I have experience working on this model. They are quite impressive
after a professional set-up of reed profiles and offsets. Yes
there's a mild waiting period, because reeds usually need some time
for the internal stress from adjustments to go away before tuning
will stabilize, but it's worth it to have it done right.
I can also repair them. Brendan Power arranged for me to recieve the
factory special Suzuki tools to professionally deal with the welded
reeds and it works really slick. So far Suzuki won't sell me the
Fabulous reeds, but I can make Hohner reeds fit. I do have reeds for
the other Suzuki diatonics, for what it's worth.
Suzuki does have a customer service/warranty contact, and I'm sure
he would try to do something for you. But if you might be interested
in having me bring out the potential of this harp, I have room in my schedule.
