The Vein-Tap.com Holy Ghost Fuzz and Boost Pedal is a two-sided pedal: a fuzz on one side and a clean boost on the other, each with its own footswitch. The fuzz side is built on the circuit of the Angel of Doom Fuzz pedal, and the boost side is the Little Horn Boost v2.0. Vein-Tap.com describes the result as "huge, heavy, army-stoppingly good tones" with "an independent boost loud enough to bring any audience to its knees"1.
Two independent sides
Both sides of the Holy Ghost are independent of each other, meaning you can engage one, the other, or both1:
- Fuzz only
- Boost only
- Fuzz into boost
Each channel has its own soft-touch relay footswitch, which Vein-Tap.com says allows for "smooth, silent, expensive-feeling switching"1.
The signal order is fixed: the boost side follows the fuzz side, so the boost pushes the fuzzed signal rather than feeding the fuzz1.
The fuzz side: an Angel of Doom, altered
The fuzz circuit is based on an original '78 IC Muff, the same basis as the Angel of Doom Fuzz pedal. For the Holy Ghost, Vein-Tap.com altered the negative feedback section of the second gain stage, which the maker says allows for "an added crunch to the tone"1.
The fuzz side carries a Limit control, which Vein-Tap.com describes as the most obvious addition: it reins in the input from especially hot pickups, tightening the sound and giving the fuzz a vintage character1.
The boost side: Little Horn Boost v2.0
The boost side is the Little Horn Boost v2.0 circuit, the same family as Vein-Tap.com's standalone Little Horn Clean Boost Pedal. It gives up to +24dB of clean boost, and Vein-Tap.com says it includes advanced power filtering, allowing for a much better gain to noise ratio1.
How it compares
Vein-Tap.com frames the Holy Ghost as the Angel of Doom's big brother: take the Angel of Doom, already a loud, thick and brutal fuzz, and make it louder with an independent boost added12. The Angel of Doom itself remains a fuzz-only pedal2.

Questions
What is the difference between the Holy Ghost and the Angel of Doom?
The Holy Ghost's fuzz side uses the Angel of Doom Fuzz circuit, but Vein-Tap.com altered the negative feedback section of the second gain stage for added crunch, and the boost side follows the fuzz. Vein-Tap.com describes the Holy Ghost as the Angel of Doom's big brother: the same loud, thick fuzz, made louder with an independent boost added.
Can I use the fuzz and boost of the Holy Ghost separately?
Yes. Both sides of the Holy Ghost are independent of each other, so you can engage the fuzz on its own, the boost on its own, or both together. Each side has its own soft-touch relay footswitch for smooth, silent switching.
Does the boost come before or after the fuzz?
The boost side follows the fuzz side of the Holy Ghost, so the boost pushes the fuzzed signal rather than feeding the fuzz.
How much clean boost does the Holy Ghost give?
The boost side, based on the Little Horn Boost v2.0, gives up to +24dB of clean boost, with advanced power filtering that Vein-Tap.com says allows for a much better gain to noise ratio.
What does the Limit control do?
The Limit control reins in the input from especially hot pickups, tightening the sound and giving the fuzz a vintage character, according to Vein-Tap.com.
What is the Holy Ghost's warranty?
The Holy Ghost is covered by the Vein-Tap.com Lifetime Guarantee.
