Features

Leqtique is a brand started by Shun Nokina in pursuit of "Reality" based on his experience at Shun Nokina Design etc.
It features the same elite components as SND and a thoroughly handmade construction, offering a different world that goes far beyond "cost performance."

The production of this product uses not only top-grade modern components such as PRP Resistors, OS-Cons, and Wonder "Signature" Solder in a machined aluminum case, but also components with a so-called "antique" feel such as Allen Bradley Resistors and Vintage MKT Capacitors.

The Caeruleum Light Drive HD (CLHD) is an effects pedal that was first announced at Winter NAMM in 2012 and has undergone repeated intermittent reconstruction over a long period of time, and is finally complete after being designed to deliver uncompromising sound in all four roles: Clean or Gain Booster/Buffer/Preamp/Low Gain OD.
The basic idea is to use the Volume and Gain controls, which have the same operability as a typical overdrive pedal, as a foundation, and then use the special control in the middle called "Definition" to create a wide variety of sounds.
Turning this control clockwise blurs the contours of the sound without reducing its resolution.
From a circuit and auditory perspective, it creates a sense of compression, a rounded high end, a smoother, fatter tone, etc.
The ultimate purpose of this control is to adjust every factor simultaneously in a musical and intuitive way, so if you think of it as a general tone control for cutting high frequencies, it's a bit simplified from the actual effect it has, but it's easy to understand.
As for specific uses, firstly, as a Clean Booster, by setting the Definition and Gain to 0% and then raising the volume, it functions as an ultra-high-fidelity, transparent booster, due to the internal boost circuit running the ultra-HiFi op-amp LT1028 at around 30V and the brass casing capacitor hidden inside.
In this case, if you feel that more harmonics have been added than to the original sound and that they are unnecessary, you can slowly cut the Definition to around 50% to obtain a more natural sound that is closer to the original sound.
Additionally, by turning up the Gain control as a Gain Booster and turning the Definition control above 50% you can get the smooth compression and natural high end cut that comes from the vintage 1N270.
Try using it before and after your favorite drive pedal, especially when playing solos.

As a buffer and preamp, the Gain is basically fixed at 0 and the Volume is fixed at around 50% to reproduce the original sound, and the Definition control can be used to make the sound closer to the original or to add a smoother flavor.
The signal is then converted to low impedance.

Finally, as a Low Gain Overdrive, in this case you can basically create the base of the sound with the Volume and Gain, and then adjust the Definition control from a crisp 0% setting which is perfect for cutting, to 100% which produces a smooth TS-like sound, depending on your preference and purpose.
One of the CLHD's greatest strengths is that no matter what setting you use, it responds extremely sensitively to the guitar volume and can return to a full-range, fat, clean sound.

Operation Voltage: 9V ONLY (12V or higher will destroy the internal IC and cause it to malfunction, so please use a 9V rated adapter or battery.) Current Consumption: approx 45mA (It consumes a large current due to the internal boost circuit, but it can also operate on 4V, so it has a longer operating time even with batteries than general high-current driven effects pedals.)
