Noise/Hum
Power source: Ensure that the proper power supply is being used.
Near noise source: Move pedal away from power supplies and other equipment.
Other equipment: Remove other effects from signal chain; see if noise persists.
Bad cables: Swap out audio cables.
USB ground loop: When connected to a computer using a USB cable, noise can appear in the audio
signal. This usually results from ground loop noise due to the EQ2 and computer running on separate
power supplies. In the case of laptops, disconnecting the computer's power supply and running it on
a battery can often mitigate the noise. External display monitors are often the primary source of
noise, and powering down monitors can also resolve noise issues.
Ground loop with amp: Make sure your EQ2 is running on the same power mains circuit as your
guitar amplifier.

Frequently Asked Questions

What kind of instruments can I connect to the EQ2's inputs?
The EQ2's audio inputs are high impedance (~ 1 MΩ) and they can accept high impedance signal
sources like guitars/basses with passive pickups, as well as low impedance sources like line-level
audio circuits, guitars/basses with active pickups, electronic keyboards, or mixer outputs. The input
circuit can handle signals ranging up to 6.0 Volts, peak-to-peak.
Can I power the EQ2 directly over USB, without using the 9 Volt supply?
No. USB provides 5 Volts, but the EQ2 needs 9 Volts, so the EQ2 cannot be powered directly from
USB. Make sure that you have plugged in the included 9V DC power supply when connecting to the
EQ2's USB port.
When connecting the EQ2 to a recording interface or mixer, should I use a Lo-Z
(microphone) or Hi-Z (line / instrument) input?
The EQ2's output will be low impedance when the effect is active or in buffered bypass mode, but it
will be high impedance when using true bypass mode and a guitar with passive pickups. Therefore, it
is recommended that you use a high impedance (Hi-Z) input on your recording interface or mixer to
avoid signal loss.
