Hi guys,
I owe one (Ovation Celebrity) myself.
A friend of mine handcrafted a new sustainblock out of brass. Works great. Lot of work ... time.
But EACH of those Jinah sustainblocks are crap. They brake under pressure - promised.
Try to bend the whammybar up or down a few times and *clonnng!!*.
The great the guitar is, the unusable she is because of scriciolaring block.
