Seymour Duncan Diamondhead Multistage Distortion + Boost Pedal

Diamondhead Multistage Distortion + Boost Pedal 

• Powerful active EQ
• SAt switch adds 24db pre-gain
boost and tightens up the low end
• independent boost with zero to
15db of gain

Across genres and generations, the sound of a half stack pushed
hard with drive and boost has become a standard for rock tones.
No genre or era of players has been more heavily defined by
these iconic sounds than the classic metal and hard rock pioneers
of the late seventies and eighties. Think Judas Priest, RATT, Def
Leppard, Iron Maiden, Ozzy — their combination of tube heads
and drive pedals resulted in some of the most iconic guitar tones
of all time.
Diamondhead captures the power and versatility of that era-defining
rig in a package that will find a space on any pedalboard.
Whether you’re running it into a clean pedal platform amp or
into the frontend of an overdriven tube amp, the Diamondhead
provides the flexibility and tonal clarity to authentically capture
the sound that defined an era.
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 our 805 Overdrive) adds a 24dB pregain
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.
Diamondhead also shines as a pre-amp. By running it into the
effects return of your tube amp, or in front of our PowerStage
power amps you’ll be rewarded with a hot-rodded high gain amp
tone with body, bite, and character.
If you’ve gone through a pile of overdrives, distortions, and boost
pedals searching for that quintessential 80s metal or hard rock
tone and haven’t been satisfied, make Diamondhead the heart
of your rig — versatile enough to handle any covers set, precise
enough to surgically dial in your own tone — it captures the rock
‘n roll spirit of a high gain head pushed to the edge.
