Kleinanzeigen Heroes: Ibanez JD9 Jet Driver

Favorable workers, unjustified Underdogs, over-the-top Youngtimers and forgotten Exotics: The “Kleinanzeigen Heroes” introduces the secret tips of the trade market that love maximum “Bang for the Buck”.

Who can use an effects pedal on the radar of their own flight? A competent Antwort connected to Ibanez JD9 is an insurer of the distribution of the tieffliegens that are not perfect, but have been given a name, but the Jets player …

A lot of information has been found on the internet about the Jet-Driver-Pedal, which was released in 2011 and 2016 in the part of the “9 Series”. Damals has never used a new Tube Screamer (TS9, TS9B, TS9DX, TS808 and TS808HW), but other pedals are nice: CS9 Stereo Chorus, FL9 Flanger, AD9 Analog Delay, BB9 Booster and the JD9 Jet Driver.

While JD9 was at work and part of the printing press acted as the flowering of the Tube-Screamer-Derivative, it is so delightful in painting, but the previous Tube-Screamer-Palette eigentlich alles, was the man of the Theme from the closet.

We are an intensive and with a technical knowledge towards the JD9 version, which we can recognize, that the pedal is another mainstream pedal, hidden features and secrets in its birth, while now there are some exclusive messages.

TS FROM HELL OR KING OF TONE?

In Foren it is also known that JD9 is now a higher version of the TS9, a “Tube Screamer from Hell!” Was an Irrtum! Wobei: Ibanez itself has implemented this new feature, in that the JD9 has a new tuning, in the aber of the Tube-Screamer-typical bass-cut at 720 Hz. Kein Wunder has sold the Pedal people here a Tube Screamer with HiGain-Potential boost. This can give the JD9 a great new experience!

How to hear a crazy Bernd Meiser: “I am JD9 which has an inverting OP amplifier control with overdrive effect. In TS9 and signals 1001, derivatives that use a non-inverting OP-Beschaltung, or ‘Electrometer’-Beschaltung, have been generated. Here there is no compression whatsoever on a signal limitation with z.

German genauer of the JD9 the Endstufensättigungs-Simulation and (see the blue Kurve in Abb.1) and steht damn in a Reihe with solch illustrate Pedals who z. B. from Xotic RC Booster, from Marshall Bluesbreaker or from Analogman King of Tone. Nicht die schlechstenen Referenzen …

The inverting OP scaling of JD9 is the TS9 in Sachen Endstufensättigung-Simulation tatsächlichlich weit überlegen, here is the pure non-linearity of the diodes in the Übertragungsfunction zum Tragen kommt. Exceeding expectations is now no longer possible, but the man cannot go further than a simple Si-Diode. This Si-Diode was built around 1970 and used in one of the simulations – which I believe is MXR Distortion+.

The functional functionality and these Si-Diodes were small, robust and affordable. If there is an orderly operation and a generated sound, man is utilized with his Sankt-Nimmerleins-Tag. Now there are some new Freaks experimenting with others, but there are still no crazy things… with the Ausnahme of the selected Z-Diode over time. Those who prefer to be modest, if you live in a TS-Schaltkreis, would rather fly in an inverterende OP-Schaltkreis.

There are no technicians who have the insignificant properties of that switching and their tolle knowledge line – a man will think a guitarist or not be a guitarist himself, a quality that a successful Break-down-Bereichs z. B. for a gelungen Endstufen-Simulation would acknowledge. If you go one step further, the Z-Dioden uses a reverse switching function.

These may not be great with the filter functions on the board, but soft drinks have a fine effect on the airspace they use. The Tech21 Blonde is such that there are only a few drive pedals in the Z-diodes since they have been welded into air.

JET = ÜBERFLIEGER

This Z-Diode also has the ability to fly over in a reverse OP-Schaltkreis as the JD9 would become. With a targeted filter configuration of C5` and a custom tone filter with the JD9 a good sound machine, which was in the final simulation program, the TS9 was another target.

If the installation of the Z-Diode no longer works (see the green curve in Abb.1), it is obvious that this is not the case with the leakage (in the flushing position) of the Si-Diode in the open, without any problem. here the knowledge of the characteristic of one of the best results is over! It is not clear that the restoration of the positive mark of the Z-Diode in an inverting OP-beschaltung useful.

Aber gut – Ibanez was never a fact, he could make his own choice with JD9 during the Tat time.

DO THE MOD

Vorab: The described mods are relatively small, the JD9 has a good “Leiterbahnen” layout and a board!

Will man at 9V-Geräten good Ergebnisse, muss man with sehr small Z-spannungen work, wie z. B. 2,4V, 500mW. Please refer to the following information about the 9V Spannung sogenannte ‚rail-to-rail’ – Types of connection found. After the two anti-parallel Si-Diodes from the Overdrive section of JD9 (IC1_A, like Abb.2) were installed, the two Z-Diodes were placed in an anti-serial (!) direction.

Damit generates a feine, and the 3V signal is transmitted. If humans leave the rest of the JD9 scale, the signal will increase by a factor of 6. If you have an umbau of the work Tiefpasses (R8 + C5), it is not possible to use the desired frequency to generate the Abschwächung used. The original filter is from punks A and B through the new filter from punks A` and B`. Das C5` can have a starting value of 220nF after it is reduced in size; 100nF to 68nF is fine. So the work installing the Grenzfrequenz (720Hz) is high and the Jet Driver is used with the nasal TS9-Grundton. An amplification effect is lower than the R9 (27kOhm) in the gegenkopplung of IC2_A settings.

Fazit: The new switching of the JD9 Jet Driver does not work with the optimal diode, but with a mod potential, the pedal is light, one in the sitting position ultimately becomes a simulation!”

Nor is there a problem with the graphics in Abb.1: A different approach to progress, that Bernd Meiser mathematically bears the green JD9-over-the-road knowledge line with Z-Diode, which combines this optically with the other two graphs in the working area; the Z-Kennlinie hat normally 3V Peak.

INFO & PREISE

JD9 Jet Driver, vermutlich nor fertigt in Japan, were between 200 and 350 Euro Angeboten und lie wie Blei in de Portals, wat man Chinese bereits für spätere costs 50 euros can obtain. These different small investments are especially important if you use the pedal described above. Changes may take longer. Damit der Jet now endlich zum Überflieger became kann!
