Mission Engineering SP-1 Switching Expression Pedal
The Mission SP-1 is the worlds first professional quality switching expression pedal.
With two output jacks, one for the expression pedal and one for the switch, The SP-1 can be used with compatible devices to turn pedal driven effects such as a wah or vibrato on an off at the pedal itself.
The switch is operated by pushing down on the front with your foot in the same way as a traditional wah pedal. The SP-1 is compatible with most MIDI controllers and processors with two or more pedal jacks. The SP1-R option adds a polarity reversal capability. This is a mini toggle switch that reverses the polarity of the potentiometer for compatibility with devices that require a reversed polarity.
The SP-1 and SP1-R can be fitted with anoptional LEDto indicate latched and unlatched state. This can be used as an effect on/off indicator. The SP-1 is a passive device; no battery or external power is required unless the LED option is added. The LED is powered by an internal 9v battery (included), accessible via a base mounted battery door.
