The op-amp fuzz by Zander Circuitry.
A classic with a difference.
The legendary ‘Big M’ fuzz circuit launched a thousand innuendos and riff after earth-shaking riff. It’s also inspired countless reinterpretations over the years, all based on a pretty consistent circuit topology – with one exception. The classic 1970s op-amp model has a tone and feel that’s all its own, delivering crushing walls of gain and a sound that’s bigger than ‘big’. The Siva is our take on this very special circuit. And as you’d expect, we’ve added a few extra bells and whistles to bring it into the present day.
