Microphonic out of the box
I bought a pair of the “preferred series”for my pro junior. They sound good, and have a lot of gain, but they were extremely microphonic. Aren’t they supposed to be tested and screened for this? They are playable but ring on like ud notes
Won’t buy these again—I can get tubes exactly like any time. Disappointed in thestubestore
Note from thetubestore.com: Sorry to hear this. All Preferred Series tubes are tested and screened. Occasionally a bad can get by. Be sure to contact us directly so we can look into this further. There is a 6 month warranty on all Preferred Series tubes so contact us soon.
