Electro-Harmonix EHX Doctor Q Envelope Follower Reissue 2000's Guitar Filter Effect Pedal & Power Supply Used

Used with wear associated with use. Minor cosmetic scratches/scuffs from handling and play. Noteworthy blemishes or issues will be described and pictured. Works as it should.

We strongly recommend using the proper power supply for any pedal. Daisy chain power supplies may not supply enough power when using multiple pedals or introduce noise into the chain. Consult the pedal manual when available for manufacturer recommended power specifications.

Has very few scratches, and small traces of rust on the back side near jacks. Please see pictures for details.

Includes original power supply, wooden storage box, and paperwork.

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.
Input/Output jacks
9 volt power supply included, battery optional
