The OxyTone FtoE is a dual-channel pedal featuring a preamp inspired by the Fender® Champ 57 (5F1 / 5E1), equipped with a volume knob and an "F to E" control. The 5E1 model achieves saturation more quickly than the 5F1, which maintains a brighter tone at higher volumes; thus, the "F to E" control allows you to tweak the saturation level between the two models. Additionally, it includes a clear low-gain overdrive derived from the renowned OxyDrive, slightly adjusted for seamless integration with the preamp.
