Solid State Guitar Amp Forum | DIY Guitar Amplifiers

Hi all

I am planning to combine a tonestack (phabbtone) and a noisy cricket. For that reason I am redrawing the noisy cricket schematic in its most basic form: without on/off switch and without LED. Could anyone please take a look at this schematic to see if I have it right?
I have replaced the pots with solder pads to be able to solder them off board.

I am still quite new to all of this so I would really appreciate it if someone would take a minute to see if this schematic is right...

Tnx a lot

Sorry but this schematic makes no sense. :(
Please "go by the book" until you have more experience.
Start practicing the tried and true before starting mods and such.
Like on everything else ;)

seriously.. that bad?
this is the original provided by beavis audio:

I seriously do not see that much difference... apart from the solder pads for the pots and the different type of chip since eagle did not have the original.. could you please tell me what I am doing wrong?

Cheers

the LM386 is not a dual op-amp. You used an LM358 which is a dual op amp... That's why your schematic is confusing. A triangle is generally used to indicate an amplifier or buffer (often an op amp but not always). The LM358 being a dual op-amp automatically drops two op-amp symbols into your schematic. You either need to use the correct LM386 schematic component in your schematic capture utility or create a custom one.

Agree and add: they are both DIP8 cases ... and nothing else matches.
They are *absolutely* different both functionally and inside.

thank you both... working on a corrected version!

ok... so it should look something like this:
