Operational notes:

Note: The FreezeZone pedal operates at 1 amp positive ground. If your power supply is less than 1 amp or the individual outlet in your daisy chain is less than 1 amp, use the included 2 amp power adapter. The FreezeZone pedal can be used with less than one amp when the refrigeration unit is turned off..

There are three dials on the FreezeZone Pedal (Volume, Fuzz, and Bias). Use the Volume dial to adjust the volume with the volume level in true bypass mode. The Fuzz dial determines how much fuzz you want. Turning the Fuzz dial all the way up on the pedal and using the volume on your guitar to decrease the fuzz creates a cleaner brighter sound, than using the fuzz control by itself. The pedal cleans up well. Turning the Bias dial from noon to the left or right, increases or decreases the bias voltage. The transistors were biased with the Bias control at noon. Turning the Bias to the left creates more sustain and warmer tones, turning the Bias to the right produces a brighter spitty sound with hard velcro-like clipping, similar to heating up the transistor.

The thermostat has two temperature readings. The top temperature (in red) indicates the temperature of the germanium transistors, the bottom temperature (in blue) indicates you're target temperature. The thermostat comes preset to (50° Fahrenheit / 10° Celsius.) This is the temperature that the germanium transistors are biased to at the factory.

The two buttons on the thermostat (top) sets the target temperature and (bottom) changes the reading from Celsius to Fahrenheit. Press the top button once, the lower(blue) temperature starts flashing. While it is flashing, you can adjust the target temperature up or down by using the top and bottom button. Once you've reached your target temperature stop pressing the buttons and it will be set. When in use the top temperature in red will oscillate a few degrees above and below the target temperature (this is normal). For warm ambient temperatures leave the target temperature at (50° Fahrenheit /10° Celsius.), for hot weather set the target temperature at (46° Fahrenheit /8° Celsius.), for Extreme Hot temperatures set the target temperature to (40° Fahrenheit /4° Celsius.)

The switch on the left side of pedal, will turn the refrigeration unit on, along with the fan and the red led.

When the pedal is plugged in to the power and the refrigeration unit turned off, the temperature will rise up to 80° or higher depending on the ambient temperature. This is due to the 4.5 voltage supplied to the transistors.

Do not completely block the air vent on left side or the airport on the bottom end of pedal. This may prevent the pedal from achieving the target temperature. Leave at least a half inch clearance.

More about the FreezeZone external bias control:

The FreezeZone pedal allows you to explore different fuzz textures: Instantly switch between smooth, vintage fuzz and harsh, gated velcro effects without needing to open up the pedal.

Tailor the fuzz to your guitar: Compensate for differences between your guitar's pickups. For example, you can use a higher bias for lower-output single coils and a lower bias for higher-output humbuckers to get a consistent feel.

Clean up with your guitar's volume knob: Many fuzz pedals respond dynamically to your guitar's volume, but the bias setting can influence this interaction. You can find a bias setting that allows for more or less "cleanup" when rolling back your guitar's volume.
