Before you do the soldering, make sure you like the two units together. I used two for a while but went back to using one because of a noticeable phasing effect with two.

Double Bass Ehrlund, Schertler or DPA

Unlike VinTone I've had excellent sound and volume from the Ehrund EAP into a Grace Designs Felix. I owned a DPA 4099B and liked it, but at the time they didn't have the Gooseneck extension so I couldn't get the mic placed
exactly where it needed to be without a lot of fuss and it never really stayed in place. The DPA is a great FOH mic but back into an amplifier not so great even with the shotgun design.
I use the Remic 5400DB Red for Recording and Remic DB 5400 Green for live gigs along with the Ehrlund EAP. Just my take however. The older original two element Stat B's had their own preamp that worked very well with that pickup.

Hi Eric
yes, sure, for now I have them connected thru an Y cable. But I like the sound so far. I saw other speculations about phasing, but I think that what some people hear, is not phasing, but something that sounds similar.
It might be that the characters of the mikes do not match. Either because of differences between the mikes, or because of the positioning and cork shape that differ.
If you look at the ‘physical model’ of the bass, then the string generates the energy that is passed through the bridge to the body. the bridge has two feet, and the distance between these would cause timing and thus phase differences . But the sound of the string doesn’t travel thru air, but through the wood of the bridge. And the speed of sound through wood is around 4000m/s. As opposed to air, which is around 320m/s. Since the speed is more than 10 times as high, the distance between the two feet is ignorable phasewise.
Another thing is that the bridge doesn’t move symetric. (Unlike an acoustic guitar) Because of the pole on the G side, the E side of the bridge moves different than the other side. If the sound of each mike is not ‘balanced’ but has a more erratic freq curve (caused by difference in position and cork shape), then those two mixed might cause an effect similar to phasing. The result of phasing is comb filtering, which is kindof an ‘eq’ with a lot of peaks and bumps. (Sorry, English is not my first language;-)
I would compare both mike sounds separately, and check if they have a different character. Swapping sides might also give interesting results... Or keep one mike of course, if you’re happy ;-)
Thanks, Daniel

That's quite an explanation, and your English is just fine.
A suggestion was made, possibly by someone at Schertler, to use an opposing orientation of one of the pickups. I don't remember hearing a difference, but might as well try it.

I've had most all these pickups, and from reading all the conflicting information you can see readily that the bass is the single factor that makes the biggest difference. An EAP on my small bass sounds utterly fantastic but on my 200 year old Tyrolean it sounded terrible. Unfortunately you just have to throw the dice and give it your best guess and then be willing to adjust as you can. The EAP for arco though is really pretty cool.
