Rockboard Flat XLR Cable 30 cm

I bough this, under the impression it was compatible with Rockboard pedalboards, however it does not fit through the slotted grid of the Rockboard Quad 4.1. As a result I can't use it.
Like all Rockboard products, this is a very high quality item, however it does not meet it's primary design function. I would send this back, however it would cost too much post back to Germany from the UK, so it'll just have to go in the spares bin as it's too short to be used as a regular XLR cable.
Ultimately, if you want to an XLR cable as part of your pedalboard, I would advise others to look elsewhere for a solution that works.
