    Need help with a few parts

    If you have a delay I’d email them. I heard nothing for about 2 weeks and emailed. They were holding up the order for a single component that was out of stock. They ended up shipping it minus that piece. But it’s annoying. I used to always go to Mammoth first but after that experience (twice) I...

    Input jack

    If you look at the metal tongue part that the tip would hit when inserted into the jack, whichever one of the two upper tabs is connected to that tongue is the tip connection. The other one is the ground

    Chaos Machine 1u cap

    On the Chaos Machine, C10 is a 1u cap. I bought a electrolytic cap like I normally would for 1u. However the silkscreen is a square box, so clearly it’s not electrolytic. 1) can I use electrolytic? 2) does orientation matter? I think the answers are yes and yes, but not sure which way of the...

    What "bench" reference information would be useful to you?

    I have a printout taped to my pegboard of all the diameter sizes for all the holes to punch on the enclosure.

    Chalameau/Clari(not) LDR range?

    Thanks everyone for the advice. Can’t wait to make this one!

    Chalameau/Clari(not) LDR range?

    Has anyone who’s built the Chalameau clone of the Clari(not) know what the range of LDR is? Thanks in advance, James

    Double Pedal

    I just finished (almost) a monster box that uses a 1776 Multiplex Delay and a generic no name Chinese made tremolo. I use the pedalPCB order switcher and it’s super simple to wire up. There’s also a mod section for the Multiplex that I can’t get power to work yet. It also has a 4th footswitch...

    Op amp question

    Sometimes it will also specify whether the component is thru hole or surface mount (SMD) as well. Or just different versions of the same chip. I’ve seen all sorts of TL072 prefixes and suffixes. All the same IC chip.

    Muffin Factory V2

    I used a basic Germanium diode 1N34A. Any germanium diode should work.

    Hello, my name is bifurcation and I don't know how to use a multimeter

    Also an audio probe is super helpful for testing the signal path for trouble shooting pedal problems. There are plenty of guides by googling “audio probe”. Here’s one I used to make my probe. Really really simple, but super useful tool. https://www.diystompboxes.com/pedals/debug.html

    Phase II Problems

    I learned to use a audio probe on a really really basic fuzz with about 7 components. You can start touching the probe to the input and output jacks to get a feel of how it works. Just start at the Input jack on the schematic and start following from component to component. On a simple fuzz...

    Octagon with Expression Input

    It does get weird sometimes transitioning between one pot and the other. Not exactly portamento style slides, but rougher.

    Octagon with Expression Input

    Always have to keep missing the pedals! Another fun addition is a 2knob job PCB. It adds a second pot for 2 different settings that can be switched between with a 3pdt. Great for those infinite feedback swells or a major gain boost.

    Octagon with Expression Input

    Here’s bsonici’s original post on it. http://www.madbeanpedals.com/forum/index.php?PHPSESSID=23a5d4da5907bf871f0b7de0ded09492&topic=27601.msg267298#msg267298 I’ve also been looking for a couple weeks on line at adding EXP jack in general. Here’s some other links on the topic...

    What are your favorite PedalPCB pedals?

    All the FV-1 platform pedals are fun. I’ve build the USB version and the older D3lay/Kaleidoscope/Radium Springs EEPROM’s on the non-USB version lots of versatility between the chips you can swap out easily or code yourself on the USB version. Muffin Factory is so cool to build and sounds like...

    Duo-Phase

    Looks great! That’s wired up as 2 separate phasers correct? Also, which range LDR’s did you use? It didn’t specify on the list.

    Muffin Factory V2

    I used the Sanyo 2SD30’s. Hfe was 55 & 60 or something around there.

    Muffin Factory V2

    Yeah almost the same. 2 resistors slightly different values and a Ge diode for one of the 1N914’s. But nothing major. The added 4th and 5th toggle switch additions are very nice mods. I’d love to hear the v1 vs v2 side by side.

    Muffin Factory V2

    Good news everybody! I got the new Muffin Factory v2 to fire up and work today! When I first fired it up, I had a wet sound but no gain/fuzz whatsoever and started to panic...then I looked at all the little DIP switches and turned on the gain and clipping for the 1) input DIP 2) clipping stage...
