ISP Technologies Michael Sweet Signature Empyrean

Isp Technologies · pedal

The ISP Technologies Empyrean is Michael Sweet's signature distortion, built around ISP's noise-reduction expertise: the pedal integrates their Decimator gating so that very high gain stays usable without a separate gate in the chain. Voiced for the tight, saturated modern-metal rhythm sound Sweet uses in Stryper, with the low end kept controlled rather than loose.
