Forum Members and Pearl Family,
This thread just came to my attention and I must apologize to anyone that feels their query has gone ignored. As excellently as the Forum is moderated by giants like Al and D (as well as personally monitored by our CEO,) there are times when things slip by. All apologies and no excuses, we were remiss and ask for your forgiveness and patience.
Please remember that if you ever have an immediate issue that needs attention, you have a DIRECT line to the company via our Contact Ticket Portal on the website:
The messages submitted there go directly to (and are answered by,) our Customer Service and Product Managers. Our goal is to personally answer each query within 24-48 hours (depending on Holidays, schedules, ect.)
That being said, the detuning issue several have discussed in this thread has come to our attention in rare instances before. The answer you received was actually correct; in most cases a more rigid shell like Acrylic doesn't often absorb the vibrations coming from impact, thus allowing rods to come loose as the vibration is transferred through the lugs. As Pearl's Crystal Beat's are seamless cast shells (and not rolled like RCI/Ludwig/OCDP, ect.) they are more solid for that no-overtone sound and feel, but have been known to have this affect on some tuning points.
I liked the thought of using Teflon Tape (hadn't considered that before but definitely a valid fix,) but to each point, we want to make sure you are getting the most from your instrument. One solid fix would be our Stainless Steel tension rods, which will have a more secure fit and are available on our Reference and Masterworks drums. Please reach out to us through the Contact portal mentioned above, we would love to be able to assist you further.
Thanks again for all your support and patience!
