Forgive me this might sound a bit dumb. I was wondering how do you figure out, what kind of electronic components to put in a circuit, to get a certain sound? For example if i want to build a fuzzbox, what kind of components do i need to get that fuzzy effect, i mean do certain capacitors or resistor ratings or whatever get you that fuzzy effect?

I'm a complete noob but what I assume you do (or start out doing) is copy professional fx layouts. They'll have specific capacitors and I guess later on you could experiment and see if different ones give you a better sound.

You mean you want a mod list to what you can do to a simple fuzz pedal?

Simple, I mean a fuzz face. While there is schematics for almost a lot of fuzz pedals. Fuzz face is the most simple one and easiest to mod.

Here is a picture with the popular mods to a fuzz face

also adding a tone pot is pretty cool.

tames the highs

I built my fuzz face with BC108 low Hfe vs the High hfe
The original ones used in the 70's were in 400 hfe area. Those were BC108 C mine are just BC108 at 100 hfe. It gives a smoother fuzz less gain and similar to germanium fuzz faces, I also used hendrix mod and changed the values on the pots.

At lower settings on the fuzz knob it sounds similar to an overdrive. Which i love!

I guess i would like to know more about what certain components do in a circuit. Suppose you want to build a pedal from scratch that is completely tailored to your taste (be it a fuzz pedal, compressor, wah-wah, whichever...) without any pre-existing schematics. You would have to know what kind of componets to put in, to get that desired sound you want. Know what i mean?

The values depend on the circuit.

Probably the most common ones are capacitors, because if you think about it, it makes sense.
Capacitors have less resistance the higher the frequency and the smaller the cap, which means a cap that works perfectly for a guitar will likely filter out a lot of a bass's sound.
Makes sense, yeah? So which caps?

Start by looking for caps directly in series with the input and outputs. Replace with higher values.
After that, you might want to look for basic high pass circuits. Pic related.
The formula for the frequency is 1/2pi*Resistance*Capacitance. You don't need to use it or anything. The point is that the bigger the cap and the bigger the resistor in this arrangement, the more lows get through.

Anyway, use your ears most of all. Sometimes you *want* some lows filtered out to keep clarity. Sometimes something that looks like a high pass filter act differently because it's not in the signal path the way you expect.

It's not so hard. Just look for input caps and highpass filters and adjust them until they sound better.

I hate it when I say dumb shit.
>a cap that works perfectly for a guitar will likely filter out a lot of the bass's sound
Implies you gotta change every cap in the signal path.
That would be retarded.

>1/2pi*Resistance*Capacitance
1/(2piRC).
Not (1/2pi)RC.
One over the whole thing.

Use standarad small signal transistors with normal H-fe (current amplification factor). In the range of about 50. And Ic (Collector current) about 100mA to 500mA
I would use NPN: BC547, PNP:BC557
Just because I have tons of these

Oh dude, since this is your first build, you should totally mod it down the line.

What you do is you get an IC socket, cut it so you have two pieces with three pins, and use that to swap out transistors easily without soldering.
That way you can take your time finding germaniums, or cool leaky Sis, or whatever else you find about Fuzz Face transistors cause there's a crapton.

I came up with that socket idea independently, but when I tried it the transistors wouldn't stay in very well.

So what would someone need for their first pedal, down to the very basics?

So far I've got:

>> No.31933

>>31912
You should be able to use a basic socket. It might help to kink the leads for the transistor to line up.
I guess it depends on why it doesn't stay in. Maybe they're really fat sockets?

Breadboards help.
A mistake on breadboard is a little bit less frustrating to fix. Plus they make experimenting easier.
