D'Addario XPND Pedalboard Mic Stand, BlackSay goodbye to clunky stage positioning with the D'Addario XPND Pedalboard Mic Stand. Most performing musicians have encountered the hardship of positioning a microphone stand just right so that pedals are still in front and accessible. The XPND clamps directly onto most 2 row, rail style pedalboards to tighten up the stage and to put the focus back on performing.
