The Vein-Tap Holy Driver is an overdrive and boost pedal in one box, made by Vein-Tap.com. The maker describes it as "the only overdrive and boost pedal you will ever need," cramming what it calls two pro-level pedals into a single chassis1. The overdrive side carries the same circuit as the maker's Angel of Blues overdrive, while the boost side uses the Little Horn v2.0 clean boost circuit, giving you a drive stage and a 24dB gain stage that can be used separately or together1.
A two-sided overdrive and boost pedal
The Holy Driver is built as two pedals in one enclosure. Both the overdrive and boost sides are wired with true bypass, and each side is independent, so you can engage one, the other, or both at once1. That layout follows the pattern of Vein-Tap.com's other two-sided pedals, such as the Holy Ghost Fuzz and Boost Pedal, whose sides are likewise independent of each other2.
The overdrive side is packed with the same circuitry as the Angel of Blues, including that pedal's Modern / Classic overdrive profile switch and a diode clipping switch that selects symmetric or asymmetric clipping1. The boost side offers up to 24dB of what the maker calls "pure, clean gain," with a very high input impedance above 5MΩ, which Vein-Tap.com says keeps the sparkle in your pickups1.

The controls
The controls the maker documents for the Holy Driver are its switching options rather than a full knob list, and they are what set the pedal apart from a simple drive-plus-volume box.
| Control | What it does |
|---|---|
| Modern / Classic switch | Chooses between Classic and Modern overdrive tone profiles1 |
| Diode clipping switch | Selects symmetric or asymmetric clipping on the overdrive side1 |
| Pre / Post Boost switch | Places the boost before or after the overdrive circuit1 |
The Pre / Post Boost switch is the pedal's signature feature. As Vein-Tap.com's Ben explains in the maker's overdrive-and-boost buying guide, the Holy Driver "has a Pre / Post switch in the pedal itself which lets you choose whether the boost cascades into the overdrive, or vice versa"3. In the Pre position the boost feeds the overdrive circuit, driving it harder; in the Post position the boost sits after the overdrive, lifting the level of the driven signal.
Circuits from the Angel of Blues and Little Horn v2.0
The Holy Driver is essentially a pairing of two existing Vein-Tap.com circuits. The overdrive side carries the same overdrive circuitry as the Angel of Blues, as the maker describes it1. The boost side uses the Little Horn v2.0 boost1.
The same Little Horn boost circuit appears elsewhere in the maker's range: Vein-Tap.com says the boost section of the Holy Roar distortion and boost pedal is based on its Little Horn, with its distortion side based on the Angel of Rock distortion pedal4.
Classic and Modern modes
The overdrive side's profile switch offers two voices, and the maker describes the difference in plain terms1:
- Classic: a mellow, smooth overdrive suited to blues or gentler rock tones, with a boost in the mid frequencies1
- Modern: a flatter, more aggressive, bass-heavy tone aimed at modern rock1
The clipping switch adds a second layer of choice, letting you pick between symmetric and asymmetric diode clipping, the same option found on the Angel of Blues1.
Where it is made, and a note on the name
The Holy Driver is hand-crafted in the UK by Vein-Tap.com and covered by the maker's Lifetime Guarantee1. Vein-Tap.com states that its pedals are handmade in the UK and guaranteed to last a lifetime.
Don't confuse this pedal with the Egnater Holy Driver, a different overdrive pedal aimed at metal guitarists that Guitar World reported on in 2012. Despite the shared name, it is a separate product from a different maker5.

Questions
Is the Vein-Tap Holy Driver true bypass?
Yes. Vein-Tap.com wires both the overdrive and boost sides with true bypass, and each side is independent, so the circuitry stays completely out of the signal path when a side is switched off. You can engage the overdrive, the boost, or both at once.
Can the Holy Driver's boost go before or after the overdrive?
Yes. A Pre / Post Boost switch on the pedal lets you choose the order. In the Pre position the boost feeds into the overdrive circuit, pushing it harder; in the Post position the boost comes after the overdrive, raising the level of the driven signal.
What is the difference between the Classic and Modern modes on the Holy Driver?
Classic is a mellow, smooth overdrive voiced for blues and gentler rock, with a boost in the mid frequencies. Modern is a flatter, more aggressive, bass-heavy profile aimed at modern rock. A switch on the overdrive side selects between the two.
How much clean gain does the Holy Driver's boost add?
Up to 24dB of clean gain. The boost side uses the Little Horn v2.0 circuit, which adds advanced power filtering for a better gain-to-noise ratio, and has an input impedance above 5MΩ to preserve the character of your pickups.
Where is the Vein-Tap Holy Driver made?
It is hand-crafted in the UK by Vein-Tap.com, and like the rest of the maker's pedals it is covered by the Vein-Tap.com Lifetime Guarantee.
