16:23 Harmonics is factory authorized to handle Seydel diatonic and chromatic repairs, warranty service, and custom set-ups. Before shipping your Seydel for service, complete the customer contact form and read the information below.


Seydel chromatic repair prices can vary but generally run about $35.00 + return shipping of $6. Where possible, I will replace broken brass chromatic reeds with a polished stainless steel reed. 


As a service to my customers, I will generally inspect the entire chromatic and perform any other needed routine maintenance.  


Chromatic harmonicas can be shipped in the Seydel hinged chromatic box as pictured. Be sure to enclose a note with your name and address and a description of the problem.

Please enclose a note with the harmonica. I receive a considerable number of packages each week and those without idenifying information are my lowest priority. 


I have found USPS Priority Mail shipping to be the most efficient.  The USPS provides the box, the parcel is tracked to delivery, and USPS packages are delivered to my doorstep or lockbox.  The cost is about $8.00 and a small flat rate box will hold up to 8 diatonic harmonicas or 1 chromatic.  


As a service to my customers, I offer prepaid shipping labels which I can email. Alternatively, I am can send a box with packing materials and a prepaid shipping label attached.  


Because of the extremely high volume of harmonicas I receive, it is difficult for me to provide personal confirmation on receipt. Please check tracking before contacting me to check on your shipment.




I prefer to complete the repair before invoicing.  I will send an email with a link allowing payment by Paypal or credit card.  


I am often asked if I work on brands other than Seydel.  I am in partnership with Seydel and the company is committed to

players even after their purchase.  Seydel insures that I am supplied with reeds, springs, and other parts so that Seydel repairs

can be made efficiently with minimal cost. I would be unable to provide the same level of service on non-Seydel brands. However,

I will gladly refer you to some great technicians who can handle non-Seydel repairs.  Note that as a service to my customers I will provide a prepaid shipping label via email.  Alternatively, I can also send customers packing materials and a box with a prepaid shipping label.  

I can be reached at (210) 445-6600.

Seydel diatonic repairs generally start at $17 + return shipping of $6. Additional reeds on the same harmonica will run an additional $5.  The repair fee will include a quick check for reed performance and tuning but I can't promise other reeds will not fail.  


I will replace all broken reeds with a polished stainless steel reed. In my experience, the replaced reeds will not fail again.  


Diatonic harmonicas can be wrapped in bubble wrap or packing materials.


Enclose a note inside the package with your name and address.    


I extend preferred repair rates and turnaround time on Seydel diatonic harmonicas which have been purchased directly from me


Conversely, I charge higher rates on harmonicas purchased from Amazon, Guitar Center, and the other online discount retailers.  Customers should plan on a longer turnaround time.
