relative humidity conditions, such as those that oscillate during summer months, the integrity of cabinet's tight solid wood construction moderates exterior humidity levels to (depending upon the control setting) between 45 and 55 percent relative humidity.

Humidity and temperature within the cabinet are continuously monitored. The resulting relative humidity is continually reported by the programmable controller located out of immediate sight, but easily accessible either in the top of the cabinet (Master Series), or in the lower portion, just behind the glass doors (Player Series). The programmable controller permits setting the humidity to any desired envelope. Once set, its function is entirely automatic.

So How Does It Work?

Our patent pending system functions by monitoring the relative humidity in the cabinet. When the level drops below the selected value, an ultrasonic unit located inside the tank begins atomizing the water, which mixes with air drawn from the front cabinet vent, through the tank. As the air moves through the tank, and its humidity level increases, it is drawn into a manifold that runs horizontally across the bottom unit and is forced out at an equal rate through the two vents located toward the rear of the upper cabinet on each side. This 'loaded' air then circulates through the upper cabinet and is again drawn through the vent near the front, where the entire cycle is repeated until the level of humidity in the upper cabinet reaches the upper limit of the preset value. At that point the system shuts off until the air within the cabinet once again drops below the lower limit of the selected value, when it once again starts to repeat the cycle.
