Very few items have serial numbers. Some older devices like the Sound Studios 1/1X and the last limited special edition of the ODR-1 Ltd. Most numbers, e.g. on base plates, indicate versions or are EAN numbers on the packaging.
Here we have set up a separate section under History. Here you will find a lot of interesting milestones.
A limited number of 2000 pieces were built and sold worldwide. The pedal differs only visually from the ODR-1 (Bass Cut) but has a certificate and an individual edition number.
