Even string volume

[2Loud4You]

Ok, I did a search and while I'm sure there's something on here about it I didn't come across so I'll ask anyway.

So I've got 2 6 string basses (Roscoe LG3006 & Ibanez BTB1006), both tuned a 1/2 step down with the B & E tuned to A flat and D flat respectively. Both are 35" scale with 18v active pre amps & Bartolini pups. The Roscoe has good even volume between the strings with a solid lowend even down to A flat. The Ibanez has a good strong E (D flat) but the volume drops off dramatically on the B (A flat). I've thought about raising the pups on the bass side but feel like that will accentuate the E as well and not necessarily fix the volume difference. Admittedly I noticed it a little when I 1st got it but it seems more apparent through my new cab. It also has new strings, D'Addario .032 - .135 so I don't think it's an issue with dead strings.

Anyone come across this problem and how did you solve it? The bass sounds great but I need the B's volume to be more even with the other strings. Thanks for any help.

The bass on the right is the Ibanez.

I am having a similar problem with my Schector Studio 6 - I play 1 whole step down (A D G C G F Ab) in a Metal band; the B, E & A all sound sweet as, the higher 3 strings seem to drop off a bit.

I think perhaps fiddling with you're (my) EQ may fix the issue. I will try this tonight and let you know how it goes.

Well the eq setting I have now souds great with the Roscoe. I don't really think it's an amp issue otherwise I'd have a similar problem with the Roscoe. My Roscoe booms through the speakers but the B just drops off on the Ibanez.

Higher string tension (on the treble side) means less string movement and less for the pickups to sense. Odds are you have a dramatic difference in tension form high to low. See if you can come by D'Addario's tension chart and see if your strings are close in tension based on your tuning.

IMO you should have no more than a pound or two difference from one string to the next.

raising the pickups isint a good idea..

its not likely but one thing that came to mind is fretboard radius. sometimes that makes the string volume uneven..because differnt strings are differnt distances from your pickups.

does one have more of a radius than the other? really, a flat fretboard (though uncommon) is ideal..
