enigsinds stroef om de kop te draainen maar als deze eenmaal gedraait super handig om ruimte te besparen op je pedal board

Bien pratique ce câble midi avec fiche rotative notamment pour un gain de place sur pedalboard. Le câble midi fait parfaitement son boulot, j'en ai déjà plusieurs et ils semblent tenir dans le temps. Donc à mon avis un très bon rapport qualité/prix.

Pour ce qui est de la fonction connexion électrique, tout va bien.
Cependant, attention à la dénomination : il n'y a que l'étrier de fixation du câble qui pivote, et pas la fiche en tant que telle.
Généralement, les pin sont horizontales (vers le haut ou le bas) ; il sera donc possible d’orienter le câble vers le haut ou le bas, mais pas en biais
