Pulse Technology FPT-37 Harmonizer Pitch Shifter Guitar Effect Pedal 2 Octaves The Pulse PT-37 has a straightforward interface which makes it easy to choose the relevant settings required for your desired sound output. It features a Dry and a Wet set option. Dry controls the volume of the original signal sound, whereby Wet controls the volume of the wet signal. The Pulse Harmonizer Pedal really extends the frequency range of sound produced by the electric guitar. Using the toggle switch, a selection of up tuning, down tuning or de-tuning can be selected to introduce some serious depth and warped undertones to the guitar. The Harmonizer works by creating a duplicate layer of the original sound which is then controlled by the Range knob that determines the actual frequency range of the altered layer. It can vary the duplicate sound by up to 2 octaves, creating either a mush brighter ( in UP mode) or much deeper ( Down mode) tone. Adjusting the depth and wet knobs can place the duplicated layer as the prominent or the underlying tone. The Pulse PT-37 Harmonizer also features a 11 set dial, and each of these options offer a unique shift in pitch, as well as the choice to go up or down by not just one, but two octaves. The foot-switch of the PT-37 Pitch Shifter pedal which is constructed using advanced capacitor technology has a few functions, it not only engages the pedal, but once switched on if you press down once this allows you to switch between the original sound and the effect; press down twice and this switches between the fixed mode and the original. If you?re creating some cool sound layers then you can store the parameters simply by holding down on the foot-switch. Compact / Miniature Case Size Advances in circuitry design have made is possible for guitar effect pedals to be built in compact enclosures that literally fit in the palm of the hand. The mini design allows more pedals to fit on a pedal-board and helps reduce the overall weight, making them an ideal solution for the traveling guitarist. Store Function with Soft Touch Switching Pulse digital effects pedals feature a built-in store function, to quickly save and recall any configuration of effects you create. Hold down the soft touch switch to save a setting, and double tap the switch to recall. Green and red LED indicator lights determine the currently selected channel, and flash to clearly show when a setting is saved. Recall presets even after the pedal is switched off an unplugged. True Bypass Circuitry The compact inner circuitry is designed with a 3PDT true bypass switch ensuring an unaltered tone when the pedal is not engaged. A true bypass switch has the ability perform a true bypass of the internal hardware circuit of the pedal, meaning the signal goes straight from the IN to the OUT.
