Operational Notes
The Oldfield Dual 40 amplifier offers the player a lot of functionality and at first glance can appear to be
somewhat complicated to operate. A little experimentation goes a long way to understanding all the
tones hidden inside your Dual 40 so don’t be afraid to flip some switches and twist some dials to
broaden your understanding.
