This may be best suited for Dieter.
As I'm not certain how the vactrols compare-- I could look... and meant to
but now the system is on... and I could only tell you if they're the same as
the 101-2. But the ones Doepfer uses are different the VTL5C Series from
PerkinElmer that Plan B and most others use.
It would be great to know how they are related, and if they are
interchangeable --any potential benefit or difference replacing with another
Vactrol--assuming there is an equivalent
I love the 101-2 and the M13-- but they are very different, not sure if the
Vactrol used contributes much to that....

(and just in case I mislead or someone reads this later, the 125 has NO
vactrols but still is very nice, and I think worth keeping even with the
great 101-3 around)
best,
phil
