Hey guys I need some help. I'm building a fuzz face and so I'm ordering parts. I don't want to be stuck to only using a battery, so would this DC socket work? http://www.maplin.co.uk/single-hole-fixing-2.5mm-dcsocket--1416

If not could you point me in the direction of a dc socket that will work with a fuzz face circuit? Needs to be in the UK, and as cheap as possible (but nothing shoddy). I faintly remember the fuzz face being awkwardly centre negative or something. Help?

Maybe the price tag is clouding your judgment ?
yeah probably. Or the circuits.

2.5mm is too big, most (99%) guitar pedals use 2.1mm. Can you post the schematic that you are working from? Centre-pin negative (ground) is the norm for pedals, and would be used if you were using NPN transistors, i.e. silicon BC108/109. In that case you would need this, in order that the outer shield, which is at a positive voltage, does not ground out on the case: http://doctortweek.co.uk/shop/article_92/Socket---DC-Power-Adapter-Socket-2.1mm-%28plastic%29.html?pse=apq.

However, if you are using PNP transistors such as in a germanium-based circuit, then you can use one of these instead, as the centre-pin will be positive, and thus it is acceptable for the shield to come into electrical contact with the case: http://www.maplin.co.uk/2.1mm-single-hole-fixing-dcsocket-1407
