looking forward to seeing how this goes!

my sincere condolences. r.i.p.

little feat!

these look amazing... i'd love to hear your techniques for "weathering" that top pedal.

thanks @gordo... i'll be ordering one of those neat little do-dads soon!

i've been working on a pig butt build that is rapidly eroding my confidence in my abilities and figured that i should probably invest in some testing tools to avoid issues in the future... as for the audio probe/test rig, i have a JMK pcb for the test rig that i need to build... i'm definitely going to look into the delyk one as well.

@Jebus, thanks. i figured as much. i have one of the JMK test rig pcbs that I haven't gotten around to populating yet... this build is making me feel like a total idiot haha. i swear i have some electronics experience and a few brain cells!

i guess i'll need to get a mouser order going to get the stuff for the test rig and a couple more builds... i'll definitely need a confidence boost after this one...

Yeah, I thought it was weird that the output jack wasn't grounded by wire!

So small update. Once properly grounded, I was getting a bypassed signal through the pedal. When I activated the effect, I got no signal whatsoever.

I then clipped the leads to board to remove the switch from the equation. I connected power (+9v and ground), and the input, output, and ground wires from the board. This left the "L" connection unconnected. When plugging in the power, the LED didn't light and I got no signal through the board. The LED should light, no?

Just a quick test before work. More testing later. Sigh...

That paper clip resistor cradle is brilliant!  Wished I'd thought of it.  I hate troubleshooting so I measure all my resistors as I populate the board.  It has reduced my box of fail ratio to near zilch.

I picked up a gizmo similar to the Tayda one and can't believe how accurate it is.  At least with resistors.  I scored mine on eBay for $12 after reading a post from Pink Jimi Photon.  I have no idea how they can pull that off, I'd think the zif socket alone would cost that much.  I mounted it to a bit of wood to give it a bit more heft so I don't break it.





I ended up doing the same with my Delyk test rig.  Keeps it stable on the bench and I don't have to worry about plugging something into the wrong terminal.



Guts go right from the rig to the box. Here's a gratuitous shot of the freshly minted AquaBoy with the Mod board.

any chance you have links to the resistor/ transistor tester and the test rig? thanks!

I have it wired up like the madbean build manual... the input jack is grounded, but the output jack isn't...

should i ground both?

one thing that i didn't do, that i should have, is test everything without the 3pdt switch. i am going to clip all the wires and test just the board that way when i can (either later tonight or tomorrow night). that way i can rule out the board having any issues...

if nothing else, this build is a great learning experience...

Here's a look at the board...

I ran into this as well, I think someone else posted something similar to this as well. Take anote alligator clips connected to ground and the other end touch it to one of the resistors in the tone bypass section. Should take care of theverything issue.  You only need to do it once, it's not like you have to make a permanent connection.  I'm not sure why it happens but it does...

hmmm... so connect ground to which resistor number? I tried connecting ground to resistors by the bypass switch, but it hasn't seemed to change anything...

hey all. I'm working on finishing a Pig Butt and have run into a brick wall.

1) the pedal is sans-box... i am in the process of rocking before boxing . I have gone through and verified the values of all components. I can post a picture of the board tomorrow morning, just to make sure that I've not done something stupid like put my electrolytics in backwards. I did graze a box cap with the iron and melted part of the corner. Could that be the issue?

2) when i plug in power and actuate the footswitch, the led turns on. i have measured the voltages of ic's and recorded the following:

4558: 1) 4.57V, 2) 4.59V, 3) 4.49V, 4) 1.2mV, 5) 4.52V, 6)4.57V, 7) 4.5V, 9.1V. While there a few values that are a tiny bit off, I feel like these are close enough (correct me if I'm wrong).

LM471: 1) 4.9mV, 2) 4.96V, 3) 4.77V, 4) 1.3mV, 5) 5mV, 6) 4.98V, 7) 9.11V. These seem a bit wonky...

3) when i plug anything into the pedal, whether it is "on" or "off" i get a horrendous buzzing sound.

I'm at a bit of a loss as to how to proceed, other than clipping all my leads to the board and retrying wiring things with a new switch. I have to say, my pride is a bit hurt. This is not my first electronics rodeo, and didn't think I'd be felled by a "Cowboy" level pedal...

Thoughts? Please don't hesitate to ask any additional questions that may clarify things. Thanks in advance for your help

I'd love to know more details about your laser etching process! I'd love you try it out .

Hi all, I am working on my second build (Pig Butt) while waiting for some additional parts to arrive for my first build (Multiplex Echo Machine). I was wondering, is there any advantage to socketing the diodes? I'm not sure if they are clipping diodes or not... I know the Pig Butt is an op amp fuzz, so I wasn't sure.

If you do recommend socketing, what other diodes would you recommend trying instead of the stock 1N914 and 1N5817.

It is a bit embarrassing, but I have had this 1776 board for almost 2 years... I just never made the initial investment to get all the components as I had to pinch some pennies for a little while.

I ordered enough parts to do three builds. The next two will be a Slow Loris and a Pig Butt. I'd rather have gone with the Mudbunny, but it wasn't in stock when I was ready to order boards. I guess I'll have to put that in the queue .

The other embarrassing thing is that I'm not primarily a guitarist...I am actually a drummer. I dabble in guitar and bass, but am in no way proficient. I do love electronics projects, and know that I'll enjoy playing through this pedal when it's done! At the very least, maybe it'll see some recording time when my band goes into the studio in the near future .
