I think most schematics we work off don't include the switching and indicator led. The off board stuff almost never changes. Some of the companies who sell boards include a pad to connect the on/off LED hence it being included in the power section of the schematic you posted. Ultimately doing it that way saves a bit of trouble when things get wired up and boxed.

Brian is the king of the builder friendly layout.

Thanks matmosphere, I'll keep that in mind.

He is indeed the king.

The little pin marks represent pads on the PCB. The L pin in this schematic is used to connect the LED to ground via the foot switch to turn the LED on.

Edit:  I just noticed, there is no LED in the schematic    If you look at another schematics, there is usually an LED after the 4k7 resistor connected to the L pad.

Thanks for replying.
I see, so the "pin" marks are basically just an indication that you'll need a pad here to solder the input/output jack for example? The LED was my first thought but presumed there would be an LED symbol if so. Then again, I guess it's quite cosmetic in comparison to the other components. I may post a picture of the finished PCB design on here once I've plucked up the courage to get going!

Cheers again for your help.

Hi all,

I'm very pleased to have joined the community and I'm looking forward to learning a lot and hopefully helping others where I can down the line too. I've followed a few folks' journeys from the sidelines as they've worked on projects and have decided to take the plunge and start on one of the DIY projects myself.

I should say that I'm not a complete novice when it comes to understanding schematics; I spent most of a decade working as an electronic security engineer and I'm currently part way through an electrical/electronic engineering degree which has - as you may expect - involved some tinkering and PCB construction using Eagle and KiCad (the latter of which I'm hoping to use to design the PCB and have manufacturered at a boardhouse).

I'm having a go at the "BFC"/Keeley compressor clone and just wanted to clarify a few things before I start soldering and collecting the relevant parts which may be (I'm hoping) very simple.
The thing that is throwing me is the "L" label/flag in the power circuit section at the top of the schematic drawing. Is this a general notation and if so what might have I seen it as before? I understand the global labels for VB and VC and how they connect to other parts of the main circuit to provide a reference or supply voltage (e.g. 9V to the LM3080 IC etc.), but couldn't find another "L" within the schematic to do the same.

I was also hoping to clarify the round "pin" marks on the schematic and what they mean or if they're just referring to the footswitch connections or something?

I may just be being dim or perhaps it's just lack of confidence for the first build but I'd really appreciate any help.

Looking forward to hearing from you good folks.
