Running a jumper from lug 1 to ground solved the problem.
But now it sounds way too bright. Time to throw the 500k back in.

Thanks for the heads up Brian.

That's odd. Lug 1 appears to be connected to the ground plane on the pcb. Perhaps I burnt up the connection when soldering the pot in? I dunno, I don't usually apply too much heat when soldering.

Aha! No continuity between lug 1 and ground!

Will do. Heading back down to the solder dungeon shortly.

Howdy gang,

I just recently built up a GE Fuzz Face using the Mangler 2011 pcb. It sounds great, but it is LOUD. The volume knob doesn't seem to dump out entirely to ground, as at fully CCW, it is louder than unity. It just gets much louder from there. I pulled the 500k volume pot and replaced it with a 100k, and while I like the brighter tone better, much like the 500k, the pot seems to do very little—it just goes from loud to a bit louder at the last 20% of the pot's rotation. My voltages are right where they should be, and all of my component values seem to be correct.
Has anyone else expereinced this with the Mangler 2011 board?
I've built many a Fuzz Face in the past, both GE and SI without problems (the vol goes silent at full CCW) but this one has got me stumped.

Transistors are old TI 2G308 at 60 and 120 hfe, very minimal leakage.

A lot of folks don't get the Action Park thing unless you grew up in the Northeast in the 80's.
Action Park was the most dangerous (and fun) amusement park period. The place was staffed by a crew of stoned and drunk kids and injuries were commonplace. People died there pretty much every summer.

We never went, as my mother was rightly cautious after a cousin came back from there with multiple lacerations and a broken collarbone. Yes... it was the Alpine Slide!

At Action Park is the name of Shellac's first LP.

Hey... girls talk. Lols

It sold almost instantly after re-listing it. Chuck can't stop me!

I've reposted the pedal on the evilbay. Ol' Chuck be damned.

Does it look as if I'm still infringing on his trademark?

I just noticed his listing states you can buy the pedal cheaper at theremaniacs.com. And that there is a direct violation of ebay rules. Report initiated.

So, I built me a couple of Harmonic Percolator clones on the MB Pepper Spray pcb. As I often do, I listed one on Evilbay to make a bit of scratch to fund more transistors, enclosures, beers, etc...

I wake up this morning to find my listing has been removed for "copyright violation" and was being called a "counterfeit item". The complaint was lodged by Chuck Collins, the guy who builds Interfax Harmonic Percolator clones.

Now... this pedal looks nothing like the Interfax unit (bright pink 1590B) nor did the listing claim it was an Interfax unit. As a matter of fact, the word "clone" was used throughout the listing. I have no recourse through ebay, and Chuck's complaint used a dead hotmail address.

I am I not correct in my understanding that the only thing that can be copyrighted is the PCB art?

I dunno, there are plenty of HP clones for sale on ebay. I don't know why he'd go after my single pedal.

I gave up on Mammoth years ago. They just could never get an order right.

Thought I'd give them another try recently, as it's hard to find large value rev log right angle pcb pots anywhere else. And their price is right.

Then I receive my order. Over half of my pots were missing washers and nuts. Sigh...

To their credit, they sent me the parts no charge.

But that was enough for me. Between Mouser, Smallbear and BLMS, I'm pretty well covered. No need to mess with Mammoth again.

Are the "mojo" pcb layouts a thing of the past? I just recently built up a TB MKIII on one of the old boards with the spacing for axial caps, and it sure did look pretty.

My experiences have been best with red leds. Yellow have been okay, and blue (higher forward voltage) barely clipped at all. There's a great thread  at diystompboxes from 2010 which was super helpful when I had the same questions.  www.diystompboxes.com/smfforum/index.php?topic=85219.0

But feel free to socket and experiment!

I had the same issue with my Deathklaw build. So glad I found this thread!

Running a 200hz sine wave into it with the blend set to fully clean, unity gain was definitely at 22k.
Playing it with a few guitars and pickup types confirmed this--although the hottest pickups on any of my guitars are Seth Lover HB's. I think they are 7-8k. YMMV

Wow! Just ordered 10 pieces. Came out to about $1.30 a piece USD.
Add in in international shipping, and it was about $18.
I've never ordered from Paul before, but I trust his stuff is legit.
Thanks for the heads up!!!
