Made famous by the Smashing Pumpkins on a string of classic records in the 1990’s, the op amp sound was not a roaring success at first.  Players in the 1970’s preferred the transistor based feel of the previous version, and could not get along with the crunchier, coarser, and sometimes sludgier distortion produced by the different components.

Times have changed, and these days, the op amp circuit is rightly looked on as a gateway to grungy brilliance.  The Siva from Zander Circuitry takes what makes it so iconic with additional sprinkling of clipping options to make it more flexible.  The Zander Circuitry Siva ramps things up in every department to put the sounds of the 70’s, 90’ and future at your feet.

EQ is the secret to getting the best out of a ‘Big M’ circuit.  Just like the Zander Circuitry transistor based version, the American Geek, the Zander Circuitry Siva provides two extra Shift controls that alter the capacitance of the tone stack for more control and the chance to get creative when dialling in specific sounds.

The Zander Circuitry Siva features a signature diode rotary switch, which switches between eight different clipping types for even more versatility.

  • Germanium: Smooth, sweet, and classically ‘amp like’
  • Silicon: Louder, brighter, and a little bit brittle
  • LED: Louder again, with less saturation and more punch
  • Asymmetrical germanium: A more aggressive version of germanium
  • Asymmetrical silicon: A more aggressive version of silicon
  • Asymmetrical LED: A more aggressive version of LED
  • Transistor/MOSFET: Similar to silicon, but sweeter and crunchier
  • No diodes: Loads of output and much less gain

For those times when there is no such thing as ‘too much gain’, the Zander Circuitry Siva Blast footswitch turns the drive all the way up and activates a second volume control for seamless transitions between low and high gain sounds.


  • Gain: Increase and decrease gain
  • Tone: EQ adjustment of the output signal
  • Shift 1: Tone shift high pass
  • Shift 2: Tone shift low pass
  • Level: Output volume
  • Blast: Output volume (in Blast mode)
  • Rotary: Clipping diode selector
