dpFX Pedals - Dual Impedance Changer (input & output)

"dpFX Pedals" builds handmade and custom effects (dpeffects.com). All products are serial numbered.

This is the Dual Impedance Changer, two circuits of our classic impedance changer (A, B) housed in one enclosure.
The Impedance Changer helps you adjust the way that your instrument interacts with the pedals that follow or even change the way your effects interact with each other. It is suitable for bass, guitar or any other instrument with similar pickups.
It's actually a sort of variable "buffer". Two potentiometers give you the ability to select the input & output impedance of the circuit.

A lot of effects that are available in the market (e.g. vintage designs, older fuzzes, treble boosters, circuits with germanium transistors etc)  have a quite low input impedance and that's what gives them their distinctive character, especially if you connect your instrument directly to their input. But this character and their "behavior" changes (often getting worse) if you change your instrument (e.g. when going from passive to active) or if you have a non-true-bypass, buffered pedal connected in front of it. That's where the Impedance Changer can offer you a solution.

With this pedal you can experiment and see how every pedal responds with different impedance values. The IN-knob (1M~1k) changes the way the signal is picked up from the input and the OUT-knob (0~220k) changes the way the signal is picked up by the next pedal in the chain.

>>> You will be amazed on how lot's of effects, especially the ones that introduce distortion, change their character and their sound as you vary the output impedance of this pedal. <<<

Each footswitch (A,B) allows you to completely bypass the respective Impedance Changer circuit.

> Quick Tips:

• Depending on the instrument (or pedal) you connect to the INPUT of the Impedance Changer you may notice a different behavior of the IN-knob, usually being more effective after the “12:00” position.
• As the IN-knob gets closer to the 1k position a volume drop is to be expected.
• When IN-knob is set at “1M” and OUT-knob at “0ohm” the pedal works as a buffer. (High input impedance, Low output impedance)
• When you connect a pedal to the OUTPUT of the Impedance Changer, the lower the pedal’s input impedance is the more drastic the OUT-knob will be.
