RFD Manual
This is the manual page for Leqtique EVR - RFD.

When viewed from the top of the pedal, the right side is the input (unplugging this will turn off the power/battery operation), the left side is the output, the bottom right side is the DC power supply (9V, center negative), and the bottom top of the pedal is the footswitch (true bypass) for turning the effect on/off.
Controls are (Left to Right) Volume, Treble, Gain, and Low-Cut (mini).
MOSFETs, an amplifying element, are semiconductors that were originally developed with the hope of replacing vacuum tubes. Today, they are used in a wide variety of applications across a wide range of fields, but they have not been actively researched in the context of guitar effects.
RFD has taken the infinite possibilities of MOSFETs and used completely original element selection and circuit design to output tube-like compression, violin-like complex overtones, and lustrous sustain.
"Vol" has a wide variable range due to its discrete configuration (the Power IC can be thought of as similar) similar to that of the Roger (EVR), allowing for a very large amount of boost. "Gain" has a smooth compression feel that can already be considered the low-gain OD range, even at the 0 setting, and a glossy midrange. Turning it clockwise adds gain and saturation, giving it the feel of the "Violin Tone" concept of this unit. "Treble" and "Low-Cut" gently shape the upper and lower frequencies of the actual sound to suit your taste, so we recommend setting them to 12 o'clock and adjusting them to suit your environment and preferences.
Operation Voltage: 9V (Even if 18V is accidentally applied for a short period of time, it will not cause any damage, but since the constants are designed to operate at 9V, please be sure to operate it at 9V.)
Current Consumption: 24.9mA (Due to the high current consumption, DC power supply operation is recommended.)
