Double Bass Slap transducer position? HELP!

Hey folks!
New member and first time posting, I've come here for a bit of advice from someone who may have abit more knowledge then my self.
Pretty much I've been playing rockabilly double bass for sometime now using a make shift transducer I made myself in the wing of the bridge, recently bought myself a new bass and a new pick (a dual pick up with a wing transducer and a behind the neck transducer for slaps).
Me being like an excited school kid I jumped straight in and put the pickup on attatching the neck transducer directly behind where I slap... know the question is have I put the transducer in the correct position? My initial thinking was bigger and better volume but I'm not really getting a "slap" sound? It's more of a low bass thud everytime I slap? Any thoughts out be greatly appreciated!

Thank you in advance!
 
Mine sounds best dead center just above the scoop on the underside of the fingerboard but trying different areas will get you a different sound. Did you also tape the cable? I was getting a strange bass thud no matter where I put it until I taped the wire down for the whole length of fingerboard.
 
1) If you aren't using a dual channel pre-amp to blend your two piezo channels, you probably aren't picking up sound from the fingerboard piezo, the sound you're hearing is probably being produced by the bridge wing piezo. You can verify which piezo(s) are active by simply touching either piezo with your finger while the amp is hot, you'll hear your finger rubbing the piezo.

2) As Jason has indicated, the wire for the fingerboard piezo needs to be somehow anchored so that it won't rattle and produce noise on its own. I use a self-adhesive velcro sandwich attached under and for the length of the fingerboard overhang to contain both the fingerboard piezo and its wire. It works very nicely, and the piezo and the wire positions can be changed very easily without having to replace piezo adhesive.

I agree with both the placement of the klick Pickup. I’ve been putting as in the same place as jasonrp since 1999/2000.
You can use any tape to tape the wire under the fingerboard. I personally use Gorilla Tape. And of course a two channel pre is absolutely necessary.
