The Eureka! is a versatile silicon fuzz-distortion that combines singing, dynamic midrange with the weight, grit and sustain of classic Muff-style circuits. Its proprietary architecture stays responsive and distinctive across different guitars, effects and amplifiers, making it an unusually adaptable fuzz for both rhythm and lead work.

A three-position bass switch moves from a focused core voice to progressively heavier low end, helping match single coils, humbuckers and solo sounds. At the maximum bass setting, a strong input signal can push the circuit into a gated, spluttering response. From searing mid-rich leads to huge, snarling riffs, Eureka! keeps its own unmistakable voice
