3 String Bass 5 String Guitar
OK bass players can have as many strings as they want but twangers DO NOT need a low E string. Those are my notes! OK if the twanger is playing solo act he can have as many strings as he wants but if he is playing with bass player having a low E string should be illegal and punishable by listening to Michael Bolton.
I know what the twang baggers will say, This is a redistribution of notes. It's sonic socialism! OK let the cry babies have 6 strings A D G B E A and with a shorter and lighter guitar you twangers can hot dog and showboat more and musically masturbate even faster.
Maybe we can reach a compromise, Get rid of the E and I will get rid of the G and I'll stop banging your girlfriend. 

Sounds like you need to start playing with Uke players. Or stop playing your E's on the A string.

I play in a band that uses D and Drop C tunings and while that does go into bass freq's my D (or C respectively) still booms way more than their tiny D strings.
Maybe you just need to turn your bass up?
I mean, the guitar E is an octave away from your E. The frequency is different...also, I use to get in troule for playing too fancily up high on the neck, interfereing with my twanger's frequency. The complaint goes both ways. Just play as a band, have good communication and do your part.
More and bigger cabs is the answer. New possible band project involves an 8 string, so we are crossing a lot of eachothers ground. I am confidant I can open a lot of ground right at the bottom.
Volume isn't the answer for getting rid of mud, wire cutters are.
Giving a twanger 82.40 hz is like giving whiskey to the Indians.
Nice way to pop in Chris! haven't seen you in a while. Sounds to me like you got a bit of a battle on your hands. I think Keith Richards has it right. Good luck in your battle and don't be a stranger.

that's terribly inappropriate, and if I wasn't laughing out loud I'd give you a hard time.....
I can drown out any guitar players low E with my low E so maybe you need some help with your tone and rig 
yeah lets make fun of native americans. Dont act like you other folk dont get crazy as hell with a little drink in you.
as for your Guitar players not having an E, good luck finding a twanger to sign off on that one.
rock.
DDD
Well that would be 8 strings in a 3 piece.
Presidents of the USA did 4 string guitar and 2 string bass.
Just about the winner
We use 2 bass's, a 5 and a 4 string.
Just shows its not the size of the strings its how you use them

Dang boy.
We need guitarists to form a band.
One of the best in the world, Keith Richards, removed the low E string on his axes a long time ago
stating that it just got in the way and he didn't like to play bar chords.
