Hi Sherri
I am no expert, but I understand that the placement of the bray pin can give a range of sounds, from subtle purring to something more forthright. So “exacting” is actually a good thing because it embodies lots of possibilities. I also like a harp with brays set on the bass and the top sounding clear.
I’ll post progress as it happens. We are also working on an ‘affordable’ harp using a metal neck and pillar with levers integrated into the design.
