Stuff you wanted to know but were afraid to ask

I assumed if you short circuit a capacitor or a resistor it is essentially out of the circuit because electricity will take the path of least resistance and since the resistance of a bare wire is near 0 that's where current will flow. Then I was looking at the schematic for the Engl Fireball and noticed the depth switch at the beginning, see the snapshot below, full schematic at https://el34world.com/charts/Schematics/files/Engl/Engl_fireball.pdf
Shouldn't it make no difference if the cap is connected or not since it is shorted anyway?

It's allowing certain frequencies around the pot from the looks of it.
Since the gain pot induces resistance, the depth adds a parallel alternate path of less resistance , frequency dependant via cap values.
 
I don't see a depth switch on the panel of a fireball anyways.
Only on the 60 and 100, not the little 25.

These two don't seem to be using any protection.

Responsible pedal chaperones will keep a minimum distance between pedals' jacks with appropriate patch cables and will ensure there's a buffer somewhere in the chain.

Somebody lets un-buffered pedals couple like that depicted, then that player deserves the resulting inundation of 1590As...


Just sayin' ...

Practice safely.
 
I've been using smd jfets more recently and have been soldering them as one of the last steps while populating the board. I know some components are sensitive to heat (IC chips/transistors), but is it okay to solder the smd jfets as a first step, before there are components in the way of the soldering iron?

I have smd>to92 boards which I use sometimes if I'm jfet rolling, but have a decent stash of loose jfet smds. I have no issue soldering them (especially since I bought a fine needle-tip angled tweezers) and I'm also not a dufus burning the board. Just wondering if soldering the rest of the components after I solder the smd jfets first would cause an issue?
 
I solder the smd parts to the board first. Never had an issue (except for that one time where the FET was fake and then I lifted a trace trying to swap it out), but I never even considered that it may be putting a lot of heat on the lil guys.
