Double Bass Magnetic pup - LACE ALUMA P

... thought I’d see what the members think of my new magnetic p/up.
... checked my parts draw where I have a collection of discarded P-bass p/ups … but I decided to buy the new LASE ALUMA-P because they are light, cool looking, and they can accommodate 4, 5, and 6 string electrics (so I figure why not DB).
I mounted the ALUMA-Ps on a piece of PVC cut from a section of gutter moulding which followed the curvature of my strings. The best sound to my ear, is with the treble side furthest from the bridge, which of course is the opposite to the P-Bass configuration.
The p/up assembly is mounted using flexible tubing fitted into corks bunged into bridge (I always wondered why those 2 holes were there) and this pretty much gives unlimited positioning possibilities. The p/up also can be removed from the bass in seconds leaving no trace.
I haven’t earthed the strings yet, but initial testing at home shows no great problems with interference / buzz.
The sound is surprisingly good (IMO) and the variation in tone as the p/up is moved laterally along the string is also surprising. The flexible tubing (ratted from a laptop USB LED light) holds position really well, and allows for fine balancing of the strings to be achieved.
All in all … I’m happy with it … and am looking forward to trying it with my regular big band gig.
I also plan to mix it with my Fishman FC and DPA 4099.
If there is any interest I’ll try to post a few honest sound clips.

yes ... I'm wondering what others have done to ground the strings ... I'm thinking of brass washers behind the string ball ends soldered to the signal earth (better than a braided wire threaded through the tails I suppose).

... here's a better pic

mjmeche, good point ... I see that in the LACE blurb that the pup is current (as opposed to voltage) drive ... but not sure how that translates to producing (or negating) ground hums ... there is a bit of buzz as I turn the gain up ... it goes away when I touch the pickup though.
I haven't don't anything special with shielding as yet ... could use some of that stick on copper behind the assembly and over the twisted wires that I have coiled up there I guess ... thanks for your idea!
