9V DC, center negative
Use a center-negative 9V DC power connection.

Independent shopping perspective
Twin Trem puts two analog tremolo voices in one pedal: Harmonic tremolo on the right and Optical tremolo on the left. Each side has its own Speed, Depth, and Volume controls, so you can set a restrained pulse on one side and a more pronounced movement on the other, then use them separately or together. The top-mounted jack layout also accommodates standard routing, an effect placed between the two tremolos, or separate stereo operation.
