New Opto Tremolo In Development

After countless modifications and testing more than a dozen of different resistive optoisolators I am finally at a point, where my new Vactrol-based opto tremolo circuit sounds just awesome. I already sent a first prototype to Styrian guitar player “Sir” Oliver Mally, who confirmed my assessment: this is something big. I’m really looking forward to bringing this little sound monster to market in the next weeks!
