I had a MicroQ and Rack Attack many years ago, made some beautiful stuff with both, really miss the Attack I must admit. The VST and IOS don’t do it for me though, I like having the brick in front of me! Sold both for reasons I can’t recall!
I bought a Q rack when it popped up but had to let it go as my circumstances changed a few years back.

I’ve got a Shadow XT but it’s fried, keep meaning to get it looked at but after speaking with a few engineers it’s not looking too promising! I kind of don’t want confirmation it’s dead so I’m too scared to send it off.
It’s in a coffin in my toy cupboard!
Think I’m going to have to check it out soon now the pain has subsided a little!
