Installing K&K Pure Classic transducers

Post by Paul Nicholas » Mon Mar 27, 2017 12:04 am

Good Evening!

I am considering installing K&K Pure Classic transducers so I can plug in for playing at different venues. While I want the additional volume and benefits from plugging in, I'd prefer it to be as passive as possible. Is there any reason I would need to install a pre-amp or any other equipment? or can I get away with just installing the small mics under the saddle?

I have near zero experience with acoustic-electrics, so any suggestions or advice would be fantastic. I've always thought that pick-ups, electrics, etc. compromised the purity of the instrument, but now in some instances, I see the need, so I'm torn... Any thoughts?

The K&K passive systems are one of the less obtrusive in terms of external appearance, but you do still need to drill a hole in the end of your guitar for the output jack - not for the faint-hearted, especially if the guitar is valuable. I've used them a few times on my guitars, and the results are pretty good, although of course you get no "on-board" control of volume, tone etc. The lack of pre-amp wasn't a problem in terms of driving my AER acoustic amplifier.

With the K&K transducers, you have the option of installing them permanently with gel CA glue, or just with double sided tape. You won't get as much output if you tape them, but it does give you the option of removing them at some point in the future (although you'll still have the hole in the end of your guitar).


P.S. if you use the gel superglue, be sure to use gloves when installing them - you really don't want to end up with your hand glue to the inside of your guitar.

I've installed the K&K pure western on several steel string guitars. My clients were happy with the sound. I liked the fact that they are passive, so there are no batteries inside the box. And so, the big issue was not having volume, feedback or tone controls on the guitar. Though inconvenient, that can be handled down line. You will want feedback control. Your amp may have that. I know that one uses a clip on belt controller by LR Baggs.

I liked the sound over the quacky, brittle quality of many undersaddle peizo transducers that I've heard.

With the steel string the plug wasn't an issue.

Make sure you snug up the wires inside so they don't rattle around.
