Best accoustic sound amplification for gypsy Guitars:

We are presenting here what we consider to be the best pickup system for gypsy guitars. We are preparing a full picture and text presentation, with videos with lots of sound comparison. This marvel is made by Patrick Inghilleri in France and it is the answer to your sound amplification problems. There are many different solutions, depending on the sound hole type of your guitar. The best is made of two things: a special amplified bridge and a microphone, coupled together. The bridge gets the top movements and the microphone the air movement in the body.

Patrick also produces the creme de la creme pickup system for high-end gypsy guitars. The bridge has a dual sensor array to pickup strings vibrations, and he uses a revolutionnary concept called Widex (listen to this nice video, in french, of the Widex system, the only secure solution to avoid any larsen effect). Patrick pickup has three sensors: One which picks up the sound of the body from within the soundhole, one which picks up the sound from outside of the soundhole, and one omnidirectionnal pickup using the Widex anti larsen effect technology.

In a market where technology has been far from being satisfactory, Patrick Inghilleri through his creativity and scientific approach offers the only true solution for demanding players.

Primer: Gypsy guitar amplification solutions and the Inghilleri System.

Apart from some undesirable rattling due to metallic parts (the tailpiece is often responsible, or even the truss rod), a gypsy guitar emits two kinds of sound:

  • Variations of air pressure from notes played, coming from the guitar box through the sound hole.

  • Vibrations of the guitar top.


We are not talking here about electric amplification from the strings vibrations with a pickup like a Stimer for example, but our topic is acoustic amplification. We are not either trying in this short presentation to explain how to amplify a guitar using external microphones (Neumann, etc), but our topic is to give some information about sound amplification systems installed on the guitar.
To obtain the best rendering of the acoustic sound signature and quality of your gypsy guitar, you must have the most faithful and natural amplified sound and limit or even avoid completely the Larsen effect to allow for a full volume for the room you are playing in, without restrictions. You have two possible solutions, or even three if you combine solution one with solution two.

  • Condenser type microphone, which is an acoustic to electric transducer or sensor converting sound into an electrical signal. This type of microphone (Audio Technica At 831B and the likes) has pluses and minuses.

Good:
This type of microphone is the closest to the internal ear as it captures the acoustic pressure of air coming out from the guitar body through the sound hole.
It is much more powerful in terms of volume than a piezzo pickup (3 to 10 times as an average).


Bad:
Impossible with a condenser type microphone to get the extreme high notes of the steel strings of the gypsy guitar and poor quality in the highs.
Generates a Larsen effect, as these microphones are still too big.
Playing a steel strings guitar, and most noticeably a gypsy guitar means extreme speed of the played note when picking with the pick. A condenser type microphone is unable to follow properly at these high speeds and the rendering is saturated. A piezzo pickup handles the very fast picked notes properly but has many drawbacks, as we will see later.


The Inghilleri system is composed of two parts, a microchip, which is installed at the sound hole and captures air vibrations from the guitar body and also as an option a piezzo bridge, which captures the vibrations of the guitar top. The Inghilleri microchip sensor, which is very tiny and offers many benefits over a condenser type microphone:

  • The Inghilleri microchip reduces very significantly the risk of Larsen effect.

  • It is capable of tracking the most extreme speed of pick attack on steel strings and gypsy guitars.

  • And, of course, the microchip has the similar pluses of a condenser type microphone: It is a powerful amplification method.


The second optional part of the Inghilleri sound system is the piezzo bridge. Let’s make here a couple remarks:

  • Everybody knows the Bigtone. Poor quality, saturated in the bass notes. The Inghilleri piezzo bridge uses two sensors per string and they are encapsulated in the bridge material. Just plug two guitars in an amp, one with a Bigtone and one with an Inghilleri bridge and you will immediately hear the big difference. You hear the unwanted pick clicks with the Bigtone and not with the Inghilleri bridge and the Inghilleri bridge is not mushy in the bass notes.

  • The vibrations of a guitar top are not the best source of sound for our internal ear. And the place where a piezzo bridge is located on a guitar top is by far not the best place to capture vibrations and sound. Just try with a 20,000$ Neuman microphone to capture the sound of a guitar by placing it where the bridge is. The result will be mediocre.


A good solution is to mix the signal obtained from the air pressure variations of the guitar body from the sound hole with the vibrations from the guitar top. In reality it is difficult to make it properly. Mixing these two kinds of sound signal is like trying to mix oil and water. One takes over from the other. Inghilleri has devised a mix box (Pro Equalizer EQ 130-01) with a "volume", a "highs" and a "lows" knobs which internally optimizes the two kinds of sound sources. Basically the microchip accounts for 90% of the power and the piezzo bridge for 10%. Most guitar players will not hear the difference with the microchip plus bridge but the good players will. The equalizer allows the mixing of the frequencies in a correct and optimized way. The last thing you want to do is to fiddle with the two channels on stage. We need as players to concentrate on our playing or other things of interest in the audience.

A word about the gypsy guitars, and their ability to be amplified.

  • The "grande bouche" D Hole guitars: The acoustic pressure inside the guitar box is unstable and the risk of getting a Larsen effect is more important as the external sound gets into the guitar body much more easily than on an oval hole or round hole guitar (the small oval hole or the F Holes are the best in that respect). Playing a D Hole guitar often means to get the amp behind and trying to find the good angle. Historically, the "grande bouche" was created by Mario Maccaferri to have the resonator work properly. The resonator was a mistake and was eliminated from the guitars but for any reason some luthier find it nice to make D Hole guitars. In terms of acoustic sound quality and amplification problems the "grande bouche" guitars are pains in the ass if I can express it this way.

  • The "petite bouche" oval holes: They create a blowing effect from the guitar body which fights against the external air and prevents it much better to get inside the guitar body, the origin of the Larsen effect.


To install the Inghilleri microchip IMP-130, it is better to install it alongside the strings, between the D and the G strings.

A last word: Patrick Inghilleri has been developing his systems for years and the microchip plus bridge solution with the equalizer box is the ultimate in the sound rendering and the anti Larsen fight. But also Patrick is constantly pushing the envelope and is working on solutions to improve further his products. On the drawing board, in the testing lab and in the field is a multichip butterfly shape system to come out soon. Considering that the present solution today (microchip plus bridge with an equalizer) works beyond any dream of players for sound quality amplification, this new system will rock the world of all demanding players.
