Hi, I'm on the Isle of Wight but 'ANG ON! ...I've just dug it out and it appears to be broken! :-(
So sorry to disappoint, but I'm certainly not in the habit of swapping or selling faulty stuff!
I do have LOTS of pickups though, some of which I'm thinking of moving on.
Is it a Realist specifically that you're after?
I have a boxed Realist Sound Clip and a boxed complete Schertler DYN-B system including preamp that I've moved away from now, amongst many others!
