Hi - this is sort of a custom pickup as I took a Dean Markley and sanded it down to be as slim as possible. It is about 11mm-12mm tall and can be attached to the top of a gypsy guitar with putty (which sorry I am not including). The pickup is quiet and though not a stimer, it works well as a basic way to amplify your guitar or certainly as an emergency pickup if your main pickup failed on a gig. Please email me if interested at deanoguitar at gmail dot com. Thanks, Dean
