In the video below, Tri Pedal Reviews takes a look at the new Pana-Trem by Porltand’s Mr Black – a Stereo Tremolo & harmonic vibrato with a bunch of trick up its sleeve, as company owner Jack Deville reveals in the second video streaming below.

The pedal features multiple panning settings, one preset storage capability (triggered by the footswitch on the right), and each parameter can be controlled through an expression pedal. More info at the bottom of this article.

A true-stereo harmonic-tremolo & panner featuring standard and panning modes of operation, fully independent left and right audio paths with an especially sweet & tonally rich pre-amp built right into each channel of the pedal.

A preset can be saved by pressing the Save button and activated/de-activated by pressing the Preset foot-switch.

Any standard expression pedal can be assigned to any, or all, of the control knobs on the fly, by simply connecting the expression pedal of choice to the EXP jack and turning the desired control all the way up to the blue dot.
