"This unit is a 2601 Rev3, which is the very last revision of the 2600. It comes with the 3620 keyboard, which is duophonic. The last 1,000 units made were 2601s and only the last 100 or so were Rev3. They are quite rare. This is important, because the Rev3s did not have potted submodules, so they can be worked on. The rev3s were mechanically superior to the earlier models. Some people do not like the later filter as much, but that is an $99.00 upgrade from CMS. I like the sonics on this one, I have never found it to be dull or noisy, so I have never modded it.
The best 2600 to look for?
Probably the best course would be to find a late model (2601) and get the audio upgraded here at CMS. The earlier units do sound better from the factory, but the numerous mechanical problems can add up to a hefty repair bill especially if the 2600 in question, has been exposed to moisture for long periods.
Note: I couldn't use the "Click for more" link on this one as it breaks the videos.
