Today's Sesame Street is sponsored by stupidly big enclosures
Project requested by my buddy Troy. It's not an vintage pedal, that's why not quite match my website profile, so let's say you guys have it exclusively
Not vintage, but with vintage vibe - it kinda based on 200W Marshall (Major?) amps, nicknamed "The Pig". How? Why? Click here to know more
My project is based on SonicIV's schematic, and my project i NOT verified
The trimmer on Q3 is changed to fixed resistor on my layout. Just take a 100k pot with wires on lug 2 and 3, clip or probe lug 2 to ground, lug 3 to Q3 gate, adjust to taste, remove the pot, measure it with DMM and pick the closes value and put in place as shown on my layout. It's actually more easier than dancing with a trimmer trying to fit that fuck on tags, nightmare, I'm telling you -I've been there, done that

No, not me, not now. I'm quite bored with FX units recently, I'm sorry broagoldoor wrote:Anyone care to do a vero for this? Bee dot? Sinner?

I'm inches away from doing a turret board layout and build for a Marshall Pig...

The Pig or Marshall Major? AFAIK they arn't the same

Pig! Major was just a plexi with a big back end but im gonna be building the three knob Pig version. I wont be doing the 200W back end on it, though. I think i might do it with 2xKT66 instead of 4xKT88.

Hi all,
I had a request for a vero of the Menatone Pig. Here it is;
Based on the work from turretboard.org
Let me know if/when someone verifies this sucker.
Cheers,
Dino

It works and sounds awesome.

Bumping for some questions and new info.
I had access to a Pig built this year and had a question. Turret Board's schematic shows a 22nf going from Q4's source to Lug 3 of the Gain control. In the version I have, the 22nf seems to go from the drain to Lug 3 of the Volume control while there's an added 22uf to ground from Q4's source (in parallel with R19). I may very well be wrong, so please correct me if I am. Also the following changes were noted...
C12- 500p
C13 - Omitted
R2 - 33k
R5 - 27k
R15 - 33k
R18 - 33k
R21 - 33k
R25 - 33k
R27 - 10k
100k trimmer replaced with a 22k resistor.
I like this pedal a lot. Personally I would drop the value of the Gain pot from 1M to 500k and spread the range. The Gain seems to reach max around noon and there are some great lesser gain shades to be had before noon that are easy to pass by. Hope this info helps.

The television will not be revolutionized.
Built this one from the layout in the original post and it sounds good. Mine barely has enough gain at max on the knob. How would I go about increasing the gain range?
All of my Q's are about 330 hfe
Thanks

Sounds like something's not right, this pedal has a ton o' gain on tap. Also, I mentioned in my previous post that the gain doesn't seem to increase in saturation much past noon but after spending more time with the pedal I realized that it does start to compress. Not a lot but it's noticeable.engineelite wrote:Built this one from the layout in the original post and it sounds good. Mine barely has enough gain at max on the knob.

Wait what? Are you using FETs or BJTs?engineelite wrote:Built this one from the layout in the original post and it sounds good. Mine barely has enough gain at max on the knob. How would I go about increasing the gain range?

I'm using all J201's and they are all about 330hfe, which seems like it might be on the low side but that's all I got from tayda. Maybe I should order them from another supplier.
..and I've now built 2 of these and they both sound and react the exact same way. It sounds good and all knobs work correctly but it just needs a little more gain on tap.

You don't measure Hfe (common emitter current gain) on JFETs, it's a parameter specific to BJTs. FWIW, all of the FETs I've ordered from Tayda have been fakes and don't work correctly in any circuit that requires them.engineelite wrote:I'm using all J201's and they are all about 330hfe, which seems like it might be on the low side but that's all I got from tayda.

Good to know. I dunno what the 330 is that I measured then. The tayda j201's worked perfectly (matched at 200) in my wampler plexi-drive but I'll order some from small bear since I know their stuff is legit. I'll report back when I get them installed. Thanks.
