Accordionists asked for it and Harmonik made it possible!

The FS (Feedback Suppression) model is designed for those who want to combine the pure accordion sound with loud volumes without having to worry about feedback.

The main function of this model is the automatic suppression of feedback: the FS function eliminates those remaining frequencies with a simple click, and above all without distorting the timbre. It sounds like magic, but it's actually pure technology. This way, the accordionist can use extremely high volumes on stage without being dependent on the technician and the sound equipment.

Another new feature of these models is the ease with which you can switch digitally between mono and stereo modes: with just one click of two buttons simultaneously, without having to open the accordion grill. Extremely fast and practical.

And that's not all! To provide even more fidelity, we've added an external microphone emulation to the bass sound, resulting in an extremely natural sound. It's like having studio sound on stage!
