1978 Gibson RD Artist bass
switch detailsThe RD Artist bass controls are not straightforward. The top switch - or trick switch, has three positions: compression/expansion, neutral and bright/lead mode. The switch below is the pickup selector. The compression only affects the neck pickup, whilst expansion only affects the bridge pickup.
