Red Panda Labs Tensor / Time Warp Pedal


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 4.8 seconds. 

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.

    This pedal is awesome. The ability to go forward and backward like a tape and overdub at the same time is pretty wicked. I had some of that functionality with my Echoplex, but this is pretty wild.
