Alans guitar preamplifier for soundcard based effects

This is a guitar preamp which we have not tested properly however the really neat thing here is how Alan utilised an old cardboard component box (which he turned inside out) as a serviceable enclosure. I think this is a great idea as really in this example the enclosure forms "a durable outer casing to prevent fallapart" (classic Simpsons reference) and cardboard suffices well here.
