It was meant as a birthday present for my son. He plays guitars.
After he has unboxed the unit, there was almost no wet signal present. Went to the product page at Thomann and started the chat. After just one forwarding in conversation, I got an expert on chat and we fixed it together. Thanks Thomann.
I was brave enough to open the cartridge cover to realise that head was not adjusted as it should be.
With this pedal-instrument you achieve a unique sound of tape echo. You may compare it to the digital or bbd siblings, but it is likely just more inspiring and, it adds a probability game to your play.
