Power and Safety
This pedal requires a 9v DC negative center tip power supply (standard pedalboard power) to operate. Do NOT operate at higher voltages, with positive center, or AC current. It is highly recommended that you use an isolated power supply rather than daisy-chaining, as it will help keep the noise floor down.
This is an electrical device. Take care to keep dry and avoid liquids as they may be a shock hazard or damage the pedal.
Controls
LEVEL: set the overall output volume of the pedal
GAIN: set the amount of gain. As you turn this knob, the pedal will also get louder.
TONE: EQ control. Unlike many tone controls, this affects both top and bottom frequencies simultaneously. Increasing treble also cuts bass, and vice-versa. Middle is most balanced.
VOICE: this control is interactive with the Tone control. Down provides a scooped mids effect, Up produces a noticeably strong boost to the mids, and will dramatically affect the shaping effect of the Tone control. It will likely also get a bit louder when you push it up.
CLIP: this switch offers multiple compression settings. As you change its setting you will notice more drive saturation (effect is interactive with the gain knob). NOTE: stronger clip settings will result in some volume loss, due to the way in which diodes work; simply raise the LEVEL control to compensate.
Internal
LED BRIGHT: Many PHD Pedals have an internal trimmer control that allows some adjustment to LED brightness. This can be found on the PCB attached to the footswitch. Care must be taken while making adjustments so as not to damage internal components. If adjustments are made while the power is on, be extra careful not to create electrical shorts.
