EH Doctor Q

Back to the Gear Room

So I just bought an Electro Harmonix Doctor Q envelope funk box. Instead of giving me a nice funk sound, it gives me nothing at all, just that weird hissing sound that wah pedals give off sometimes. I've heard you can adjust them internally? It was only like 50 bucks so i guess you get what you pay for. Or...could it be the setup I'm running with it? Green Bullet> Boss Equalizer>Doctor Q>Sonic Stomp. ????????? Any ideas?

Never tried that pedal. BUT there are a lot of guitar effects pedals that are NOT harp friendly. I have an Electro Harmonix Micro POG which IS harp friendly, so it's not the brand. It's a pedal by pedal determination. Some sound good with a signal from a harmonica coming through a mic and some don't. Btw, it can make a difference with some pedals if they are between the mic and the amp or if they are put into an effects loop (if your amp has an effects loop).

Also, sometimes a pedal that does not sound good will sound better if a compressor is put in front of it. A signal from a bullet mic is nothing like the signal many pedals are designed to process. If you use a compressor try it first in the chain between the mic and the amp. Btw, some harp players like the Maxxon envelope pedal, but I've never tried one myself.

You probably already have done what I'm about to suggest, but I'd try it without the Sonic Stomp, and if you can do so without feedback, without the equalizer. Also, make sure that it has a good power supply. Some pedals hiss if the voltage isn't quite right.

Lastly, if you have an electric guitar, or know someone who does, you could test it with that instrument and see if it works.

As John P noted, some guitar pedals just do nearly nothing with harmonica, and others have more of an effect on harp than they do with guitar.

Good Luck
