Clean-Fusion Preamp with FX Loop

 TLE vs Classic Demo by Tim Lerch

The FX Loop mod was developed after great customer demand. It can be installed in all Ethos pedals.  Locating the FX Loop in the preamp section allows your effects to be heard via the normal and speak sim outputs, as well as the speaker out. This configuration can be very useful when running a feed from the speak sim to the PA/board while listening via the amps local speaker. The FX Loop is within the Ethos, so when you bypass the unit, the effects will be bypassed as well.

  • Loop Type: Serial
  • Input Impedance: 1 Megohm
  • Output Impedance: 1 kohm

The TLE/Classic Switch allows you to switch between the Classic Mode and the TLE (Tighter Low End) Mode. Available on the Ethos Overdrive Preamp and Ethos Overdrive Amp.
