Stone Deaf PDF-1X Instruction Manual

Its been 10 years since we presented our first offering the PDF-1 to
the world and weve decided by popular demand to bring it back
but to keep the features of the PDF-2 as well as add some new
things to the circuit.

As one of the lucky few we present to you the Ltd Edition PDF-1X.
This is a combination of the original PDF-1 and PDF-2 with 800
units being manufactured world wide.x

The PDF-1X takes the best bits of both units and combines them for
a set and forget pedal board staple as well as a studio recording
tool to bring life to dead tone and bland amps.

As many of you already know, if you have owned a PDF-2 or PDF-1
its lacked a volume knob which we have added. Weve also tucked
away the gain knob to an internal trim pot which is a set and forget
feature. The volume knob however opens up a variety of tonal
options on both channels being able to drive clean amps into
overdrive or manage tone at lower levels.

The soft clipping circuit is set to PDF-1 territory from manufacture
so adjust accordingly to get PDF-2 gain by using the internal gain
trim pot.

The PDF-1X is our most versatile offering combining boost, cut,
Parametric EQ, Distortion, Overdrive and Fuzz Tones as well as
Expression. It will also work on bass, synth or other instruments
should you wish to experiment so it is quite possibly one of the
most versatile analog pedals on the market today.

channel of an amp into distortion and clipping with the option
of additional clipping from the gain circuit.

• (IMPORTANT: ADJUSTABLE GAIN IS AVAILABLE WITH THE
INTERNAL TRIM POT. UNSCREW THE CHASSIS BASE AND SET
AND FORGET. THIS WILL CAUSE OSCILLATION AND DISTOR­TION COMPRESSION WHEN TOO HIGH!!!)
The gain is set to original PDF-1 settings but can be adjusted
with a small screwdriver to increase to PDF-2 and beyond.

Please note unity gain will move with different frequency
positions and you need to adjust all controls to suit. Ideal
position is to place at the end of your overdrive / fuzz chain and
before modulation. It will add additional noise on the gain
circuit and by increasing the volume in your effects chain. Id
recommend our noise-gate to eliminate this.
