If you use the cheap soldering irons without temp. control (which are the only find I've ever used for pedal work), resign yourself to replacing the tips often. They run hot, and the high temps just chew up the tips in a hurry. I keep a healthy supply of tips on hand, because I rarely get more than a couple of builds out of a tip. I prefer the chisel-style tips, and they invariably develop a groove right in the middle of the chisel edge that gets deeper and deeper, until they're Y-shaped. The conical tips seem to last longer, but I don't find them as easy to use. Just personal preference--YMMV.

BTW, you should tin them immediately upon first use, because once they develop an oxide coating, getting them to tin up is very difficult. THIS STUFF helps in that regard. I usually treat the tip with this cleaner at the beginning and end of each session of use.

Waitin' patiently for those pix....
