Custom Tones, LLC


Mod Options

Available on the Ethos Overdrive, Clean & Clean-Fusion (Preamps and Amps). 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.

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

 FX Loop on Ethos Clean Amp 

The HRM eq is a finely tuned, three band post EQ, inspired by the later models of the most sought after boutique amplifier. Designed to work with both the Ethos Clean and Fusion Channels, the HRM eq extensively expands the tonal pallet of the Ethos. The HRM can be set to get almost flat with a slight hi and lo end emphasis.

The HRM toggle Bypass Switch gets you 100% back to the base tone and allows you to switch back and forth on the fly if desired.
