The Terra Firma is our beefiest distortion yet!

Voiced specifically for down tuned guitars, the Terra Firma is designed to replicate the sound of a certain famous amplifier popular in Doom & Stoner Rock circles, but in traditional Zander fashion, we had to add a few extras in…

The footswitchable gain control effectively gives you two pedals in one, letting you benefit from both the low and high gain tones the pedal has to offer.

Body, Shift and Tone control the low, mid and high end respectively, although they aren’t to be confused with a traditional tone stack as they work very interactively with one another, definitely one for the tweakers.

On top of all of this we’ve added in our signature 6 way clipping diode rotary switch, although on this pedal it works a little differently. Instead of being a very obvious set of hard-clipping diodes, in the Terra Firma, they are aiming to replicate various levels of amp ‘sag’ that come from pushing an amp to its limits. The effect of this will become more pronounced the louder the pedal is, to aid in this, an internal volume attenuator trimmer has been added that allows you to crank the level control even further.

Please do not try to power this pedal with anything other than 9v, doing so will cause your shiny new pedal to stop working permanently, and no one wants that.
