Benson Stonk Box Fuzz: Modernizing Classic Fuzz with Precision

Introducing the Benson Stonk Box Fuzz, a remarkable pedal that brings the timeless 1960s fuzz sound into the modern era with unparalleled precision. Building upon the classic MK1 fuzz design, the Stonk Box retains the original FILTER and VOLUME controls while adding a TONE control and a TRIM control for expanded tonal possibilities. This pedal's advanced technology ensures consistent performance and eliminates the challenges of traditional transistor selection.

Automatic Thermal Bias Technology

At the heart of the Stonk Box Fuzz lies the revolutionary Automatic Thermal Bias Technology. This circuit gently warms the Germanium transistors, ensuring they operate at a preset point regardless of external temperature variations. When the LED transitions from amber to green, you'll know the transistors have reached their ideal bias point. This technology guarantees a consistent and reliable sound, making it suitable for a wide range of environmental conditions.

Versatile Controls for Tonal Exploration

The Stonk Box offers an array of controls to sculpt your ideal fuzz sound:

  • TRIM: A gain control located before the germanium transistors, providing a wide range of gain adjustment.
  • FILTER: Manipulates both gain and bias in the first gain stage, offering diverse fuzz and distortion textures.
  • TONE: Acts as a low-pass filter, balancing the bright attack and full body of the sound.
  • VOLUME: Provides increased output levels for pushing your amp's front end into exciting sonic territory.

Internal Trimmer and Power Supply

A cautionary note: The internal trimmer is factory-set to precision. Altering it will void the warranty, so it's advised not to tamper with it. The Stonk Box Fuzz operates exclusively on a 9vdc Boss-style center negative power supply, and no battery option is available. Please ensure not to exceed 9vdc to avoid potential damage to the pedal or power supply. The pedal draws minimal current and is compatible with most power supplies, although a current doubler cable or higher-rated power output may be necessary in some cases.

Explore the raw and distinctive world of fuzz with the Benson Stonk Box Fuzz. With its innovative technology and versatile controls, it's the perfect tool for both vintage enthusiasts and modern guitarists seeking to push their sonic boundaries.
