I am new to Casio Music Forums and currently own the Casio WK-3700 keyboard. For Christmas 2018, I just recently purchased the PX-560 from an online music retailer for my oldest daughter who graduated with a music education major and will soon be teaching students. I am excited about all the features and creative options that the PX-560 can offer her.
Unfortunately, after unboxing and testing out the new PX-560, I have found some subtle yet noticeable issues with the new board.
Here are the issues in order of importance to me and my daughter:
1) When playing the keys B4/C4 at the same time together quickly or rapidly back and forth between them, a noticeable tick can be heard coming from either the keybed or the lower part of the case on key release. I think it possibly has to do with the dampening felt that may be slightly out of place or something, clearances between the keybed and case, or possibly not enough dampening between the keybed and case. The keys still play smoothly and with the volume at a high enough level, I can't hear this tick. But, if you are playing softly or the volume is turned off, this 'extra' noise is apparent. I believe there is one other location where I hear something similar at B5/C5 but is not quite as pronounced. Otherwise, the remainder of the keys exhibits normal key action sound.
2) When playing at volume level around 60% and the low EQ set (default as K1 knob) higher than neutral (00), a buzzing sound can be heard from the left speaker when playing some of the lower keyboard keys (specifically G2) using certain tones including the primary Concert Grand Piano tone. This buzzing does not seem to be coming from the actual speaker audio but rather induced from the vibration/resonance of the speaker when interacting with the case or parts within the case. Others on this forum have mentioned this problem and one said the issue persisted on a 2nd keyboard even after returning it.
3) The volume knob is slightly out of round or not placed quite centered in the case hole so it rubs and is physically a little harder to turn between off and about 25% volume level.
4) The settings jog dial is also not centered quite right and, when turning it in a counter-clockwise motion, it seems a bit catchy upon rotating.
Overall, the PX-560 seems like an awesome instrument and is wonderful to play, but some of these issues are quality nuances and could worsen where they are no longer subtle anymore but have a real impact on useability in the years to come.
On this forum, I have specifically read of other PX-560 owners having similar issues to 1) & 2) above and am concerned that if I swap it out, the issues may be also present in the next keyboard (or possibly worse). Or, if these are issues stem from the design or manufacturing processes, should I be second guessing this unit as my keyboard choice?
When I purchase a digital piano, I am expecting years of use from it. With my WK-3700, I have never experienced any quality issues at all so this is new turf for me. And with paying over $1000 for the PX-560 that is only a week old, I am trying to decide what the best course of action to take to rectify these out of the box issues. Should I RMA the unit and ship back to the online retailer, or immediately exercise the warranty on the unit and hunt down a factory authorized Casio service center (which may not be easy since I reside in a rural area and it would most likely also involve shipping - Minneapolis/St. Paul is closest Metro area for me).
What is the best action I can take to assure my quality concerns are resolved?
Please advise and thank you in advance for your response.
