The Mosky MARKMAN is a hand-built overdrive pedal that Mosky describes as based on the Klon Centaur circuit1. The Klon Centaur, made by Klon LLC, is a hard-clipping overdrive that has drawn enough attention over the years to spawn a whole field of copies and Klon-style pedals234. The MARKMAN is Mosky's take on that circuit, offered as an overdrive/distortion pedal in the company's hand-built range1.
What it is
Mosky's product page lists the MARKMAN as a hand-built effect pedal in the M-SERIES range, with the circuit described as "Based on KLON CENTAUR circuit"1. The Klon Centaur it draws from is an overdrive pedal, and one that MusicRadar's Rob Laing and builder Brian Wampler describe as technically a hard-clipping overdrive, meaning the gain stage clips the signal using hard-clipping diodes rather than a softer clipping arrangement2.
For a player, that places the MARKMAN among the many Klon-style overdrives on the market: a circuit with a GAIN control for the drive amount, a TREBLE control for tone shaping, and an OUTPUT control for level1. Mosky does not publish sound descriptions beyond the circuit basis, so what it does to a player's tone is best understood through what the Klon circuit is: a hard-clipping overdrive design2.
Controls
| Control | What it does |
|---|---|
| GAIN | Sets the amount of overdrive1 |
| TREBLE | Tone control for treble content1 |
| OUTPUT | Sets the pedal's output level1 |
Mosky lists the three controls as OUTPUT, TREBLE and GAIN1. There is no published detail from Mosky on the internal operation of each knob beyond their names, so the table reflects the control layout as given on the product page1.
Power and size
The MARKMAN runs on a 9V DC supply and draws 100mA, with the power jack wired center negative1. That polarity matches the standard used across most pedalboard power supplies and daisy chains, so a typical 9V center-negative adapter is the right match. The 100mA draw is worth noting for players sharing a supply output across several pedals, since some daisy-chain outputs are rated lower than 100mA.
Mosky specifies "Power Supply : DC9V 100mA -center is negative"1. A supply rated below 100mA may not run the pedal reliably.
The enclosure measures 11.5 by 6.5 by 5 cm, length by width by height, and weighs 300g1. That is a compact box by the standards of hand-built pedals, and the 300g weight keeps it light on a pedalboard.
Where it sits among Mosky's overdrives
Mosky's hand-built range includes several overdrive designs alongside the MARKMAN, each based on a different well-known circuit. Players comparing Klon-style options within the brand can look at the MARKMAN against the rest of the overdrive pedal lineup, including the Mosky Golden Horse, the MOSKY Green Drive Overdrive, the Mosky Mini Screamer Overdrive, the Mosky Mini TM Overdrive, the MOSKY MM Silver Overdrive, the Mosky Obsessive Overdrive, the Mosky Compass Drive, the Mosky MM Overdrive, the Mosky ULTIMATE Overdrive, the Mosky Green Screamer, the Mosky Hand-Wired Ultimate Drive, the Mosky BB Preamp and the MOSKY B-Box Preamp. The MARKMAN is the one Mosky identifies as Klon Centaur based1.
Questions
Is the Mosky MARKMAN a Klon Centaur clone?
Mosky's own product page describes the MARKMAN as based on the Klon Centaur circuit, so it is a Klon-style overdrive rather than an original design. The Klon Centaur itself is a hard-clipping overdrive pedal, originally made by Klon LLC. The MARKMAN carries three controls, OUTPUT, TREBLE and GAIN, in a compact hand-built enclosure.
What power supply does the Mosky MARKMAN need?
Mosky specifies a 9V DC supply capable of 100mA. The pedal draws up to 100mA, so a standard 9V adapter with enough current headroom will run it. Because the power jack is center negative, it follows the usual pedalboard convention and works with typical daisy-chain and isolated supplies rated for the draw.
What is the polarity of the Mosky MARKMAN power jack?
The MARKMAN's power jack is center negative, according to Mosky's product page. That matches the polarity used by most guitar pedals, so a standard center-negative 9V DC adapter is the right match. Check the polarity marking on any supply before plugging in, since a center-positive adapter of the wrong voltage can damage a pedal.
How big is the Mosky MARKMAN?
Mosky lists the MARKMAN at 11.5 by 6.5 by 5 cm, length by width by height, with a weight of 300g. That is a compact footprint by full-size pedal standards, so it fits a crowded pedalboard without much trouble, and the 300g weight keeps it light enough for a pedalboard bag or a small board.
Which Mosky range is the MARKMAN part of?
Mosky lists the MARKMAN under its M-SERIES of hand-built effect pedals. The M-SERIES covers Mosky's hand-built pedal range, and the MARKMAN sits in it as the company's Klon Centaur-based overdrive, alongside the brand's other overdrive and distortion designs.
