Microtech Gefell Repair Info 


DSPdoctor has been appointed by Microtech Gefell to act as the intermediary for all of their microphone repairs within the United States. We have been performing this service for MTG for close to ten years.


If you are in need of repair or service on any Microtech Gefell microphone and you reside within the US, you can send your mic to us and we will then send it along to Gefell in Germany for reapir or service. We perform these shipments monthly on average.

When the mic is received at Gefell, they test it thoroughly and then let us know what repairs are needed to bring your mic back up to original factory spec. The most common repairs consist of replacing a FET or replacing a capsule. 

After Gefell receives the mic and tests it, they will then let us know the specific issues they found and the cost to repair them. At that point, you can decide to perform all, some, or none of the repairs. If you decide against any repairs, you are still liable for all shipping costs to get the mic to Germany and then back again. After your repairs are complete we will contact you to let you know the mic is ready to return home. At that point payment for the repairs is arranged.

The average turn around time for service, from when you ship your mic to us to when you receive it back in full working condition, is usually 4-6 weeks.
