From 1969 to 1976 I played my alto and soprano thru a similar device made by Hammond called the Condor. My mouthpieces were drilled and threaded to accept the screw-in pickup holder. The Condor had colored tabs that looked like organ stops. Each gave a different sound - oboe, bassoon, bass clarinet, banjo, organ, tuba, french horn, trumpet, flute, etc. The Condor would play as many as 3 octaves at one time, each with a different timbre. There were controls for volume and tremolo. I ran the output through a vox crybaby wa-wa pedal and on to an Ampeg V-4 and 2 speaker cabs each with a pair of Electro-voice 12" SRO speakers. I played the orchestra/synth parts in Yes and Moody Blues tunes, horn parts in Chicago tunes, and the harmony guitar part in Allman Brothers tunes. The wa-wa was cool. I played Traffic's "Low Spark Of High Heeled Boys" and Frank Zappa's stuff off the Chunga's Revenge album. I stopped using it because it was a pain to carry all that stuff and because the natural sound of the sax was not as good through the system.
