This maybe for the outdoor board too? But only needed for guitar.

Which soldering iron would be needed? What is sufficient. I mean they have $200 soldering stations on Amazon and there are $7 pens. What is best?

I understand through a little research that soldering wire to the harness and "tabs" of the switch requires less heat than soldering grounds to the back of pots. So a variable temp/wattage iron looks best. What wattage does both jobs? Is 60W overkill. Can I buy an iron that is "too hot" for what I need.

The difference in price in all the things I am looking at is about 10 bucks. You are spending 20 or 30 bucks, or you are stepping up to Weller soldering stations that can go for $60-200?

Thanks in advance.

You are overthinking this.

You are more likely to screw up from lack of soldering experience/technique than from heat. It is a fairly simple solder joint. You aren’t soldering mega expensive, super sensitive electronics that need ultimate heat control.

Just melt the tin and be on your way.

Also, you should practice a little before messing with something you need or care about.

Have you chimed in one of my guitar threads before? This is a “water is wet” point. Lol.

Thanks for the input afterward though. So a $29 kit with a 60w tip or adjustable to 60w is MORE than enough, but not hot enough to damage anything?

Yep. Plan on practicing.

I like the 60w Weller iron at Lowe's if I was going to recommend a first iron.

I don't care if you're using 60 watts or 6000, you can fry stuff if you stay in/on too long, particularly capacitors. Get the business done and get the heat out of there. I use alligator clips as heat sinks/isolators if I'm working with or around vintage capacitors.

Watch YouTube videos on tinning your iron tip and keep it tinned, clean, non-rusty. Very important for getting quality, clean looking results.

Remember too that interchangeable tips exist for a reason. I usually use a sharp pointed tip for guitar cavity work.

For soldering stubborn pot backs and especially tremolo claws ...

a.) clean leftover/trace manufacturing lubricants off the pot backs with rubbing alcohol and a rag before you begin work.

b.) take an ice pick or a nail and scratch tic-tac-toes or X-like shapes at the solder contact point, or abrade with some coarse sandpaper. AKA, give the surface itself better ability to grasp the solder.

When I solder a insulated wire to a terminal such as the lead from a pickup to a pot or switch, and the wire has PVC plastic insulation, after stripping the insulation off, and exposing the needed amount of bare wire I place a piece of heat shrink tubing with a diameter just slightly larger than the wire and maybe 1/4" to 3/8" long over the wire insulation up to where the exposed wire starts. This helps greatly to prevent the insulation from melting back as you solder and gives a nice finished appearance to the connection. I wish manufacturers would use Teflon insulated wire on everything, doesn't melt.
