The "Siamese Dream" Fuzz, On Steroids!

The Zander Circuitry Siva takes the late '70s IC/op-amp Big Muff - as used so effectively by The Smashing Pumpkins - and drags it kicking and screaming into the 21st century.

The op-amp Muff circuit is perfect for grunge, but can do so much more: it's crunchy, sludgy and is packed full of crushing gain.

Siva EQ

Key to getting a great tone is the EQ, and the Siva features a super-tweakable EQ section. Two Shift controls alter the capacitor values in the tone stack, adjusting the filter sweep and cut-off. These controls interact with the Tone control to enable you to dial in the perfect sound.

What's new?

This latest version of the Zander Circuitry Siva features a more compact footprint, beautiful knurled steel controls, and an upgrade from six to eight options on the signature clipping selector:

  • 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.

The pedal features two footswitches, the second of which gives you access to the Blast function - a second channel with an independent volume control and the gain set to maximum. The switches support both momentary and latching switching, meaning that you can temporarily engage a channel by holding your foot down on the relevant switch then releasing it when you're done.
