Guv'Nor Tonestack Vero - Check my work?

mr.adambeck · September 25, 2009, 11:19:14 PM

So, I made a vero for a Guv'Nor Tonestack from the following schematic I found on http://www.beavisaudio.com:

I've only ever made one layout, so I was hoping someone wouldn't mind double checking my work:

Please let me know if there are any corrections... I'm sure there probably will be!

Thanks!

Looks good to me. You can save some rows by squeezing some rez and cut traces....

mr.adambeck · September 25, 2009, 11:41:27 PM

Yeah, I know... I just wanted to get something that was correct first before I try to fine tune it...

mr.adambeck · September 26, 2009, 12:03:23 AM

Okay, this is a little more compact. If the other one would work, then so should this. If someone wouldn't mind double checking me again though, or has any suggestions to alter it, please let me know! I'm sure it could be even more compact, but I am tired and need to eat, so this is as far as I will get for tonight...

Basically I realized that all I use my Daddy-O for is as an EQ with a slight bit of gain. I literally barely have the gain up, it's more just to add a little more evilness to my tone for louder parts. It originally was going from an OCD into it, and it sounded nice and Marshall-y. However, I'm trying to phase out my OCD in favor of a Germanium Fuzz Face that I recently finished, and the fuzz sounds terrible through the Daddy-O. So I thought I'd build the EQ section and maybe combine it with a slightly dirty clean-boost or something and use it instead...
So... if anyone wants to suggest a good, but simple boost to combine with it, I'm looking for suggestions! Otherwise I'll probably just go with an LPB.

Oh, and here's the schematic again so you don't have to scroll back and forth!

The layout looks good to me. However, in parts list R10 should be 680, not 680K.

As for the boost, why not try Gus Smalleys NPN boost, it sounds great.

Great work

Regards

Carsten

Thanks! I updated the files, so it should be fixed now.

Hey, thanks for posting this. I just built it and it works great

You have written Trb-3 to Gnd underneath the layout and this appears to be a mistake but otherwise it matches the schematic you posted as far as I can tell.

I have a question about the treble control, it decreases the treble when I turn it clockwise, is this meant to happen because the other controls seem to increase when turned clockwise. I have double checked that I have the pot wired correctly and your vero layout matches the schematic.

I'm a noob at this so it is probably something simple that I am missing.

cheers

The treble should work the other way, i would check the two outside lugs of the treble pot and swap those wires over, then your treble should work correctly.

That is what I thought, I will swap the connections over. I guess that means the schematic is incorrect! I might be missing something (probably am) but the schematic matches the vero layout and my wiring matches the vero layout (triple checked) and the treble control works backwards

Hmmm... Interesting. I can't build this until I get an order of parts in (Pedal Parts Plus seems to be taking longer than usual lately.... aaaaaarargh!). It seems strange that just one pot would work the opposite way... Glad it works otherwise though!

Nice work! Just what I needed, going to build it later this week

Just curious. Any idea what frequencies this thing's set at?

I would love to know also, plus has anyone seen a frequency graph of how this acts? How flat can it get?

roseblood11 · September 29, 2009, 06:45:36 PM

Put the values into the Duncan Tonestack CAlculator...

I think it could be great to use this tonestack in a clone of the Catalinbread DLS...

mr.adambeck · September 29, 2009, 09:25:07 PM

Eventually I want to try it on a Big Muff... I've always loved the texture of the Big Muff's fuzz, but never liked it's tone control.

mr.adambeck · October 20, 2009, 06:31:02 PM

I still haven't built this, but did just realize that Treble 3 should not go to ground. It says that is should under the layout. That is wrong.

I dropped a Guvnor tone stack into a muff a while back and the result was less than stellar. I think youll need to tweak the values a bit to get them to work well with the muff circuit.

mr.adambeck · October 21, 2009, 01:02:59 AM

ok, fixed it. Here's the correct one.

I've decided to put off the Muff + Guv'Nor idea, but by any chance would you mind elaborating on what you didn't like about it? I have been thinking of building this in combo with a LPB as an EQ/boost to go after my germanium Fuzz Face and/or a Fulltone OCD.

I don't see how you could use Duncan's Tone Stack Calc for this, but I plugged the circuit
into ltspice to play with it. It seems to push a lot more bass through with a small mid
scoop. I can get the response pretty flat (between -8dB and -10dB across the frequency
range) if I set bass at 10%, mid at 100%, and treble at 80%.

I suspect that the part of the Guv'nor before the tone stack must attenuate bass
frequencies. . .
