Pulse is a miniature IR (impulse response) loader pedal, that can apply a specific tonal profile to the input signal. Speaker cabinets typically change the tone of a guitar or bass guitar in a musical way, which is often collected using a microphone for sending to a mixing console for recording or sound reinforcement. Connecting the signal to a mixer before the speaker usually produces a sterile and harsh sound, which is where the Pulse pedal comes in. This pedal can mimic the speaker cabinet and microphone, meaning that the guitar signal can be taken straight from the preamp section and injected into a channel on the mixer. Another use for IR loaders is to mimic the response of an acoustic guitar, making an electric guitar sound more like an acoustic or an electro-acoustic guitar sound more natural. Pulse has modes for guitar cab, bass cab or acoustic guitar with 8 selectable types of each, adjusted by Level and Space controls. A 3.5mm headphone output means that this pedal can also be used for silent practice and an inbuilt audio to USB interface means that it can be used as the front end for a PC or Mac computer recording setup. Pulse is an invaluable guitarists and bass players multi-tool for practice, live and recording duties.
