I’m having the same flat sound with my Strikes and Spares on the long bar. The first thing I did was rebuild everything in the chimes including the plungers. Still was flat. I switched bars with Mata Hari, then MH was flat. So u just ground down the length of the long bar? I never thought of that. I’ll check the length of the long bar. The rest of the chimes on SS sound good. That flat sound bugs me too as my EK and MH have the sweetest sounds to them. Thanks
