Pros
Solid, good quality
I've been looking for bass pedals on ebay for about a year, but they all go for silly money. This is great purchase to be the basis for playing midi keys with your feet. The build quality is very good, solid and I'm confident they will last. I didn't buy the metal plate, but regret not doing so, as the work to cut out a panel around the elliptical buttons is off-putting. I'm very happy with my purchase.
Cons
Short on useful details
There are some shortcomings. The instructions are rather opaque. I managed to plug the midi converter plug in upside down and spent about an hour trying to work out where I'd gone wrong. The supplied power supply is an EU 2-pin of a design that doesn't readily convert or fit converter plugs. So you really should replace it. The midi sockets need to be mounted through a surface, but are already soldered in place, so you'll need to desolder to do that. And finally the power socket on the converter board is mounted in such a way that you'll need to fix this at the very top edge of your case. A simple set of case dimensions would be helpful, and you have to attach a couple of long feet for the pedals to operate and once again it would help to know what depth of wood you need.
But I'm still a fan. Though I'd buy the metal plate if I was buying again.
