These are objectively awful instruments. They were so bad (and hard to get), that it was a common practice to make your own. For these purposes, the public phone booths were frequently vandalized as the pnones contained mics, that could be turned into pickups. Yet, much of the punk and rock stuff of the former USSR has been and, in some cases, are still made with them. E.g. Villu Tamme, legendary Estonian punk still plays a Musima Lead Star and it’s a key part of his sound.

Musima Lead Star is a musical instrument, Ural "guitars" were not. I played and owned several ones during eighties. The moment I could finally afford Musima Lead Star and finally get a sound I had in my head, was one of happiest moments of my life.
