I split off with a 120 volt duplex outlet from L1 and another from L2
and I have a 240 volt outlet for the amp. Thus both neutral and ground
are needed for the 120 volt duplex outlets. The configuration is very
adequate, legal, and safe for the entire station.

I do not understand the need for three wires plus ground. For a clothes dryer
outlet a neutral is required to get 110VAC from one of the phases to the
neutral. But for amps you only need both phases and a ground. The plugs are
three wire, not four.

I would also suggest using three - #10 with ground as the line from
the breakers to the amp operating position.
Not only a suggestion -- it's the law! Electrical Codes carry the force of law,
and they require that the equipment ground must 1) run with the current
carrying conductors and 2) must be no smaller than the largest conductor.
