Where Are They Now?










If you are the proud owner of a Polymoog or have owned one in the past Dubsounds would be delighted to hear from you. We have an inventory of current Polymoog owners on the site with information such as serial numbers, date of manufacture (found inside the case), location and historical details such as previous owners, which will be a continual work in progress. Simply email us with as much information as you have and put yourself on the map.




Additional information and proof reading: Colin Vincent and Jordan Gibson respectively. Your patience and expertise is greatly valued.
