The vintage odd/filter fuzzy distortion pedal to enhance your guitar tone.

Wellenmonster Expression is our interpretation of the legendary Systech Harmonic Energizer. It can be used as a booster, filter or as a static/cocked wah and has a huge amount of gain. You can easily control the huge amount of gain and distortion with the Gain knob and we designed in a Volume knob in contrast to the original version. The Frequency and the Q-Factor allows full control of the rich harmonics the pedal creates. Wellenmonster enriches your sound from fuzzy low thick tones over nicely boosted mid tones, static/cocked wah sound to really high gnarly twang tones, that scares your neighbours eardrums. And with the expression input it is even possible to get an very interesting WahWah out of your lame expression pedal. Some customers use it with vintage organs too, it sounds awesome!
