<div>Hi Andrew,</div>
<div> </div>
<div>Check the postion of the letoff button rail. I've had several newer pianos at the lower end of the price spectrum that had the letoff rail too far forward(toward the jacks). The result is that the jacks get hung up between the butt and the rail with no place to go. It usually happened on hard blows, but it was intermittent, and extremely annoying!</div>
<div> </div>
<div>You'll have to regulate letoff if you do end up moving the rail back. </div>

<div class=AOLPlainTextBody id=AOLMsgPart_0_4b74614b-af44-4bed-a5cf-f424f27663b6>I had a chinese piano come in, a little upright with a few problems: <br>
<br>
bass strings buzzing, removed loose keypins from bridge: still buzzing <br>
rerouted bass string through its own bridge pins: fixed <br>
<br>
occasional key sticking hard to reproduce: figured out how to reproduce predictably <br>
try rapid cycling of key without fully lifting up, allows check to loosen and hammer to fall back without jack going under then jack catches on buckskin just back of felt cushion and the only effective release is the lost motion inducer (soft) pedal <br>
Solutions? <br>
<br>
