There are bass solos on two of the 16 tracks on the cd

One upright, one electric...
James, duly noted, and thanks...I agree with all of that.
And it's all original material, but you knew that
I've got a log of what basses were used on what tracks if you've followed my "bass a day picture thread."
Basses aside, it was TFB420/Schroeder 1210, with a radial throwing signal to the board, and thru an avalon pre, so I have three signals to mix.
