[CAUT] Agraffes and dampers

[Shawn Brock]

Man,
you are not the first to have a problem with Petrofs being string breakers. 
Some of the ones that I have had dealings with would brake bass strings 
while not being played!  They would come in and just be out of the crate 
and....  Pop, ping...  Its a shame they could have a good product but... 
Sorry I'm no help but I just wanted to let you know You are not alone.
