Warranty Information

Every Zendrum and Zendrumdrive is designed, built, and personally tech supported by Zendrum inventor and co-founder David Haney.

Should you EVER need service or upgrades, Zendrum Corporation is a user-friendly, personal service-minded company.  We stand behind every instrument we build, and our good reputation depends on your satisfaction.  We do not anticipate that you will ever experience mechanical failure, but if problems do occur, we will be happy to troubleshoot, tech support, and if needed, repair your instrument.  You will be responsible for shipping charges, as well as customs, duties, taxes, etc. where applicable.  Zendrum will be responsible for parts and labor only. 



David Haney, Inventor and Co-Founder




Zendrum Instrument Warranty

The Zendrum is warranted “for life” (meaning David Haney’s lifetime, not yours) from defects in workmanship, provided it has not been modified from its original factory state or abused.  The warranty is in effect as long as YOU are the original owner of this instrument.  It is the sole judgment of Zendrum Corporation to decide what constitutes abnormal wear and tear.  Tampering with any circuit board, internal components, or wiring will void your warranty and could permanently damage your instrument.

Our percussive instruments are designed by drummers to be played vigorously with the hands.  They are not intended to be played with sticks or mallets, and doing so will ultimately void your warranty as well as potentially damaging the triggers or finish of the instrument.

Our MALLET INSTRUMENTS, however, are intended to be played with mallets but NEVER drumsticks. We recommend a medium rubber or yarn mallet.


Zendrumdrive Warranty

Every Zendrumdrive is warranted for one year from date of purchase provided that it has not been abused, modified, or altered.  What constitutes normal wear and tear is the sole discretion of Zendrum Corporation.  We will warranty parts and labor and our default programming only.  We cannot warranty additional third-party software, hardware installed by the end user, any files uploaded from external sources, or any damage caused to outside equipment by altering the original factory state of your Zendrumdrive.  We cannot warranty any changes you make to our settings or configurations.  In the event of shipping back for service issues, you will be responsible for all shipping fees, proper packaging, and providing adequate insurance coverage.  You must understand and accept your personal responsibility before connecting your Zendrumdrive to the internet, downloading and installing software or hardware. While it is possible to do many things other than the default programming and setup performed by Zendrum Corporation, our legal liability for your actions must end where your personal actions, including but not limited to alterations and modifications, begin. 


Caring for Your Instrument

Our instruments are hand-carved from solid hardwood. Regardless of finish type these instruments should be protected from the elements, as wood will expand and contract with exposure to dampness, humidity, or extreme heat or cold. This can potentially warp your instrument or damage your High-Gloss finish. Please store and transport your instrument with this in mind. These, and all other Zendrum products, should not be left uncovered for lengthy periods in direct sunlight, as damage may potentially occur. We recommend using compressed air to dust your instrument and keep particles from scratching the surface. Wipe surfaces with a clean, soft cloth to remove fingerprints. Double check the closure of your instrument case or gig bag BEFORE picking it up. Inspect all power supplies and cable connections regularly. Do not put wires and power cables where they will be stretched or stressed to the limit. Do not bind the cables where they will become crimped because this will damage the internal copper strands.


Instruments with Live Finishes

Any instrument with a live finish (including, but not limited to, Zebrawood instruments or Walnut surfaces on our Mallet Pro Series) requires regular maintenance to keep them looking their best.  These instruments should not be subjected to extreme humidity or temperature conditions, and as such, should always be stored in reasonable areas not subject to large swings in humidity or temperature.  Any live, non-gloss, finish (such as the Walnut on our Mallet Pro series) can be maintained with regular application of an appropriate wood care oil such as Old English or Danish Oil applied to a clean, soft cloth and NEVER poured onto any surface.   


Damaged Finishes

In the unfortunate event that an accident does occur, please contact us immediately, as certain damaged NON-GLOSS finishes may potentially be repaired by you without the need for returns.  Any instrument with a cracked high gloss finish can be returned to Zendrum Corporation and refinished for $400.00.  In this event, all shipping charges incurred will be the sole responsibility of the customer.



In the event that you wish to return a Zendrum Instrument, Zendrumdrive, or any other product sold to you by Zendrum Corporation, you must notify Zendrum Corporation within 2 weeks of delivery of your order, including an explanation of why you seek a refund and full disclosure of any other contributing factors.  Upon the sole discretion and approval of David Haney, you must then carefully pack and ship your product (following the packing and shipping guidelines that will be provided upon approval) back to Zendrum Corporation for inspection.  You will be solely responsible for all shipping charges associated with any return or denied return inspection.  To meet return inspection requirements, your product must be in the exact condition that it was in as it was inspected while being packed for shipment from Zendrum Corporation.  If your product passes inspection by David Haney, you will then be issued a refund minus any shipping charges paid, and minus a 15(fifteen) percent restocking fee.  The net refund minus any fees will be paid to you within 30 days of return inspection and final approval of the refund.  If your product fails to pass return inspection, your instrument will be shipped back to you, and you will be held responsible for any and all shipping charges. Before pursuing a return or refund, however, please allow our Tech Support to resolve whatever issues you may be experiencing.
