K&K Double Big Twin question

Postby Bob Francis » Sun May 27, 2018 10:32 am

I bought a K&K Double Big Twin pickup for an EUB that I built several years ago.
The problem I have is that when I hold one of the piezo elements in position it sounds great. When I taped the first one into position it barely registers a weak and tinny sound. down. The instructions suggest taping with a piece of double sided tape (provided) before gluing with super glue.

Any suggestions are appreciated!

I recently fitted a K & K kit to one of my acoustics. I found the double sided tape pads supplied with the kit to be completely useless, the instructions do say that you'll have better results using a gel super glue, I drilled some tiny holes through the bridge and top and put some wire through to locate exactly where I wanted the pickup "pads", and after a dry run I applied the glue and stuck them in place completely omitting the tape, I was actually doing it on a round hole archtop with quite a small sound hole and found it a real fiddle so it might be easier in a flat top with a regular size hole.

With the tape holding the pickup pads the sound was so weak it was useless and the pads fell off in under an hour, but with them glued in place the sound is fine, weaker than other systems but the most realistic acoustic pickup I've heard.

Great confirmation on that blasted tape.

We used the big twins in a pair of bass banjos that my apprentice built. He ended up making an adjustable "foot" that pressed the pickups up against the skins. The volume improved by a factor of 3 or 4 and the low end became totally solid and even up and down the scales. All the guitar installs I've done were with CA glue as per the supplied instructions and I've never had a complaint with this system.

Thanks David,
I like the thought of the adjustable foot . . . I need to dig up some hardware.
Will post pics when done.
