What is the standard size dc input jack socket for music equipment i.e. mini amps and guitar effects gadgets?
I am wanting to use a 2.5mm or a 2.1mm dc input socket, I was just wondering if there was a 'standard' size connector. I'm sure I have heard there is one size commonly used in guitar effects pedals and equipment like that.
It doesn't really matter, because this is likely to be a one- off product, but if something breaks a few years down the line then I would like to be able to say i'd used the most common jack, so i can get a replacement.
