I checked most that you listed, and Fast Audio Peak Limiter seems to be the one to me that might help in tackling the problem of outstanding peaks in the signal of my guitar. The description mentions certain aspects from that it seems it might work.

But from elsewhere I was suggested to try these:
Really Cheap Compressor (by mictester)
Bearhug FET Compressor

Do you know anything about them? Can they do a better job than the Fast Audio limiter?

I took a photo of another test and you can see from it about how much cut would be needed to tackle the problem. Above the green line, that part should be cut:

I know mictester's circuit is well-respected, as is Jon Patton's, but I couldn't tell you whether the Really Cheap Compressor or Bearhug do a better job than the Fast Audio Limiter.

They're small simple circuits, though, so it wouldn't be too much trouble to try all three.

I am looking to build the Fast Audio Limiter. The schematic is below. Do the connections needs to go as indicated by me onn the image, or did I interpret something wrong? Guitar pedals that I disassembled had a metal spring as well that was soldered to the circuit board and was touching the metal box of the pedal. Do I need anything like that here, too, and if yes, where is that point in the schematic that should be connected to the metal spring?

 

[jimilee]

Yes and no. The gnd should be pads on the circuit board that connect to the sleeves and the dc jack neg.

Can you draw on the image what you mean exactly? Draw to whichever DC plug is needed for this.

What jimilee means is that the PCB should have ground-pads to connect to, which should be on the PCB itself without having them shown in a schematic, such as the one you've provided. If the PCB doesn't have a ground pad, then it's poorly conceived.


Note in the DIAGRAM Below: you can see the ground-pad to the right of the LED's pads; note as well there are additional ground pads for both jacks as well as ground pads on both the 3PDT daughter-board PCB to the MAIN-PCB. These jacks are NOT isolated, as in they're made of metal that contacts with the metal-alloy-enclosure — so the enclosure is grounded through the jacks (you could have one jack isolated, ie non-conductive plastic, so long as that jack's sleeve-connection is grounded to the board) — so, no need for a metal-spring from the PCB to the enclosure in this particular case.
