So, any brand will be okay, but we thought there may be some exceptions. We checked with Rachel, and she gave us some clarity. She said that yes, she can repair other brands, but it's most sensible to send only handmade flutes (of any brand) to Powell for repair. For instance, if you happen to have a beginner flute, you should probably check with your local repair shop for service. The repair technicians should be able to service a beginner flute and charge service fees that (also) would typically be less than for work on a handmade flute.
Modifications on other brands are something that Powell would not be able to do. If you have a flute of a different brand and need new keywork or would like some type of mechanism modification, you would have to send the instrument to the original manufacturer. As we've seen in a previous post (follow this link to read it), it's not possible for other shops to order Powell parts (since each part is handmade), so the reverse is true for Powell when it comes to other brands (the original manufacturer would have to make the part and do the repair).
Finally, Powell would not be able to re-cut headjoints from other brands. If you have a Powell headjoint, recutting it is typically not a problem (although you would need to have the headjoint evaluated first just to make sure).
As always, if you have any questions, feel free to contact our repair office. Rachel, our technician, can be reached by phone at (978) 344-5164 or by e-mail: email@example.com.
