Kings are nice congas, no overtones, no ringing. They have a nice dry sound, just like Echo Tones. I should have kept mine (photo enclosed). I hear Armando Peraza, the original endorser, has a garage full of them in SF. I should give him a call, I know him since the days he was in Mongo's band. Armando, Candito and Francisco, the last of the Mohicans left (MoCubans).
May God bless them!
