Powering
Changing the battery
Changing the standard 9V battery first requires the removal of the four back corner
screws of the pedal. The battery clip is attached to the inside of the back plate - gently
pull the back plate off so as not to strain the connecting wires between the battery clip
and main circuit board. After replacing the battery, carefully place any slack in the con-
necting wires into the box cavity, and replace the back plate with the four screws, taking
care not to pinch the connecting wires.
Using a 9V adapter
Any standard 9V DC negative pin AC adapter for effect pedals can be used to power the
Diamond Drive. The insertion of the AC adapter plug automatically removes the internal
battery from the circuit.
Warranty
Diamond Pedals carry a full five year warranty on registered products - make sure to
send us your warranty card! The warranty is simple - if you have a problem, call us,
send us the pedal if necessary, and we’ll make it right.
Lead
This switches the additional transistor gain circuit in and out of operation. As with the on/off
switch, this switch features true bypass operation with the lead circuit completely removed from
the signal path when off. Operation is indicated with the red LED on. It is important to note
that even with the overall on/off foot switch turned off (but an instrument plugged in), the lead
switch can still be preset to the desired mode of operation, with the red LED still indicating sta-
tus of the lead circuit. This allows a guitarist to visually set the pedal to drive or lead modes prior
to bringing it into the signal path.
Compression
A small unlabeled switch on the front facing edge, past the Warmth and Volume controls, gives
two settings of compression and sustain. The up position of the switch is a more traditional over-
drive setting, with lots of smooth compression, while the down position has a more raw sound.
We’ve found the up position sounds best for Marshall-style mid-gain amplifiers, but the best
