Unfortunately this design seems to be the counter solution to all of the issues that a pedalboard has proven to solve, at the expense of the impression of flexibility.
Let's begin with a well thought out homespun pedalboard. There is a rigid, lightweight frame, some method of attaching pedals securely, again usually lightweight and simple. The whole point of this is to prevent cable movement and the need to setup & tear down. Next we add a form of cabling for audio and usually a power solution with usolated power lines, all for the purpose of reducing noise and again having a reliable, portable setup. Simple.
Here's a list:
1) Magnets on a pedalboard create two issues; sliding and magnetic interference. Movement reduces cable reliability, adds stress. Movement and noise are bad.
2) Power isolation is not possible. Noise is bad.
3) Ferrous metal to allow magnets to adhere usually results in oxidzing, rust etc. Given that this is how power is also applied, age means more chance for noise and reduced power transmission. More noise and reduced reliability is bad.
4) Weight with additional plates to attach to pedals. But wait; the original method to attach pedals to plates is also still there? Now we are adding cost and redundancy, along with an added point of possible failure!
5) Someone said $1k to set this up? If someone started new using the current standard, $1k gets you some of the best equipment out there. Excellenr power supplies, rigid boards with good cases etc. Price is really high...
This gives you a board with a daisy chain and a solution that rivals loose zip ties holding pedals to a heavy board. One hard step and you knock all the pedals off your board and will be lucky if nothing breaks. Sorry I'm so negative about this design, but it's just wrong, stay away.
