S•500 E prototype-3

The S•500 E prototype checks in with the big boss. The white mini-toggle switch controls the G&L micro-preamp (off/on/on-bright) and the red one is the S•500 pickup expander switch. With the expander toggle switch on, positions 1 and 5 are neck+bridge, positions 2 and 4 are all 3 pickups. Position 3 is middle pickup only whether expander is on or off.
