As i wanted to build a new bass FX board as compact as possible for my Eventide Pitchfactor, Timefactor & TC Electronic Nova System, i used 3 pairs of these to splice them into 3 single cables, all with angled plugs at each end.
These have got to be the most compact MIDI plugs i've ever seen AND last but not least : the pins have the right orientation for the pedals mentioned above
The 12mm deep plug head really allows mounting the pedals VERY close together
