From the vendor

The Lovepedal Les Lius, an overdrive voiced after vintage Fender amps, with a three-way switch for 5E3 Woody, High Power Twin and Master Volume Tchula modes. The post identifies it as another variation of the Electra Distortion (like the Lovepedal COT 50 and Woodrow): a single 2N5088 gain stage with an emitter gain pot, followed by switchable silicon and Schottky clipping diodes and a volume pot. A JFET switched by SW2 shorts the gain pot's emitter path for the boost function.

The JFET switching for the boost function is unnecessary and can be replaced with a simple switch, as the vero layout does (S2, SPST, or DPDT for an LED).
