EXP input:

Can be used to externally control the pedal's control knob

or sample rate knob with an expression pedal or CV source.

When something is connected to the exp input, the control

or sample rate knobs can be used to define the max range

of the exp input.

Most commercially available expression pedals using a TRS

plug should work. The value is not really critical, although I

would not go lower than 10k.

You need to use 1/4 inch TRS (Stereo) plugs and cables. NO

MONO PLUGS OR CABLES! These will short out the

voltage regulators inside the pedal and possibly damage it.

Layout of the TRS connections:

- tip: controlling pin

- ring: 3.3V supply voltage

- sleeve : ground

If you really know what you are doing you can actually use a

control voltage instead of a resistance based controller but

you need to consider the connections and never exceed

3.3V.

If you have any doubt when deciding what to connect to the

expression input please send me an email and I will verify

that everything is safe.

Power Supply:

The power supply needs to be 9V/100mA center negative

like the com- monly used guitar pedal power supplies:

Make sure the polarity and voltage of your power supply is

correct or it will damage the pedal. Do NOT run at higher

voltages.

As the pedal uses a digital processor operating at high

frequencies, you may hear some noise if you use it on the

same power supply with other pedals (daisy chained) even

when it is bypassed.The noise can bleed through the power

supply into the other pedal's signal. This is normal for such

devices. It might not be the case in your particular setup but

if you notice that, I would suggest using an isolated power

supply.
