BYOC 5 Knob Compressor

First Circuit Board build!

I won’t bore you too much with the blurb on the BYOC 5 Knob Compressor, as it can be found on their website here.

This was the first experience I have ever had of populating a circuit board, and I have to admit it was pretty straightforward, even though it might not look it:


In retrospect it’s not really an awful lot of components,  but I was extremely surprised with how straightforward and easy it was to complete.  I would heavily recommend BYOC kits to anyone who has a bit of soldering experience and wants to get into the foray of real effects pedal building.


The finish

How lucky I am that my companion is an artist.  Kelly kindly agreed to replicate some of her abstract work (found here) on the pedal enclosure, with the inspiration being the bottom middle and right pieces. Here’s the enclosure before she painted it:

And here it is afterwards;

Needless to say I was, and still am utterly stunned by the result of the painted enclosure.  I think it’s safe to say there is nothing else on the planet that looks like this pedal!

Here’s the guts inside, after being completed:

As a side note, having a separate PCB to solder straight onto the 3PDT made it a LOT easier. 

The 5 Knob compressor is a great pedal, to the extent where it’s one of my “always on” pedals, going into my Proco Rat.  I’d recommend the project, and the pedal, to anyone!

Finally, here’s some pics of the completed pedal (and yes, I know I have terrible handwriting!).

And as a final note, if anyone wishes to see more of Kelly’s work it can be found at
