| | | | CALLING DOCTOR Q...a call for advice from the obsessed and bored
Sign in to disble this ad
Ok, I've posted quite a bit recently about my pedalboard setup, but now I have a new addition to the family, and I want some suggestions.
I was at guitar center to see what they had on sale this weekend, and I spotted a used EHX Doctor Q envelope follower for $20. I tried it out extensively on a few rigs, and I liked it. I have to wait for the police hold to end before I pick it up, so I have a week to sit and wonder wher it should go in my line-up, which is currently:
compressor>OD>spring reverb>chorus>octave divider(adjustable 2 down and 1 up)
Consider them all to be moveable, aside from the octaver, which is built into the amp. Where would you stick an envelope follower into this mess, and what kind of sounds can I expect? |

I've been running my OD after the compressor just to make it punchier, but that even robs the OD of some of its dynamics. I'll probably switch it.
Does anyone know how the good Doctor would interact with a chorus or reverb pedal? |

| | Pat's the best! | | Join Date: Dec 2000 Location: Northern Virginia, USA | | | Doctor Q! By strange coincidence I just picked one of these up myself. You definitely need to use it before the compressor!
Do some searches here you'll find that most comments about the Doctor Q are negative, though there are some positive ones as well. There is a little trim pot on the inside of the pedal which you should play with immediately if not sooner. Futzing with the little trim pot really brought my Doctor Q to life. I've only had it for a few days but I think I like it. It's subtle enough to give me a little funky wah effect without being too much (too much effect and too much money!).
Can't help you with how it interacts with a chorus or reverb. I'd be interested in what you think in regards to your OD since that's the only other pedal I'm using right now. |

Does anyone know what that pot actually controls??? I see it mentioned everywhere in online reviews, but nobody says what it does. |

I picked it up used. I'm pretty sure one of the previous owners tampered with it. The octaver (they call it Ultrabass) is one knob, and normally as you turn it clockwise it'll go from one octave down to two down, and increase how much effect is mixed with the dry signal. When I mess with the contouring function, I can eventually get it to go an octave up. The manual I found for the head sort of hints that you can do this, all it says is if you adjust the contour and octaver concurrently you'll get some "wild sounds!" or something stupid like that. The only complaint I have is that the octaver has some tracking issues, but compression fixes that for the most part. |

Before you play with it mark the original position with something; you could well find the factory-set position is as 'good' as it gets.

'Range' is quite clearly the pot right on the outside of the case, where you would expect knobs to be. I need to know what the trim pot inside the case does. Unless it also affects the range, in which case I look like a jerk. |

Anyway, both will interact to determine how the filter responds to your playing.

| | | | I'll bet its backwards, cuz the outside pot definitely controls the range. Sensitivity would make much sense. I've been afraid to touch it...will definitely mark my starting spot. |

| | Pat's the best! | | Join Date: Dec 2000 Location: Northern Virginia, USA | | | Sensitivity sounds right. DO NOT FEAR the trim pot. I'd like to set mine up with that as an externally accessible item. On my Doctor Q, the effect did -almost nothing- until I futzed with the trim pot. |

| | | Just got an email reply from EHX on what the internal control does....
"The trimpot is a factory adjustment used to calibrate the center frequency of the sweep. This is NOT intended to be an end user adjustment."
So EHX says I shouldn't touch it. What the HELLo is going on with this pot? I smell a conspiracy...  |

| Sounds like if the effect is set up for guitar that it may need to be adjusted to have the desired affect on bass frequencies for a bass guitar.........
Have you tried the effect yet? Got what you like out of it? I'll try to post a comparison later tonight. | | Thread Tools | Search this Thread | | | |
