Yea this is the only place I can find with those smaller boards.

Now that I've spent a couple of months studying electronics basics, I want to learn more specifically pedal-related.
I've read almost all the pages of this threads, bookmarked a lot of useful stuff, and already started to mess around a bit with the breadboard - not enough, but I'm waiting for some components that should be here next month, so meanwhile I spend my time reading stuff for future knowledge.
What I'm asking right now is if somebody has some useful links to understand how components behave in certain circuits and what is their function in that specific configuration.
I've found some interesting stuff on diystompboxes and Electrosmash, plus some articles here and there, but I'm hungry for more.

:hug:

Go look at Steve's breadboard write ups on small bear. Buy a set of Ge trannies from him and do the deal.. you'll learn a ton about biasing and shit. :joy:

Thanks for the tip! Just had a fast look on the fuzz face article and it's really interesting. No surprise I didn't found those during my researches: they're not exactly easy to find unless you open smallbear shop page.
Thanks!

yes. start here

https://www.electronics-tutorials.ws/

read in this order
-resistors
-attenuators (optional)
-capacitors
-transistors
-amplifiers
-filters <--- first read page 2 https://www.electronics-tutorials.ws/fi ... ter_2.html
page 2 of filters is all you really need for guitar pedals. you can stop there or you can go back and read everything in filters. RC low pass filter is used in a guitar pedal power supply and it is used again in the audio circuits.

more advanced learning
-operational amplifiers
-diodes
-filters
-dc circuits
-ac circuits

also read this http://www.muzique.com/lab/swtc.htm

this will show you how to wire a tone control and how to wire a volume control.

http://www.muzique.com/lab/tips.htm

"Prevent Dull Volume Controls" is a tutorial about something that has another name. I call it a "treble bleed cap". there are ways to calculate the value of the volume pot and the recommended value of the treble bleed cap but that will take some time to learn. if the volume pot is 500K, it is very likely that you will need to add a treble bleed cap or sometimes a treble bleed cap in series with a resistor. common values would be something like (470pF + 22K Ohms) in series bleeding in parallel to a 500K pot pin 3 pin 2.

thanks guys! i somehow missed this when you posted it, super useful reading!

Some info on current mirrors. I have often seen these used in voltage controlled filters and oscillators.
