The annoying thing is I can't find where I saw this layout at first!
Everywhere I look people seem to use different value capacitors and resistors, so I guess it doesn't matter that much, but probably there within a certain range of value.
If someone could post a breadboard layout or a drawing, whatever just not a schematic, I would be soooo happy!
The main problem is that ¨they¨ use a 25? rheostat which is more or less impossible to get. This is what i want to somehow come around :p...
The 25 ohm rheostat is what's found in the Little Gem. Of course, you don't need an actual rheostat; you can use a pot. So whatever layout you're referring too, sounds as if someone just added that transistor as an output stage (or not, hard to tell the intent here, maybe it's supposed to be an input buffer, as in the Ruby, but then it wouldn't be connected directly to the speaker).
I don't use Fritzing, but if I were breadboarding this, I'd start by putting the +9V and GND leads from the battery into the power rails on the breadboard. I think that will simplify your layout.
The decoupling capacitor isn't hugely critical. The caps on the output will affect the tone, as they comprise a frequency dependent filter.
Looking at the LM386 pinout, it appears you don't have pin 5 (output) connected to anything. Your picture shows the indicator divot on the left, over by the "L", so that puts pin 5 above and right from the "6". And, as the pins on the transistor aren't labeled, it's hard to say whether those are correctly connected either. The pinout on that is GSD, but your fritzing drawing doesn't show which direction it's oriented.
I'm just guessing here, based on some small exposure to the LM386. Really would be good to see a schematic of the circuit you're trying to reproduce. 4 lines going to 'volume and gain control' aren't really helpful, because they don't show what's in that yellow box, and how those wires are connected to that.
