I wish I had not replied about the respective qualities of the electric bass and the orchestral bass.
As for a direct practical demonstration, this actually happened to me. I was playing in a school production of a musical [West Side Story], and the ballet scenes were re-scored and arranged for rock-band. So I was surprised to find that I had a part to play even though there was a powerful electric bass guitar also playing.
I assumed that this was a mistake as there was no way [in my mind] that I could keep pace with four big speakers in a huge cabinet!
I layed off and the conductor [at the rehearsal] asked me to play. This was awkward to say the least as it was hard to hear myself playing. All pizz. [plucked] in these parts.
Of course there were several people in the body of the hall during the rehearsals, so I asked one [whom I knew as a friend] whether I was adding anything at all to the ensemble. Apparently further back, I was making a clear and rhythmic contribution that was much more focussed than the electric bass. I found that a great surprise, especially as [under the player's ear] I seemed to be only barely audible. There was no great pleasure in that for me as you have to be able to hear yourself to play well and in tune. Fortunately the notes fell in the lowest positions on the finger board, and not in no-mans land further up! So I stayed in tune in spite of the seemingly much louder amplified bass near me.
Just a little story from my playing days, but if you play the bass you get asked to do some quite musically incongruous things!
Best wishes from George

The dark brown bass [without me in the picture] is the London bass circa 1770/1780, which once belonged to Gustav Holst, and was insecurely attributed to Father Fendt. The nut brown five string was finished in early 1996 by Ian Highfield of Rednal. Both are strung with gut, except that the five stringer had a steel low B string. You can get a B string in gut, but thick as a clothes line! Also the E string is silver round wire covered gut rather than plain as in the three higher strings. Sorry about the quality of the amateurish captures, but they are examples of my hopeless photographic skills!
