The Molten Voltage OZ is a footswitch controller that turns the Strymon TimeLine Delay into a full-featured looper. The TimeLine's looper has features that can only be reached through MIDI commands, and the OZ puts them under your feet: REVERSE, HALF-SPEED / DOUBLE-SPEED, UNDO, and REDO. Molten Voltage, the maker, describes the result as transforming the TimeLine into a "full-featured, high-fidelity, state-of-the-art LOOPER"1.
What the OZ does
The TimeLine's looper hides a set of functions behind MIDI commands that the pedal's own switches cannot reach. The OZ sends those commands from a footswitch, so a player can reverse a loop, drop to half speed or double speed, undo a take, or redo one, all without bending over the pedal. Molten Voltage states that the connection to the TimeLine is a one-cable MIDI OUT link with "no mods required"1.
The OZ also has a MIDI IN that merges and actively filters incoming MIDI data, which the maker says is for optimal TimeLine synchronization and performance1. That means other MIDI gear can feed into the OZ and pass through to the TimeLine without a separate splitter.
An optional version adds a Loop Level Jack for use with an external expression controller; on that version, the jack replaces the Loop Level knob1.

Power, size and build
The OZ runs on a standard "BOSS" type 9-volt DC, 2.1mm, tip negative power supply with a minimum of 200mA. The supply is sold separately, and the maker lists the current draw at approximately 120mA1.
The OZ is discontinued, and it has no battery option: it needs a standard "BOSS" type 9-volt DC, 2.1mm, 200mA min., tip negative power supply, sold separately1.
The enclosure measures 8.1 inches (206mm) wide by 4.8 inches (122mm) deep by 2.3 inches (59mm) tall. Molten Voltage describes the design as "bomb-proof" and calls the unit "Road-ready MIDI Machinery"1. Each OZ was hand built in Oregon, USA by Molten Voltage1.

Questions
Is the Molten Voltage OZ still made?
No. Molten Voltage lists the OZ as discontinued on its product page. It was a footswitch controller built to unlock the MIDI-only looper features of the Strymon TimeLine delay pedal, and it was hand built in Oregon, USA by Molten Voltage. Players looking for the unit today would need to find one secondhand, since the maker no longer offers it new.
Does the OZ run on a battery?
No. The OZ is powered by a standard BOSS type 9-volt DC, 2.1mm, tip negative power supply with a minimum of 200mA, and the maker notes that the power supply is sold separately. There is no battery option, so plan for a dedicated outlet or a pedalboard power supply output that can supply the needed current.
What does the OZ add to the Strymon TimeLine's looper?
The OZ unlocks the hidden looper features of the TimeLine that can only be accessed via MIDI commands, including REVERSE, HALF-SPEED / DOUBLE-SPEED, UNDO, and REDO. It connects to the TimeLine with a single-cable MIDI OUT connection requiring no modifications, and its MIDI IN merges and actively filters incoming MIDI data for optimal TimeLine synchronization and performance.
What is the OZ's current draw?
Molten Voltage lists the OZ's current draw at approximately 120mA. The pedal runs on a standard BOSS type 9-volt DC, 2.1mm, tip negative power supply rated for a minimum of 200mA, sold separately. Make sure whatever supply or power brick output you use can comfortably deliver that current.
Where is the OZ built?
The OZ was hand built in Oregon, USA by Molten Voltage. The maker describes it as bomb-proof, road-ready MIDI machinery, and the unit connects to the Strymon TimeLine with a single MIDI cable and no modifications to the pedal.
