Versatile fuzz factory for guitar or bass
The core of the Catalinbread Giygas is a Muff-style circuit with some tweaked component values to give it a distinctive voicing. Inside, you'll find a trim pot and a slider switch. The trim pot boosts or cuts 40Hz (cutting can help bassists clean up low-end mud and tighten your tone), while the slider shifts the center frequency for the mid boost and tilt EQ from 900Hz to 250Hz — this optimizes the tone controls for bass. Careful with the 40Hz control — if you boost it, then use the tilt EQ to boost bass, you're adding a ton of low-end content to your signal.
Tilt EQ for big tone shaping with little thought
Musicians and engineers alike have long appreciated the simple and effective nature of a tilt EQ like the one found on the Catalinbread Giygas fuzz pedal. Think of it like a beam balanced on a single point — bring up one end and the other lowers, and vice versa. You can achieve drastic tone changes without having to think about whether you're boosting or cutting individual frequencies too much, and always seems to sound musical regardless of where it's set.
