Hi I have abut ten easymute tremolo arms I love them, they are like Marmite "You either love em or hate em"..........I've had the cheap one off ebay I and others will say it does the job, but so does a Mini and a Rolls Royce !! but I know which I'd sooner have.....Why not support a British Music Shop and the makers of Easymute, it's a quality bit of kit endorsed by Hank Marvin.....
