INTRODUCTION
The Heliosphere Dual Distortion is based on the Stamps Amplification Drive-O-Matic, a very rare
distortion pedal built by Robert Stamps of The Amp Shop in Los Angeles in the mid-1990s long before
boutique pedals were mainstream. Despite the relative obscurity, the Drive-O-Matic was used by a few
professional musicians such as Bonnie Raitt and Rick Vito. It was
The Drive-O-Matic is clearly derived from the
but several part value changes for a different voicing. The major feature addition is the channel-
switching, in which a second footswitch engages an alternate drive knob and also switches out a filter
that changes the tone somewhat.
Robert Stamps only made one other pedal under the Stamps Amplification name, a higher-gain variant
called the Drive-O-Matic XL. This version removes the diode switch in favor of an added "Saturation"
control (which may control the diodes directly), and presumably has some circuit tweaks to increase the
gain based on the description. The Drive-O-Matic XL is extremely rare and has not yet been traced, but
if we ever come across one then we'll open it up and see what's different about it.
The Heliosphere is an exact clone of the Drive-O-Matic based on our trace. Full details are available in
the tracing journal. We do recommend some small changes to the base circuit to make it more versatile,
which are described in the build notes.
USAGE
The Heliosphere has four knobs, one toggle and one extra stomp switch:
• Drive 1 sets the gain of the first channel.
• Drive 2 sets the gain of the second channel.
• Presence cuts treble after the clipping stage.
• Output sets the overall volume level of the output.
• Clipping (toggle) selects between silicon diodes, LEDs, or no clipping.
• Channel (stomp switch) selects between Drive 1 and Drive 2 settings. An LED shows which knob is
active.
