Special Cranker

Controls, jacks, and indicators

Level

Use the Level control to adjust the output volume. Unity gain is between 10-12 o’clock, depending on which diodes are selected.

More

Use the More control to adjust the gain. This control changes the bias of the transistor, so you may hear a little noise when adjusting. Don’t worry; this is perfectly normal. At maximum gain, this device can achieve explosive overbiased tones depending on the output of your pickups.

Tone

Use the Tone control to roll off highs counterclockwise and boosts highs clockwise. A flat response can be found right around 3 o’clock.

Mode

Set the Mode diode selector to Ge (Germanium) on the left for a softer and more transparent tone. Set the Mode diode selector toSi (Silicon) on the right for a brighter and more modern edge.

Flexi-Switching

This device features Flexi-Switch® Technology! This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching.

Standard latching operation

Tap the footswitch once to activate the effect and then tap again to bypass.

Momentary operation

Hold the footswitch down for as long as you’d like to use the effect. Once you release the switch the effect will be bypassed.

Since the switching is relay-based, this pedal requires power to pass a signal.

Power supply

This device takes a standard 9-volt DC power supply with a 2.1-millimeter negative center barrel. We recommend using a pedal-specific, transformer-isolated wall-wart power supply or a power supply with multiple isolated outputs. Pedals will produce extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not always filter dirty power and may result in unwanted noise.

This device can be safely operated from 9 to 18 volts.
