Jcm 800 Emulator Overdrive PedalPalFx. PAL800 JCM Emulator Overdrive. This design is the first version of our 800 series, known to our customers as the “Silver Version”. With the PAL800 JCM Emulator now you will have the tone of an era at your feet, this 100% handmade pedal (one by one) uses the same circuit schematic that you will find in the most famous British Amps from the 80’s, using especially selected transistors instead of vacuum tubes.
