two seperate questions - transistors and LED

[gliptitude]

i am looking at two diagrams for adding an LED to a box with only a DPDT switch (and an additional resistor).  (diagrams found at generalguitargadgets.com)

one version says "Effect output is not bypassed" and the other says "Effect input is not bypassed". what does this mean and what is the difference, in terms of result?

also, on a completely different subject, what are transistor "sockets"? what does socketing mean and what does it apply to?

thank you.

Hi, -not sure about the first question - maybe if I saw the diagrams... anyway here is the article/diagram I first used to guide me when hooking up an LED/true bypass using a DPDT switch://www.geofex.com/Article_Folders/Millenium/millen.htm go to the last section - (Millennium 2) hope that helps.

Transistor sockets allow you to easily remove and plug in your transistors enabling you to try out different ones without soldering/desoldering. You can change the sound of your pedals by using different transistors.
Another good reason to use them is to avoid damaging the transistors with the soldering iron. If you overheat transistors you can ruin them. Germanium ones are especially sensitive. Diodes/LEDs and ICs are heat sensitive and you may want to socket them also if your soldering skills aren't that good yet.

The sockets are like little pins with a hole in the top that the component's lead plugs into. Check out some component retailer websites and you'll see what is available.
