. The external pedal’s input is connected to the KGB Loop’s “LP SEND” jack and its output to the “LP RTN” jack.
The Variable Input Impedance works best with passive instruments (guitar / bass) and allows tone-sculpting with or without the LOOP circuit engaged. The footswitch provides a true bypass function that offers two operating modes, controlled by the “Bypass Mode” switch.
In Mode A, the footswitch alternates between full bypass and the complete KGB Loop signal chain in including an external pedal. In this mode, please ensure the external pedal is switched on. This allows the complete bypass of the KGB Loop and the external pedal with just the KGB Loop’s switch. This is great for use with older ‘tone suck’ pedals (older Fuzz Faces, early Big Muff’s, etc).
In Mode B, the footswitch alternates between the external pedal alone and the external pedal with KGB Loop features added around it. This allows the external pedal to be fully used as normal. To achieve full bypass in Mode B, the external pedal’s on/off footswitch must be used.
