The American Wizard Toneworks Ozma Overdrive is an overdrive pedal built around a deliberately small control set: two knobs and a three-position toggle switch. Pedal of the Day's review, published in November 2015, described it as "a simple, no-nonsense piece of gear" whose "stripped down, bare-bones gain is the name of the game here."1
Two knobs and a toggle
The main knobs are Volume and Gain. Pedal of the Day's reviewer, Mike B, wrote that "both of which boast high levels of their respective sonic duties," meaning the Volume knob has plenty of output level on tap and the Gain knob covers a wide range of gain shaping. The reviewer's overall verdict was that "2 control knobs and 1 toggle switch are all you really need to make your amp come alive, and your tone to vastly improve."1
The toggle switch is the pedal's voicing control. It offers three different voices for the overdriven sound, producing differing levels of output, tone, clarity and grit. In practice, that gives you three distinct flavors of gain from one pedal, set by flicking the switch rather than turning a knob.1
Power, bypass and connections
The Ozma runs from a 9V DC supply through a "Boss Style" power jack, the standard center negative connector found on most compact pedals, so it fits a normal pedalboard power setup. The pedal is true bypass, and its input and output are quality Neutrik brand 1/4 inch jacks. A bright blue LED shows when the effect is on.1

Questions
Is the Ozma Overdrive true bypass?
Yes. Pedal of the Day's review lists the Ozma Overdrive as true bypass, so when the pedal is switched off your guitar's signal passes through without the overdrive circuit loading it down. The pedal uses quality Neutrik brand 1/4 inch jacks for its input and output connections.
What power supply does the Ozma Overdrive need?
The Ozma Overdrive takes a 9V DC supply through a Boss style power jack, the same center negative barrel connector used by most compact pedals, so it will run from a standard pedalboard power supply. The review does not list a battery option or a current draw figure.
What does the voicing switch on the Ozma do?
The toggle switch offers three different voices for the overdriven sound. According to Pedal of the Day, the three positions produce differing levels of output, tone, clarity and grit, letting you shape the character of the gain without adding extra knobs to the pedal.
