Hands-On Review:Gibson CJ-165 EC Modern Classic Acoustic-Electric Guitar

A beautiful small-bodied guitar with powerful Fishman electronics

When I first took the Gibson CJ-165 EC Acoustic-Electric guitar out of its hardshell case I was struck once  again by how much I’ve always preferred the deep, dark woods that Gibson  uses on its guitars topped off with the with the gorgeous sunburst on  the premium Sitka spruce top. Too bad I can’t enjoy it as much when I’m  playing it, but like a custom-made suit, I sure do look good wearing it.  Then I saw there was no control panel on the outside of the upper bout.  I thought Gibson had sent me the wrong guitar to review. A co-worker  with a better view pointed out to me that the Fishman electronics were  mounted inside the soundhole. It made perfect sense to me: Gibson is  using a patented neodymium magnetic mounting system—no holes are  drilled, no special adhesives are used. You get the additional  electronics without spoiling the natural beauty of the solid wood sides  of the guitar. My review guitar has rosewood back and sides; another  model comes with maple back and sides.


The CJ-165 EC Rosewood Modern Classic and Maple Modern Classic are small-bodied guitars that have the same shape as Gibson’s classic  flattop Super Jumbo J-200 introduced in the 1930s. Why have smaller body  guitars become so popular? Of course, a smaller guitar is easier to  transport and carry around. One thing I like about smaller body guitars  is how my upper right arm rests more comfortably over the lower bout  without cutting off circulation the way my dreadnought does, which leads  to arm fatigue and discomfort. With the smaller guitar, my right hand  can more easily and naturally reach over the strings so I get better  coverage and better articulation. In a strictly acoustic playing  situation, a dreadnought will be louder and have more bass response.  That’s what they were designed for in the days before amplification—to  fill a room acoustically. But today’s smaller acoustic-electric guitars  can more than make up the natural differences.


Loud and clear


Basically, I want to accomplish two things with an acoustic-electric.  First, make the guitar loud enough to be heard in any listening  environment, and second, reproduce as accurately as possible the tonal  qualities of the acoustic guitar. But my immediate concern was how was I  going to learn how to access and adjust the Fishman system control  mounted inside the soundhole? As it turns out, the controls are laid out  in such a way that you can learn to navigate by feel in no time at all.


The controls closest to me, from left to right, are the Volume  slider, the Phase button that improves bass response at low volume and  suppresses feedback at high volume, and the Blend slider control to  adjust the balance between the piezo pickup and the selected mic model.  Because the shaft of the phase button sticks up higher, I use it as a  base to navigate to other controls. Behind those controls are the Sound  Image controller—a switch that slides among the four settings to select  microphone models. To the left is the Anti-Feedback on-off switch and  the Measure button that use a notch filter to seek out and eliminate  feedback-causing frequencies. To the right is the battery indicator and  the Low Frequency Tone Shaping selector that has two settings: bass  boost for solo guitarists and flat voicing that cuts through the mix  when playing with other instruments. To the extreme right is the USB  connector that can be used to download other mic models from Fishman.


A good blend


The CJ-165 EC has a built-in piezo transducer pickup that you can blend with  microphone modeling from the Fishman Ellipse Aura system. Because  rosewood and maple respond to string vibrations differently, each model  has a slightly different set of microphone models. The rosewood guitar  I’m evaluating came pre-loaded with four mic models that were created by  recording the CJ-165 EC:  a dynamic cardioid mic; the Shure Beta 58; two small diaphragm  condenser mics—the DPA 4011 and the Neumann KM84; and a large diaphragm  condenser, the Neumann U87. The maple guitar also has the Shure and the  DPA, as well as a small diaphragm Schoeps CMC64G, and a large diaphragm  condenser Soundelux E47.


When comparing how the mic models reproduce the sound of the CJ-165, I  should point out that no guitar has one perfect sound. That sound  depends a lot on the person playing the guitar: what type of strings  being used, how the guitar is held (is the arm draped over the guitar,  dampening the sound somewhat), what kind of fingerpicks, or bare  fingers, and what style of music is being played.


Mics for all seasons


To compare the mic models I ran the 1/4" output of the CJ-165 EC Rosewood Modern Classic into a small club PA with flat EQ settings. All of these mics have a  great reputation for being excellent for live sound or recording and  each mic model reproduces guitar frequencies differently based on its  characteristic frequency response curve and how the mic was placed when  recording the CJ-165 EC to create the mic model.


There are a couple of differences to note in the types of microphones  that affect their performance. The small diaphragm mics are especially  good at reproducing high frequencies and large diaphragm condenser mics  are very sensitive and used in studios to record vocals and a wide  variety of instruments. For each model I experimented with the Blend  settings with the piezo mic. When playing with other instruments I  wanted the more lively, responsive sound of the piezo mounted under the  saddle, so I moved the slider past 50% piezo (except when using the  Shure Beta 58 which has a fairly lively response, so I didn’t use as  much piezo in the blend). For solo guitar performances I wanted a little  warmer, woody tone, with just a bit of ambience, so I favored the mic  model for the DPA 4011 in the blend. For a little extra ambience, extra  clarity and even more pronounced woody tone I favored the studio  workhorse Neumann U87—a  mic that normally wouldn’t be found onstage in a live setting. The  Neumann KM84 provided lots of detail and clarity without getting too  woofy in the bass or too bright in the treble range.
