The original Waldorf Mugs
Left to right:
Waldorf Mug version 1.0, version 1.5 and version 2.0
The 16 voice analog filter board of the WAVE wasn't included!
Notice the different main colour being a bit to bright on version 1.5
And the version 2.0 printing being white.
The little defect on my version 1.0 is a custom modification.
Waldorf never offered an upgrade kit or a trade in option for older version.
