Red Panda Tensor

Notify me when this product is available:

The Tensor™ gives you live reverse and tape stop effects, pitch shifting, time stretching and hold functions that you can combine in creative ways. Slow down, speed up and rewind in real time. Stretch or compress time with no pitch change. Loop, overdub, and randomly slice phrases up to 9.4 seconds (4.7 seconds in stereo).


Intelligent randomization adapts to the knob settings. The results range from occasional CD skips, stutters, and rhythmic repeats to random slicing and erratic pitch shifts. Both foot switches have momentary and latching modes to inject pitch jumps, glitches, or instantly rewind what you just played.


The Tensor™ is in a pedalboard-friendly enclosure with all jacks on top. All controls are immediately accessible with well-spaced knobs for live tweaking, and USB MIDI for recording and sequencing.
