The Hyperdrive is a switchable voltage doubler. With an input of 9V you can feed an effect with a (filtered) 9V supply or double it to 18V. The LED indicator lights up when 18V is selected.
Works great to adjust an Overdrive from a more compressed sound to more head room. Also highly recommended in combination with the Nucleon Celeritas Compressor.
Be sure to use 25V or higher rated capacitors in builds that you want to incorporate this. The Hyperdrive is only suitable for effects running between 0V and 9V. Do not use it with split rail effects (with both a + and - supply voltage).
