Seymour Duncan Diamondhead Distortion


Available from the 15th of December 2019

Seymour Duncan Diamondhead Distortion is a Multistage Distortion and Boost pedal that captures the tone and feel of a hot-rodded tube amp being pushed by a drive or boost pedal – the guitar sound that defined classic 70s and 80s Metal and Hard Rock.

It all starts with the drive – from breathy and raw medium gain sounds to screaming high-gain harmonics, Diamondhead is deep and three-dimensional, with clarity and touch response.

Three powerful active EQ controls maximize the potential of the gain section. A tightly defined bass control boosts and cuts at 80 Hz, with surgical precision – making the low end huge, but never muddy. A broader mid-range control set right at 800 Hz allows for massive scooped chunk, hyper aggressive modern attack, and everything in between. And the Treble control, set at 6 kHz, adds sizzle, cut, and attack.

The  SAT  Switch (based on the Seymour Duncan 805 Overdrive) adds a 24 dB pre-gain boost that tightens up the low end for more aggressive and defined attack. Subtly rolling off lows and highs, it allows the mid-range to cut through, creating chewy, harmonic saturation.

Independent from the Drive section, the Boost (activated with the left footswitch) offers 0 to 15 dB of available gain and can be used as a lead boost or to push an amp on the edge into overdrive. Try using it with a slightly dirty amp as the first gain stage and adding the Drive section for your highest gain sounds.
