This is both true and not true. The basic filter circiut will have 
the same sound. What makes it sound different is the response time of 
the vactrol. A vactrol is basically an LDR and an LED facing each 
other and encapsulated in black plastic. Since they are put together 
in a non precise manner, not every vactrol will behave the same. So 
the response times will vary, hence the difference from one filter to 
the next. The difference will be marginal and not widely different.

Here is a url with some samples of a vactrol filter and a vactrol 
phase shifter.
