    I have soldered on top of pots with 25-watt iron, but you have to be careful not to damage the pot. The only time my 25 watt wasn't enough was when I was grounding a filter board to a chassis, the 25 didn't even come close to getting that job done.

    There's nothing that says you can't take all your grounds to a common eyelet screwed into shielding tape instead of soldering to the pot back; as matter of fact, I prefer doing my Strats and Teles this way. You could do something similar in a semi, but then the pot backs wouldn't be grounded as they would be on the shielding tape of a solid.

    you need good solder, that lead free crap is a disaster. Kester or Chandler.. Iron should be around 400 degrees. Lightly sand the back of the pot(scratched and clean) and tin your leads and tip of soldering iron. Hot and quick is better than not so hot and not so quick. also place a heat shrink on the the uninsulated, stranded lead wire that is going to be soldered to the pot.. this will keep heat energy from climbing through the lead too far. plus I cant say enough about star grounding... IMO

    ps. for a few yrs early on in my biz, I soldered some 2000 pedals w this Weller and at the time, ran lug 1 of the gain pot to the back of the pot w another fed over to the dc jack. so I have done waaaay too much pot... soldering :)


    ..but this one is best, and I lurve it.

    As Tavo said---use the right solder---60/40 is the stuff.

    Get you a nice set up with a digital power supply, you will love it. I struggled along with a cruddy little iron for far too long.

    A nice soldering station makes life easy. I guess now that you brought up this thread I should go finish my patch cables!
