Hey all,
total newbie here so be gentle.
I’ve build one pedal at a workshop so far and decided to get the Julius kit.
I’m having trouble identifying the components, has anyone got a clear photo of a populated board so I can sort out my parts?Thanks in advance.

hi, fellow novice here. welcome to your new obsession 🙂 i had no experience with electronics a few years ago. i would suggest finding a multimeter. its relatively easy to learn to read and will identify resistors and non-polarized caps without doubt. this is a must for me as my eyesight isn’t the best. diodes are few enough to id visually, or with careful deduction. with a few exceptions, the remaining parts will usually be clearly marked. get some workbench magnification if you have not already.
when dealing with a specific bill of materials, you might run into different descriptions of the same part. i.e. 100 nF (nanofarad) = 0.1 uF (microfarad). i found this utility to be extremely helpful to decipher farad units – http://www.unit-conversion.info/capacitance.html
i also found this build report, which doesn’t quite get you there. https://www.buildyourownguitar.com.au/forum/showthread.php?t=10364
other than that, dive in, have fun and you might even find your mistakes are happy accidents.
Thank you
If you are building the GuitarPCB “Julius” there is a link for the directions that contains the BOM (bill of materials) in the “Description” of the board here (https://guitarpcb.com/product/julius-a-historic-tribute-to-the-classic-orange-boost-compression-circuit/)

Thanks Steve
Doing well so far, not, had every labelled ready to go, started to populate the board with a few distractions in the middle, half way through I was missing bits, turns out I used the wrong resistors in a couple of spots. I wrecked the board trying to fix it so I’ve just ordered a new board and replacement parts…
I’m going to have to shut the door and turn off the phone the next time.
Some food for thought…. If you are going to build more than a few pedals might I suggest you purchase a couple of Items that will make de-soldering components much easier.
#1. A good solder pump (sucker) https://www.amazon.com/Solder-Sucker-Desoldering-Removal-Soldering/dp/B08FDY2SGS/ref=sr_1_1_sspa?crid=1Q152DUPPUAUN&keywords=solder+sucker&qid=1662135846&sprefix=solder+sucker%2Caps%2C139&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFPTFZJQjZFM0hDOUomZW5jcnlwdGVkSWQ9QTAyNDY4MTczNUJSQjFOM1hNRlUxJmVuY3J5cHRlZEFkSWQ9QTAwOTgxODEySFk5M09QWE5JM0w4JndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==
#2. A good brand of solder wick. Helps remove anything the solder sucker misses, https://www.amazon.com/gp/product/B005T8TNCY/ref=ppx_yo_dt_b_asin_image_o08_s00?ie=UTF8&psc=1
With those in your arsenal, along with some patients, your chances of destroying a PCB will be GREATLY reduced.
I do have a pump but I was unable to get it close enough to work, the wick I have on hand must be so old that it failed to do it’s job, before any of these could work the board looked like a cheese toastie…
