In this episode I demonstrate how to fill a Floyd Rose tremolo cavity before installation of an Evertune bridge. This method can be used to prepare a guitar for any replacement hardtail bridge. I make these videos as I work using the iphone 6 plus. You are watching real processes.. This video is information only – a degree of woodworking experience and tool operating ability is required to replicate the processes I demonstrate. I can accept no responsibility if you attempt anything in this series that is outside your practical reach and damage your guitar.
