A fantastic list of links that I'm sure I'll come back to many times... but.... is there any electronics supplier in SA that stocks the kinds of stuff that guitar builders need... eg a 3-way toggle switch for selecting pickups? a log pot with push/pull switch, etc.? or do I have to get it shipped from the US?
Not an electronics store, no. I usually Import whatever I need, but Marshall Cape import the DiMarzo range which has most of what you'll ever need. Speak to Gareth.
