Q: What is the Truetone 1 SPOT Voltage Doubler and what does it do?

The Truetone 1 SPOT Voltage Doubler cable lets you power pedals requiring 18V or 24V from a single 9V or 12V output, respectively, on your power supply. It has a built-in step-up transformer that automatically converts a 9V DC input to 18V DC, or a 12V DC input to 24V DC. This is perfect for effects pedals that operate at a higher voltage, allowing you to expand the capabilities of your existing power supply.

Q: How do I connect the 1 SPOT Voltage Doubler to my pedals and power supply?

To use the Voltage Doubler, plug the input end into a standard 9V DC or 12V DC output from your power supply, such as a Truetone 1 SPOT. Then, connect the output end of the cable into the higher voltage input jack (18V or 24V) of your compatible effects pedal. Always ensure your pedal is designed to accept either 18V or 24V, depending on your input voltage, before connecting to prevent damage.

Q: Which pedals are compatible with the Truetone 1 SPOT Voltage Doubler?

This cable is designed for effects pedals that specifically require either 18V DC or 24V DC power and use a standard barrel plug. Many overdrive, delay, and modulation pedals can operate at these higher voltages for increased headroom or different tonal characteristics. Always check your pedal's manufacturer specifications for its exact voltage and current requirements to ensure compatibility and safe operation.

This thing is a life saver and wallet saver. If your power supply doesn't have a 18v or you daisy chain 9v power supplies you definitely want this. It's about the same price you'd pay for an independent adapter, and you're saving big instead of buying a power supply box. I no longer have to keep buying 9v batteries just to keep jamming on my EVH Flanger. I cannot be more happier with this.

I've got 10 pedals on my board and only one of them does 18v, and it really is one of those pedals that just sounds better at 18v. I've got a daisy chain set up (sacrilege I know, but it works for me) and had one separate 18v power wart mucking the whole thing up. Not knowing the expense of the electronics in the TVD 1 SPOT, my gut reaction is that this is far too expensive for what it does, seems like you could buy a whole separate power wart for the same price or less. And yet I've got to give it 5 stars because after plunking down my money I tucked this in and never had to deal with the separate power (or a large crazy multi-power unit) again. It's not exciting but it does what it's supposed to and the convenience is worth the price.

I've been running my old Big-Box Deluxe Memory Man from a 12v output on my One Spot Pro CS12, using one of these to bring it up to 24v, for the past 5 or so years without any issues. No wall-wart needed!

I purchased this to go along with my One Spot power supply allowing me to provide up to 24v power to my Hudson Electronics Broadcast pedal. Works great.

Headroom galore. Works flawlessly
