Electro-Harmonix DOCTOR Q Quick Start Manual

DOCTOR Q
Congratulations! You have just purchased the DOCTOR Q, the
classic envelope funk box. Exactly the same as the original
DOCTOR Q, but in a more compact package.

-CONTROLS-

RANGE CONTROL— Controls the frequency range in which the filter
moves. The DOCTOR Q responds to your picking dynamics. Depending on
your guitar volume control, the DOCTOR Q's RANGE control and how hard
you pick, different wah-like effects will be produced. The range of the filter is
determined by the interaction of instrument volume and the RANGE control.
Both stronger attacks and higher (clockwise) control settings increase the
sweep range. Low volume and low RANGE settings will create little or no
sweep.
BASS SWITCH — When in the up position allows more low frequencies to
pass. Use to boost lower frequencies when the DOCTOR Q is set to create
little or no filter sweep.
FOOTSWITCH – Selects whether the DOCTOR Q is engaged or in True
Bypass. The corresponding LED will be lit when the pedal is engaged, and
dark when True Bypassed.
