parts to have on hand

[supremeseam]

I have a rudimentary understanding of circuits and I decided to start building guitar pedals. So far I've got a working LPB-1 clone on a breadboard (with an added gain adjustment) and I'm going to attempt to etch the PCB for it next week. I think my next project is going to be a distortion or fuzz pedal. Looking through the schematics they all seem to use different op amps and transistors, what would be a good assortment of these parts to have on hand and where do you guys get your parts from? Thanks for helping out a noob :-)

This thread had a really cool analysis of parts and how often you need them: https://www.madbeanpedals.com/forum/index.php?topic=30748.0

You really can't go wrong with buying a heap of TL072, they will do the job for most op amps.

As for where to buy, depends on where you are in the world, and whether a pandemic has closed things lately?  If you're in the USA, small bear and LMS linked in the header of this forum are good I believe.  Tayda electronics is good for cheap stuff I find.  DIYGP linked above is great for me in Australia.

That part analysis is a great resource. There is also some good stuff on this over on the Beavis audio page;

Good stuff.


Have a great time, and be careful etching.

Thank you. That was all really helpful.

I'm only etching boards so I can learn. I have to know what things are doing and why and the only way I'm going to learn that is by putting things together and breaking them :-). I already ordered a board from here and once that makes it to me safely I plan on buying a few more.
