Welcome! Thank you for entering the realm of Pigtronix. Your OFO is a professional quality, 100% analog distortion pedal that features three original Pigtronix effects. The “Overdrive” and “Fuzz” effects in this pedal are wired in parallel, allowing you to blend two separate distortion sounds for a remarkable range of thick yet articulate sounds. There is also a frequency doubling, “Octava” circuit, wired in series before the Overdrive and Fuzz.
Anatomy of the OFO The Interface: Jacks 1. IN – Effect Input - Plug instrument in here 2. DC POWER 9-15VOLTS – Power input. We strongly recommend that you use only the 15-Volt, negative tip power supply that came with your Pigtronix OFO. Using the wrong power supply could result in a damaged pedal. *note: The OFO is able to run on 9-Volts, however, for best performance please just use 15-Volts at all times. 3. CLEAN – Your clean signal is always present at this jack. When the unit is powered up.
Overdrive Controls 5. LEVEL – This dial sets the output volume of the Overdrive. 6. GAIN – This dial sets the amount of gain in the Overdrive. Since the Pigtronix Overdrive is touch sensitive, you can set the gain control higher than you might on a different pedal and still achieve soft distortion by playing softly. With the gain set all the way counter-clockwise, the Overdrive circuit will act as a clean booster. 7. TONE – This dial sets the cutoff frequency for the Overdrive.
Getting Started Basic Hook Up 1. Unpack your OFO and place it on a flat, stable surface. 2. Make sure you are using the 15-Volt DC (negative center) power supply that came with your Pigtronix OFO. The OFO will work with 9 OR 12 Volts DC (negative center) but this is not recommended. Plug the power cord into the 9-15VDC jack on the back of the OFO and then plug the power adaptor into an electrical socket. The OFO is now powered up.
Guided Tour The following steps guide you through the sonic palette of OFO and show you how to get at the range of tones that it has to offer. 1. Set all of the OFO’s controls to the 3:00 position with all three LEDs turned off. The SHAPE control should be set to #1. Make sure the volume knob on your guitar is all the way up and that your amp is turned on and set to a reasonable playing volume. Overdrive 2. Turn on the Overdrive, the blue LED should light up.
10. Now try some power chords using the bridge pickup. 11. Now, play an open E major chord. The Octava will remain stable with major chords. Next, play an open E minor chord. As you will quickly notice, the Octava becomes unstable with some chords and sonic carnage sets in. 12. Explore the range of the Octava TONE control. Notice how as you play higher up on the neck, the octave up sound becomes more pronounced.
