Percieved Difference in the Low end on the E string

[Jeff Gellis]

I am quite new to DB. I have been an electric player my entire musical life. I am playing a hybrid 3/4 DB.

Question is this; I hear little low end coming from my E string as compared to the other strings when playing my bass. When I amplify the bass the strings seem balanced in the low end they produce. I noticed when someone else plays my bass, the E string sounds like it has low end. I assume this has something to do with the length of the sound wave and/or the characteristic of my practice room. Does anyone else experience this or is this unusual? Ideally, I would like to hear uniform sound characteristics coming from all the strings when I play acoustically. Is this too much to ask?

Thoughts, suggestions, observations?
