Regarding the G6 Cabinet:
Let's face it - the fact that Doepfer offers a shielded housing with
built in psu for their modules like the G6 is a great benefit to all
of us. You can always go cheaper - but it is great to be able to use
systems in studios with TV sets and other RF broadcasters without
moving the synth around like a Fender Stratocaster - which is typical
of "open backed" modular systems.
In most music studios nowadays, the modular is the ONLY devise without
an RF-broadcasting microprocessor, so this is a consideration.
If you were to try to fabricate your own shielded case for a MOTM
system, you would very quickly realize that what Doepfer is offering
is very affordable!
(I fabricated my own case for a Wiard 300 system - I won't even
mention what that cost!)
