wat? It would not require any special input. All you need is your standard 1/4'' guitar cable (which I assume you have) and a 1/4'' (female) to 1/8'' (male) adapter, then you can plug it right into your mic or line in port. They are like $3 at radio shack, but I don't know if you have radioshack in the UK. You should be able to find them at any similar electronics store.
I personally use FL for this, and you can get various free VST effects online. I recommend Shred from acme bar gig. Shred is basically a preamp and cabinet modeller, and it's pretty decent.
