well i managed to squeeze that dwell mod on, and theres room to tweak that tone too...

i'm getting confused with power ground, and signal ground though...hmmmm..i'll have a bit more of a tweak.

Here's quick and dirty revision of the Box of Hall schematic with the dwell components added in.

I just threw the extra parts in the existing circuit with paint.

I just designed a new fuzz circuit! It almost sounds a little different than the last fifty fuzz circuits I designed! ;)

180k/ 100n's?...is this for more/better feedback?

I used the values of the BYOC dwell.
Hold the phone on the Dwell mod for a bit......I was bouncing back and forth looking at the drawings. I printed them both and can give a better interpretation of what's going on. To quote a famous movie line....."I'll be back!"

Okay I got it. Let me revise the drawing.

I corrected the drawing in reply #61.

Parts of the original Box of Hall drawing are drawn kind of upside down from the BYOC drawing which I consider to be the "norm"

By the way, the 180K "feedback resistor" can be sized to your liking. It controls the max amount of feedback when the Dwell control is cranked. If the resistance isn't large enough the effect with self oscillate. You may want that effect on 10. I don't know. ???

You generally adjust that resistor to where it's just shy of self oscillation when the Dwell control is maxed.

pin 9 - 14 then, gotcha... :)


i'll have a tweak again...cheers larry. 8)

like this...


i'm still concerned about p -ground, and signal ground... ???

I'll take a look at what I did with the two grounds in my layout.

Okay,

Connect the digital ground to the analog ground without any interuption (connecting it to any other components) at the analog ground source. A good place would be the cap after the voltage regulator. Where C3 is grounded.

Hey Rob,

Looking at your layout, if you moved the 22nf cap down a bit and brought the incoming ground feed in on the grounded side of that cap, I think that would work fine. You'll have a direct path to analog and digital grounds from the source.

Yes sir!

Hey,

Can you do ground planes (pours) in DILC?

you can, using wide traces as bits n bobs to make it up....bit of a bodge, but yeah...sort of ;D


so move that 22nf down, and connect the ground to it.....sorry i'm confused,  so would i remove that jumper under the middle 100uf too?

I'll take your layout and do a real ulgy mock up in paint. Be right back.

Here it is...as ugly as can be! but you'll get the point.

http://www.aronnelson.com/gallery/main.php/v/diyuser/dwellverb1.jpg.html

You'll see there's a fairly direct path to the IC ground and to the Reverb brick grounds. I would star ground the incoming ground off board.

pins 4 and 2 on the brick are still the same ground though aren't they?.....(still confused) ;D..via that jumper under the 100uf.
