    About the ZANDER CIRCUITRY Terra Firma


    The Zander Circuitry Terra Firma is a power-amp distortion pedal which emulates the ripping, gnarly sounds of a cranked Sunn Model T amp.

    Specifically voiced for down-tuned guitars, the Terra Firma is based around the LM386 power amp chip (as used to great effect in the EarthQuaker Devices Acapulco Gold), combining analogue character with searing output volume.

    Terra Firma Controls

    • Gain: Adjusts the gain level.
    • Tone: Affects the high end filtering
    • Shift: Adjusts the specific frequency range the Tone control operates in.
    • Body: adjusts the bass/ low-mids filtering.
    • Blast: Controls the volume when the Blast footswitch is activated.
    • Level: Output volume. 

    The Blast footswitch maxes out the gain and activates the Blast volume control. It can be operated in either momentary or latching modes.

    What's new in this version of the Terra Firma?

    This latest version of the Zander Circuitry Terra Firma features a more compact footprint, knurled steel controls, and eight rather than six clipping options:

    • Germanium: A smooth, sweet sounding form of clipping, very ‘amp-like’ in its response.
    • Silicon: Louder, brighter and more aggressive sounding.
    • LED: Even louder, less saturated but very punchy.
    • Asymmetrical Germanium: A more aggressive germanium sound.
    • Asymmetrical Silicon: Beefing up the aggression of the silicon sound.
    • Asymmetrical LED: A more aggressive version of the LED sound.
    • MOSFET: Similar to the silicon setting but a bit sweeter, crunchier and a touch more saturated.
    • No diodes: Loads of output but not much gain.
