I wish to add a slap plate to my Warwick Streamer Jazzman fretless, so I can slap it without chewing up the fingerboard. I searched for old threads and its been mentioned but there wasnt much info... Does anyone a) know of anywhere in the UK I can contact to get this done or b) know how I could go about making and fitting one myself? I'm terrible at doing this kind of stuff however... Many thanks in advance for any advice you can give me!
