KarDiaN | Serotonin 5th Limited Edition | C10H12N2O | Overdrive & Boost based on TS5 | Made in Japan

KarDiaN, a pedal brand born in 2017, is now celebrating its 5th anniversary. This year, we will produce a pedal named after the number "5," which is the number of the anniversary. What comes to mind when you think of the number "5"?

Of course, there is only the "Ibanez TS5 Tube Screamer."

So, in celebration of "KarDiaN 5th Anniversary," we are pleased to reconstruct this lovely pedal in black and green.KarDiaN has released "Serotonin", which was originally developed as a reference for Tube Screamer.This time, based on this design, Kitada interpreted the actual "Ibanez TS5 Tube Screamer" that he owns and created his original design "Serotonin 5th".It is an extreme high-gain pedal that pushes the high-gain Tube Screamer, a feature of the TS5, even further, as well as a tone stack with 2 EQs, which the TS5 does not have.

Serotonin 5th", produced in honour of the 5th anniversary, will be released in a limited edition of 150 units worldwide.

"Serotonin 5th" has special attention from the parts. In particular, it is no exaggeration to say that the fact that we were able to secure 150 units of Toshiba's TA75558P op-amp, which was also used in the actual device, was the catalyst for the creation of this pedal.

The op-amp's fuzz-like graininess when turned up produces a distortion that is typical of the TS5. In addition, we used the ERO MKP1845 from Ernst Lederstein of Germany to bring the gain point to a much higher level than the normal TS5 and Serotonin. This allowed us to create a sound with a strong core flavour while suppressing unnecessary high and low frequencies when the gain was increased. In addition, the Isahaya 2SK2880 transistor used as a buffer produces a characteristic sound with strong midrange stickiness.

Electrolytic capacitors around the power supply were also changed to 100uF KEMET A750 series to provide noise suppression corresponding to high gain.
