The Fuller Drive with Boost is a double pedal from Greuter Audio that puts two effects in one enclosure: the Fuller Drive overdrive and the company's Clean Boost. RockBoard's PedalPedia describes the combination as "a super dynamic overdrive in combination with a high headroom clean Boost", and the circuit is analog throughout1. It sits in the overlap between overdrive pedals and boost pedals.
What it does
The pedal houses two independent effects. The Fuller Drive side is an overdrive, and the Clean Boost side is a booster with high headroom, meaning it is designed to push level without adding much distortion of its own. Because both pedals work individually, each has its own switching: you can use the drive alone, the boost alone, or stack them, with the boost either pushing the front of the overdrive for more gain or lifting the whole signal after it1.
For a player, the appeal of a double pedal is board space and signal path. One enclosure covers two jobs that often travel together on a pedalboard, and the two circuits can be ordered and combined without extra patch cables or a separate boost unit.

Power and practical notes
The pedal runs on a 9V DC center negative supply and draws 13.5mA, a light load by pedal standards1.
The listing gives the power requirement as 9V DC, center negative. As with any pedal, use a supply that matches that polarity and voltage.

Questions
Can the two sides of the Fuller Drive with Boost be used separately?
Yes. Greuter Audio describes it as a double pedal housing the Fuller Drive overdrive and the Clean Boost, and states that both pedals work individually. That means you can switch the overdrive and the boost on their own, or use them together, without needing two separate enclosures on your board.
What powers the Fuller Drive with Boost?
The pedal runs on 9V DC with a center negative plug and draws 13.5mA of current, according to the product listing. That is a modest draw, but as with any pedal without a battery option stated, a standard isolated 9V DC supply is the way to power it.
