I have a guitar with a K&K installed and it just doesn't cut it. Sounds fine just doesn't have the presence to suit me. Can I install an Element and then solder the K&K to the ring channel? The Element installation guide says not to use a high impedance pickup like the iBeam, but I don't know if the K&K is high impedance. I do have have a stereo preamp to mix two signals. Thanks.
