snare envy so here's my 13 year old one.

Here's my old snare bought in Los Angeles whilst on holiday. It's tiny, known as the biscuit tin.

It doesnt get much use as I'm not a drummer. I did a local festival with my old band and there was a shared kit but bring your own snare and cymbals. The departing drummer laughed at it when he saw it and stopped when he heard it. Amzing sounding piece of kit in the right hands (not mine).

Love it.

What size?

My guess is 12 by 6 inches.
