I so damn love #Roland devices because they work with AA, 9V and other rechargable battery types where ever it's technically possible. I mean there are and were other gear brands doing the same but Roland were early, the #TB303 came out in 1982 and worked with 4AA. It's better for mom nature (setting that you're using rechargables) and also nice for grid indipendent music making.
Und die 303 ist wieder dabei.Muss auch bei Techno.
