franfranky's review (This content has been automatically translated from French)" simple, effective and bidouillable"

Electro-Harmonix Doctor Q (Reissue)
U.S. pedal, an inlet, an outlet, a knob frequency selection (rather limited), a switch guitar / bass (totally unnecessary but would stay again).

Clearly this is a filter which triggers whawha typed according to the frequency and attack.


The switch guitar / bass is useless: the position smashes guitar volume, so I do the switch and shunt farted while the "down" position (the switch has allowed the passage of electronics troubleshooting a fender jaguar).

the knob to select the firing frequency of the filter, rather limited ... Fortunately there a trim pot in the pedal which adjusts the frequency of the filter more important: a stroke drill, here I am and have been tinkering with a second knob to adjust the frequency allowing the use of low (even 5-string) guitar pans and other ...


correct sound quality, simple but effective when it is properly adjusted.
I have not found it distorted the sound of the instrument.


I had replaced by an Enigma EHX Q ball for my bass, finally coming back to the doctor Q, simpler and less-brainer to put a key to my funky bass lines.
settings are minimal, making simplistic (easy to tinker ...), it is not expensive. So for occasional use no-brainer it's not bad.

Guillaume LANGEVIN's review (This content has been automatically translated from French)

Electro-Harmonix Doctor Q (Reissue)
A nice filter as EHX knows them, something that makes groiiiiiiinnng poooouuuuaaa ppoooouuaaaa wholesale. That's all analog, we are left with an IN, OUT, and a plug for the AC adapter (note taking is 3.5mm) and is all but enough.
Front, a switch ON / OFF, an LED, a wheel and a small button to a mode "bass". We will come back ...


Ultra simplistic configuration, there is not even a booklet included with the pedal is so childish.
Editing sounds very easy as there are only two parameters to configure.


Q The doctor is like the whole series of EHX Q (Mini Qtron, Qtron, Qtron +, etc. ...), it an ideal filter for the funk, which produces a sound approximating (and not the same, just to give an idea) a autowah. The filter responds to the attack on the strings, the sound is very "chewing gum" as the MNI Q-tron, for example.
BUT BUT BUT this pedal has two major flaws:
1) - A low on this pedal is useless, the filter should not affect the frequencies of the bass, in short it is nothing at all, no signal in "scratch" and a signal nearly identical to the original with bass mode
2) - Mode "scratching" down significantly the volume without knowing why. This is particularly annoying because the sound is not bad.


I've had about a month. I have owned before a Mini Q-tron, which I miss terribly elsewhere. The Q Doctor, even if it is cheaper, less well, finally I find. The filter sounds worse than the Mini Q-tron, and then this story is really baggy volume, it makes the pedal almost unusable.

Most of Doctor Q:
- Nice sound at high volume
- Mode "bass" is very good with a guitar ...
- Effect untiliser very simple and very strong.
- Value / Price

The - the Doctor Q:
- Only works with absolutely no bass.
- Its very down mode "Normal" (knob up).
