The Truetone TT-TVD Voltage Doubler is a compact power conversion accessory designed to expand the capabilities of standard pedal power supplies by automatically doubling voltage. It converts 9V DC outputs to 18V DC and 12V DC outputs to 24V DC, allowing compatible higher-voltage pedals to run from existing power sources without requiring dedicated adapters.
Simple to use and requiring no switches or manual configuration, the TT-TVD automatically detects and doubles the incoming voltage when connected inline between a power supply and pedal. This makes it an elegant solution for integrating 18V and 24V pedals into existing pedalboard power systems while reducing the need for additional power supplies.
Supporting pedals drawing up to 100mA, the Voltage Doubler is suitable for a wide range of compatible overdrives, boosts, compressors and other effects that benefit from higher voltage operation. It also provides a useful option for players exploring increased headroom and alternative pedal voicings available at higher voltages.
Designed to work seamlessly with Truetone 1 Spot products and other standard DC power supplies, the TT-TVD is a practical problem-solving tool for any guitarist wanting more flexibility from their pedalboard power setup.
