This system is amazing! It basically allows you to hook up a load of pedals and either switch them via MIDI, either from the Ground Control or a sequencer.
It has a built-in high-impedance buffer / driver which ensures that a healthy signal reaches the pedals.
I have two of these units, both in lovely condition.
Both GCX units and both Ground Control units come with power supplies.
PRICE: £300.00 (was
£400.00) plus £20.00 p&p to UK mainland. Cost of shipping includes insurance.
