Quick question that's not too much of a derail I hope... I've ordered a couple of pedal wiring kits from http://www.diyguitarpedals.com.au and just wanted to ask about soldering irons when working on tiny PCBs. What should I get? The one I have used on guitar wiring feels like it's too big. Should I get one of the really small gas ones? I don't mind spending a few bucks as I figure a good one is a decent investment... any advice on the best one to get?
