In case you think I'm being a bit po faced in response to Jack's good natured humour, please allow me to expand.
I recently nearly broke my neck and an expensive instrument slipping over on a cable. They provide wonderful trip hazards and as such their elimination is one less disaster waiting to happen. I'm still in considerable pain nearly a month later.
Petrol being £1523.50 a half litre, any reduction in the weight my car carries saves me serious cash. Also saves my back.
Mains powered, pricey effects boards at the front of the stage (pub floor) are vulnerable to punter's/singer's feet and beer.
The amount of things that can go wrong on a conventional board with multiple patch cables and power cables and pedals is huge.
I don't need to bend over to tweak effects if they're on my phone, clamped to my stand. Saves my ancient back and doesn't strain my crappy eyesight.
Anyway all this is moot until I get it - it might be a piece of S H one tea, we'll see.
