The Bowman Overdrive is a hand-built overdrive from Bowman Audio Endeavors, a New Jersey builder run by guitarist James Bowman. It is a recreation of the Klon Centaur circuit: Delicious Audio calls it "B.A.E.'s take on the Centaur, Transparent Overdrive Circuit" and "a faithful recreation using quality components," and added it to the site's Klon Clones Shopping Guide in August 20211.
What sets it apart from other Centaur-inspired pedals is its lineage. Pedal of the Day notes that "The Bowman is a direct descendent of an original Klon pedal, James' personal one, in fact," meaning the design traces back to a pedal James Bowman owns and plays rather than to a schematic alone2.
Where the circuit comes from
The Klon Centaur, designed by Bill Finnegan, is the pedal that effectively defined the transparent overdrive idea: Guitar World describes it as "this transparent overdrive produced by Bill Finnegan [that] took the world by storm"34. GuitarPCB's technical analysis explains the original design goal as improving on the TubeScreamer's transient response and midrange-bass frequencies to create a big, open sound with a hint of tube clipping5. Gearnews' history of the Centaur argues it was no simple Tube Screamer modification but "a highly sophisticated piece of engineering" that birthed the transparent overdrive category6.
The Bowman follows that template. Like the Centaur, it is aimed at players who want gain that leaves their amp's core tone recognizably intact, whether pushing an already-driven amp or adding a touch of grit to a clean one127.
Controls and use
The control set is the familiar three-knob Klon layout:
| Control | What it does |
|---|---|
| Gain | Sets the amount of drive |
| Tone | Shapes the treble character |
| Output | Sets the pedal's level |
Pedal of the Day sums it up as "Gain, Tone and Output are the parameters you know and love," with Oxblood Davies style knobs on the facia12.
Beyond overdrive duties, the pedal doubles as a boost. EarthQuaker Devices' Patrick Benson, writing in a pedalboard guide, says: "These sound best used as an overdrive but do a clean boost very well."7 That makes it a candidate for players comparing it with dedicated boost pedals: with the gain low and the output up, it can push an amp or lift other pedals without changing the basic tone.
What reviewers said
Pedal of the Day's verdict was warm: "the Bowman Overdrive crushes amps and delivers the goods, as you'd expect," adding that "it sounds fantastic, if we do say so"2. Delicious Audio's endorsement is simpler: a faithful recreation using quality components1.
"I will also add that this is hand-built by a great guitar player and an even better human"
Questions
Is the Bowman Overdrive a Klon clone?
Yes. Delicious Audio describes it as B.A.E.'s take on the Centaur, a faithful recreation of the Klon circuit using quality components, and lists it in its Klon Clones Shopping Guide. Pedal of the Day goes further, noting that the Bowman is a direct descendent of an original Klon pedal, in fact builder James Bowman's personal one.
Can the Bowman Overdrive be used as a clean boost?
Yes. EarthQuaker Devices' Patrick Benson writes that these sound best used as an overdrive but do a clean boost very well. Pedal of the Day likewise frames it as an overdrive and boost pedal, so it works at both ends of the gain range.
What controls does the Bowman Overdrive have?
Gain, Tone and Output, the same three control layout the Klon Centaur made familiar. Pedal of the Day calls them the parameters you know and love. The knobs themselves are Oxblood Davies style, according to Delicious Audio.
Who makes the Bowman Overdrive?
Bowman Audio Endeavors, a New Jersey builder run by James Bowman. Pedal of the Day notes that the pedal was made by an incredible guitarist, and EarthQuaker Devices describes it as hand-built by a great guitar player and an even better human.
Is the Bowman Overdrive hand-built?
Yes. Delicious Audio describes it as a faithful recreation using quality components, and EarthQuaker Devices' Patrick Benson adds that it is hand-built. The enclosure is a UV printed, silver powder coated Gørva Design S90 enclosure.
