Yes, the mellos along with the other sections were bring natural smoke. JR & my crab brother and our Line Brother with Big Thunder, Trell was section leader and he had some horses to work with. I didn't recall 20 of them (JR probably can remember more clearly). I was thinking we had either 12 or 16 with that setup, as we did with Baritone. Doc didn't believe in having no more of those than he needed to be impressive. He rather have them on trumpet or trombone, respectively.
There was the optimum number for the Isaac Greggs system, 192 on the field. The 230 sounds more like what was in uniform in the stands. What impressed you was the creme' de la creme'. What didn't please us (internally) was that we saw and could tell by the lack of sound coming back to us on the last note, that this 192 was producing a sound that was less impactful than than the 128. We had already expected it would be that way or that it would get sloppy later in the year, because more of the reserves were drummers. Thus, there wasn't much of any compettion to keep those on the field pushed to retain a spot. So, you witnessed the only 192 on the field under Doc and beyond him, because we immediately went to 160 the following week and it was back on like donkey cone. Though the 160 caused us to extend our drills a little longer to move the extra line (5th line), we brought pure smoke after that. If I recall correctly, this was also the year that we got the drum contract through that hella percussionist that use to be in the Juke and we went to 8 Cymbals (instead of 4) on the field. They went to the large cymbals at that time (heavier and a lot more sound).
Not only was sound a premimum with the Juke, but dynamics. There was plenty of feelings in the music. I use to tell the boys that a hella singer can make their sound as though they are playing an instrument; Hella musicians make their insturments sound like it is singing. So, when you carried the melody, it sounded like you were doing just that. If you were playing the guitar lick, it sounded like that and not like the trombone, sax, etc... If you had the background vocals, it sounded like the background singers. If you had the synthezier/keyboard part, you sounded like that and supported the song with cordal structure. Every section with the exaception of the 4 clarinets, could carry a seperate part in the song and still be heard and compliment or enhance the song. There was depth and deminsion in the arrangements and that was also in each section and it was all heard, on and off the field. Yes, we joked with the saxs about having to look so smooth when they were DRIVING on the field because they couldn't be heard and had to be seen. But, that was all it was, a joke. Because, you heard them. If anyone has us blowing "You Brought The Sunshine" by the Clark Sisters, I think it is the guitar lick (the short dotted 8th note followed by a 16th note) was all them and that was the groove of the song along with the keyboard chords played mostly by tromebones and tubas.
Peace...
