For uk peeps I've just ordered some bushings from here -
www.synthrestore.co.uk/products.htm
I'll probably be back on next week asking how to put an Arp back together!!!

ah man, you are a top dude! I tried googling but had no luck, thanks for your help!

Is this tricky? I have the black and gold face one and two of the keys are sticking up higher than the rest. They still work fine just look kinda rubbish! I wondered if it was an easy fix?
Cheers for any help or tips
