Apologies - touch of brain fade. I'd say shimming is the way to go. The Ferro has never struck me as a particularly precision device, more a design centred on dependability, which given its origin as Admiralty-specified equipment, would make sense. That, and the fact that it was conceived when the sub-studio state of the art otherwise was the Brush Soundmirror...
