Still being virgin to the mod scene, yet being the semi-insightful bastard I am... It would make a little sense to me, to install a socket if one were to replace an op amp. You're already there. Therefore alleviating the future need to de-solder/re-solder future replacements or experimentations. Being blind to the fact, are there that many possible variations of possible component replacements & do "most pedals" have enough room inside to house a socket for said procedure??? Other than "one more" contact point, do you see ANY down side to this thought?
Many thanks in advance to those who fill the empty void I dub as my cranium,

there are single pin sockets available but i find that the majority of the time that i do mods, i'm doing a mod to specs that have already been developed and so the need for multiple swapping is reduced.
for op amps, i generally use a socket always as it reduces the chance of overheating on the install.
i have cooked the pads off of a PCB before with too many component swaps (often when the factory solder was pretty bad).

I always use sockets (preferably the turned pin ones as suggested, they are better) whether I'm building from scratch or replacing existing parts. I'd rather not risk frying any ICs or (and it does happen) accidentally put them in the wrong way round...
I've heard people say there's a greater risk of corrosion of the contacts using sockets, or of ICs loosening and disconnecting, but I suppose that depends what you do to your gear  Never had any problems myself. |

Another vote for sockets.
Since they come in different styles, try them all until you find one that works for you...
...Then you can drive yourself mad swapping chips.
It's also a great insurance policy if you get addicted to chip stacking. If you smoke something while stacking, just throw 'em in the trash and start over. It's also a great way to become a master at flowing liquid tin! |

Machined IC Sockets are the way to go
Use them all the time, never had one fail.
Not the same story for the cheap single wipe types.
I have some horror stories about those.
They cost a few cents more, but last for ages.

| What about the dual wipe types, are they any good? I've used those in a BYOC slow gear project. I like how they grip the pins. |

That type are "OK". The machine ones are better...
I have over the years found chips that have occasionally fallen out of the wipe type, but never from the machine type. What happens is that every time the equipment goes through an on/off cycle the chip thermally expands then contracts and that can cause a it to "creep" out of the socket a fraction. Over a few years, it can creep right out of the socket.

Amazing. Chips often look like little electronic spiders to me and that does sort of add to the comparison. Will make sure I use the machine type for my DD 2 repair! |

You'll have to hook me up with your supplier. It's been many years since I last ingested any hallucinogens. This post makes me think I need to experiment some more.
