The EMMA Electronic ReezaFRATzitz 2 is a unique overdrive/distortion pedal designed to emulate tube amp distortion, offering a wide gain range from bluesy to rock. It features a bias control to adjust the harmonic structure, from smoother Vox AC30 tones (Class A) to classic Marshall Amp tones (Class B). Additional controls for Level, Gain, and tone shaping let you fine-tune your sound.
