The Brown Betty pedal is a hybrid design that combines the features of the Thermionic Distortion and Dirty Sanchez pedals. It is based on the Friedman BE-OD and Dirty Shirley models. The pedal features several controls for shaping the tone. The Bass control adjusts the bass frequencies, while the Treble control adjusts the treble frequencies. The Presence control is used to shape the upper mid-range frequencies. The Volume control adjusts the overall output volume of the pedal. The Mid control allows you to shape the midrange frequencies, and the Gain control adjusts the amount of gain in the signal. Finally, the Tight control is used to shape the low-end frequencies before the gain stage.
