The sound is thin.
Lacking fullness in the
lows and low mids.
The sound is starting to warm up.
The lows and low mids are starting
to improve and fill out.
The sound is now coming into focus with a nice balance of lows, mids and highs.

This is the best sounding sample
with the pickups in phase and a great
place to start applying EQ settings.
The sound is similar to having the Phazer at 75 degrees but a little thicker in the low mids and lows.
Coaxial and Sensor out of Phase - No Phazer Applied
Coaxial and Sensor out of  Phase - Phazer at 45 degrees
Coaxial and Sensor out of Phase - Phazer at 75 degrees
Coaxial and Sensor out of Phase - Phazer at 90 degrees
The sound is thick
but a little muddy.
The sound has opened up and is
a good starting point to add EQ.
This is my typical starting point when
adjusting my sound at a gig.
The sound is still good but a little thinner than
when the Phazer was at 45 degrees. I sometimes
perform with these settings as well.
Now the sound thin again because the pickups are back in phase and out of alignment.

The Carlos Juan pickup system is comprised of two pickups. These being an under the saddle transducer and a sound board sensor. The under saddle transducer is a tubular coaxial wire that enter and exits the saddle slot at 45 degree angles. The sound board sensor is a small square carbon fiber housed sensor that connects to the sound board "top" of the guitar internally or even externally if desired. Each pickup captures important frequencies of the guitar. The under saddle pickup captures a full range signal but most importantly, upper mid range and high frequencies. The sensor captures more lows and low mids frequencies and any tapping or golpes applied on the top of the guitar.

When the two two pickups are combined they create a natural and dynamic sound of the guitar. However, whenever two audio signals of the same source are combined, phase issues usually occur causing comb filtering. This typically results in thin or muddy sounding signals. To get the best out of the Carlos Juan Flamenco Doble I highly recommend using the Phazer from Radial Engineering which does an amazing job of balancing the sound and bringing it into focus.  Typically the coaxial signal arrives about 2ms earlier than the sensor signal. So I use a Y-cable out of my guitar and run the coaxial signal through the Radial Phazer and then into my preamp/mixer. The Sensor signal goes direct into the preamp/mixer.

I almost always run my guitar with the pickups out of phase with each other and the Radial Phazer set between 45 and 75 degrees. The phazer setting depends on the sound I'm getting in the vernue.  Below are 8 audio samples. 4 in phase and 4 out of phase with 4 common settings of the Radial Phazer.
