Now that's a pretty face.
The Lovepedal Babyface Tremolo guitar effects pedal is a full-featured tremolo pedal in a mini enclosure that has 3 switchable waveforms. The speed knob on the outside gives the tremolo pedal a nice range of speed from very slow to super-fast, much faster than what many modern tremolo pedals offer. The internal volume control has boosting capabilities, which modulates the volume of your signal with regard to amplification.
Setting the dial far left gives you the most common wave you hear in many old blackface or brownface amplifiers. Typically called a sine wave, the top of the waveform is smooth and subtle. You can increase or decrease the depth in any setting with the internal depth and volume controls. The tremolo pedal's middle setting is not quite a full square wave chop but a saw tooth waveform almost a mixture of the sine and square wave. The far right setting provides the full-on square wave or what Lovepedal refers to as "Chop City." With absolutely no bleed, this waveform is excellent with fuzz, overdrive, and/or distortion for a full-on choppy, effected sound.
The tremolo guitar pedal's external speed control sets the speed of the waveform. The internal depth varies the ratio between effected and dry signal. The Lovepedal tremolo's internal volume is the master volume control with boosting function. Finally, the external stompswitch turns effect on or off.
