Seymour Duncan Diamondhead Distortion+ Boost Pedal

The legendary guitar tones that defined classic metal and hard rock didn't happen by accident – they came from the perfect marriage of tube heads and drive pedals that created some of music's most iconic sounds. Diamondhead captures the power and versatility of that era-defining rig used by pioneers like Judas Priest, RATT, Def Leppard, Iron Maiden, and Black Sabbath, packaging it into a pedal that will find its place on any pedalboard.

At its core, Diamondhead offers everything from breathy, raw medium gain sounds to screaming high-gain harmonics with deep, three-dimensional character and exceptional clarity. Three powerful active EQ controls maximise the potential of the gain section: a tightly defined bass control that boosts and cuts at 80 Hz with surgical precision, making the low end huge but never muddy; a broader mid-range control set at 800 Hz for massive scooped chunk or hyper aggressive modern attack; and a treble control at 6 kHz that adds sizzle, cut, and attack.

The SAT Switch (based on the Seymour Duncan 805 Overdrive) adds a 24dB pre-gain boost that tightens up the low end for more aggressive and defined attack, subtly rolling off lows and highs to let the mid-range cut through with chewy, harmonic saturation. Independent from the Drive section, the Boost 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. This versatility makes it perfect for handling any covers set while being precise enough to surgically dial in your own signature tone.
