Title: Egghead Mods - any way to make it sound a little less thin?
Post by: greysun on March 27, 2014, 04:32:22 PM
I built a couple eggheads last year cause 1) I had stuff to etch them and 2) I had the parts and wanted a simple overdrive.

The problem is that it's not quite living up the way I'd like it to. The presence is tough to hone in, and the sound is a little thin compared to clean tone.

Is there any way to beef up the sound a bit? I've read somewhere that C1 and C5 to 1uf could make a difference.

I'm not really looking for more distortion. I did use a slow loris in overdrive mode through the LED clip and it sounds good, but that has the opposite effect - too much bass.

Anyone have any advice on how I might be able to beef the tone up a bit on these Eggheads?

Increase C3 from 47n to either 100n or 150n. This will fatten it up. Socket to find your favorite value there.

here's a thinker... let's look at this like a mud bunny with mids mod... in that instance, a resistor (I think r18?) is replaced by a 25k pot with a 4k7 resistor across pins 1 and 2 and the sound can be further tweaked.

For this egghead pedal, in addition to the changing c3, can one of the resistors be replaced with a pot that can be used in addition to presence for tone control?

Just thinking out loud and seeing how much control I can get with this pedal. I like what it does, it's just not meshing well with my setup currently.
