I bought a plectrum

God it was embarrasing. The wife kindly got me a guitar for my birthday so I thought I'd better get the bits n'bobs to go with. Trouble is it's just so intimidating - strolling into a guitar shop in London's Trendy West End and saying "I need a plectrum. Or is it a pick. Erm..." The guy said "help yourself", I said "what would you recommend" him: "they're all the same, just different colours" me "ok, two grey ones please, bye". None too rock n' roll...
