Hola,
here is some Polivoks + MB6582 live action :) (SIDs start at 00:50).
That filter nicely increases the rawness of the SID sounds, a highly recommended build and quite cheap (google bareille polivoks schematics!).
(also some flying close to the limits in the bavarian alps, what a fun day it was :D)
Many greets and thanks for listening!
Peter
