I've got a band practice immediately after work today, but need to grab a lead and some other bits beforehand. The prac is in London bridge, and I work in Hackney, is there anywhere is Hackney or inbetween that I can go to, that isn't hugely out of my way? All the music shops I know of are either right in the centre or really far out.

I've tried Google, Google is not my friend.
