sorry havnt got back a little quicker but its chistmas and things are kinda hectic.
my advice analog would be to rob some younger sibling or go down the local charity shops and pick up something cheap a soldering iron is about 5 whatevers (depending on where your from) if it all goes terriblly wrong you can always resell the stuff on ebay .nothing to loose.
i hit the charity shops today and picked up a yammaha sh10 keytar with midi and 1/4 out.sweet :P
think i might be too scared to bend it and possiblly kill it ,i will check out the net for schemes tho.
link to some untreated sh10 bent sounds.
