I know there are other forums that have addressed this but wanted to consult the sharp minds here before I proceed. I have a 3PDT switch acting up on an Electro Harmonix Soul Food pedal. It's about 6 years old, so I think I will go ahead replace the switch.
I have plenty of solder braid/wick, but no solder sucker. Worth the time and money to get a sucker for this? I like saving money but willing to do it right and grab a sucker pen if that's going to save me some heartache. Attached a photo. The switch is connected to a smaller PCB that ties into the larger circuit.
Thanks in advance!

The "proper" tool would be a de-soldering tool, heats up, melts solder, hit switch to suck.
I don't have one, not a big fan of the mechanical suckers + solder pencil, so I use fluxed wick.
do 1 post, then next, don't "stay on" the same post, work them all and let things cool. You're supposed to mask up n hole-up in the basement anyway so plenty of time

Thanks, Shooter.

I use the original Soldapullt DS017 with desoldering braid

Look a great tool, I did not know these desoldering tool. Very expensive !

I picked up one of these solder suckers a while back and it works pretty darn good. How long it will last I don't know but no signs of breaking down yet. I don't do as much desoldering as some other
people do though. It's just a good low cost tool.

Look close to my Soldapullt DS107 wich last many hundred desoldering.

I have never been able to figure out the proper technique for using solder wick/braid... there must be a way to make it work, but I have not found it.

never been able to figure out
buy a roll of 2.5mm "no-clean" wick, smash the plastic off your '80s boombox and wick off the solder, when you're done, you'll have the hang of it :icon_biggrin:
assuming what you want out is bad
cut it out, ic's, R's, caps, etc, that way you have less metal sucking precious heat from the task at hand.
the key to desoldering PCB is NOT try n get all the solder the 1st pass, move around, let previous joint cool. keep each "heat/wick cycle" to ~ 2seconds after flow, then you're done, let it cool, move on. Also, start ~ 2" from the end, when flow happens, pull the wick and wrap around the lead til you hit the end, cut off and repeat.
most of the time 1 pass will be enough to "crack" the remaining solder by using pliers to gently wiggle the lead, DON'T pull, that's how pads get ripped.
once the lead is out, lay the wick flat on the pad, apply heat and pull wick easy to "clean up" the left over solder

Here's a little smaller solder sucker, I use this one and a larger one like DL posted for different things.
