[i think conny DID have a mellotron in his studio at one point,
i can probably dig up some records with pics, but no sign of

there's a quantec room simulator - you don't see them much
anymore - may even be more rare than a publison infernal!
and the BEL delays are some of the original sound replacement
samplers - used secretly by engineers all over - but they
don't like to admit it!]
