Ibanez ST9 Super Tube Screamer Vintage JRC4558D 1984 Green Sparkle

When we talk about choice of good guitar tones , it usually went from Fender twin clean to fuzz face in a Marshall amp, while these options were way too expensive for teenagers. Even in our favourite records , that creamy tone we all know and like now, was totally absent. Of course, it was always possible to roll-off our guitar volume knob when engaged in a fuzz pedal to obtain something more coherent for rhythm—and then of course go full volume for fire-breathing solo.

As far as I can remember, the first time I heard this tone was from a Stevie Ray Vaughan track and it changed everything. While Boss OD-1 was already there when the Ibanez ts came out, it somehow flew under the radar.

For many of us, when we see a green pedal, we immediately think of an overdrive. And not without reason. The green pedal is one of the most iconic overdrives out there, and it comes in many forms. This article is an attempt att describing the various forms it has taken over the years, from its humble beginnings to present day. A few used the JRC instead.

The pots are different from the ones in the later pedals they are the open design, rather than enclosed , but aside from those you could easily turn a far cheaper TS-9 into an

The pedal has a characteristic mid-boosted tone popular with blues, rock and metal players. The “legendary” Tube Screamer has been used by countless guitarists to create their signature sound, and is one of the most successful, widely copied, and “modded” overdrive pedals in the history of the electric guitar. The Tube Screamer has a drive knob, a tone knob, and a level knob.

The drive knob adjusts gain, the tone knob adjusts treble and the level knob adjusts the output volume of the pedal. The pedal is used to try to mimic the sound of a vintage tube amplifier. The classic Tube Screamer sound includes a “mid-hump”, which means that the circuit accentuates frequencies between the bass and treble ranges mid-frequencies.

Dating an original ts used by Ibanez, and some aficionados would only swear by the Malaysia RCP from T.I. or Japan Radio Company JRCD.

I thought the maximum current an op-amp can supply is the ‘short-circuit current’ – which I believe is approx. I think the simulator is not accurately calculating the voltage drop between stages, or at least that is my best guess. Originally they had no pre-amplifier in the base and the high impedence crystal element was a good match for the high impedence audio inputs of the tube rigs of the era. In cases such as this, you may need to place small capacitors pF , across GTABLES set up as ideal diodes or current limits and actual diode models.

Moreover, for TL in 4sum circuit and 9 V battery supply decreased by protection diode voltage drop — check the schematic , the maximum input voltage is around 8,3 V. To power a portable version, the best solution is to use two 9V “transistor” batteries wired in series, in order to obtain a 18V supply: the results will be worth the increased expense. Here is a simple but powerful, stable and efficient schematic diagram for a W modified sine wave inverter circuit.

The circuit is divided into two parts — the op-amp based pre-amplifier and the Baxandall tone control circuitry. Both resistors R3 and R4 are set in the class A mode, to be the bias current to the base of transistors Q1, Q2. I recommend a TL or the as a good starting point, but if you use a socket for the opamp, the chip can be swapped to test a variety of sounds and capabilities. Things like replacing a opamp with a TL is something that will not only add noise but also degrade audio quality.

After opening it up, you can see that it has the jrcd chip and the original maxon How to date an original ibanez ts 9 tube screamer by scott sill youtube.

In fact, Maxon was the OEM original equipment manufacturer for Ibanez and actually made both the Ibanez pedals as well as its own under the Maxon name. Thankfully though, modifications were easy enough to perform to turn the TS-9 reissue into a genuine TS and many offer that service today. As tone-lovers, we were anxious to take the OD for test spin.

The unit houses one 9-volt battery accessible by removing four screws on the base of the unit, which itself is approximately the same size as a typical MXR effect pedal. An AC adapter jack is provided as well as individual quarter inch input and output jacks. A big selling point to the OD is its inclusion of the famous JRCD chip, the chip used in the original designs. In comparison, the TS-9 reissue incorporates a chip made by Toshiba that hinders the smoothness of its own tone.

It will be interesting to see how the recent-issue JRCD chips sound in this circuit compared to earlier production varieties.. The manual that accompanies the OD is particularly useful as it includes not only basic operational directions, but sample settings also for use with both single and humbucking-equipped guitars.

Free shipping. I only use overdrive pedals to shape distortion and amp drives for high gain. I connected it before my mxr pedal and it made it sound from good to awesome. I have many name brand overdrive and this is just as good as some and better than others. I also love the housing and art work, it’s my new go to pedal. Excellent guitar pedal! I was a little hesitant to buy this one, regardless of the positive reviews, because another Caline overdrive pedal I bought a couple of years ago makes a loud pop whenever I switch it on.

But this one doesn’t do that. It sounds very similar to my Ibanez TS-9 pedal in that position.
