Here is a great project from effectslayouts that was recently released. Based on the old freedom amplifier's preamp section. Could use it to go direct to a daw or as a different flavor of overdrive. Josh Scott did a video on the amp and gives a great idea of the tone. Straight forward build with no issues. Artwork inspired by @jjjimi84.

Nice job man, I like it. How does it sound?
Pedal building is like the opposite of sex.  All the fun stuff happens before you get in the box.

Is anyone here old enough to remember "Freedom Rock"? Cause that's where my mind went right away.

Another tidy build by Thewintersoldier- can you tell us what's going on with the "BITE" control?  There's no explanation in the build doc, and the "GAIN" and "VOLUME" functions are already spoken for- I'm puzzled

I must not be old enough, but can I assume that it's the nationalist-propaganda-ridden precursor to "School House Rock?"

This is from the EHX website:
Bite-Alters the amplifier's gain level and frequency response. Turning this control clockwise increases the gain and treble content. This control is also very interactive with the VOLUME control; changing one affects the other.

In the 80's there was a commercial that played on television all the time for one of those LP compilation type records. It was two redneck type guys sitting at the back of a pickup truck, music in the background. One dude goes "Is that Freedom Rock? Well TURN IT UP!".

So, yeah, like the most USA thing ever.

Huh- thanks.
That's what I would've assumed if there weren't already knobs labeled "GAIN" and "TONE," I guess the "BITE" nibbles things in-between?
I put my lab-coat on and checked out the schematic but since they're not connected to clipping diodes, it's a bit out of my ballpark.  I did, however, notice that the EHX only had "VOLUME" "BITE" and "TONE" controls which makes a lot more sense, then Effects Layouts came and made it more spicy- I think I'm starting to understand.

Literally every one of my Dads' favorite tracks are on those 4 records, 3 cassettes or 2 CD's!

Maybe you're remembering real Americans and not the commercial?
