Currently I'm using my guitar through a Ubisoft Rocksmith adapter, and I'm thinking of buying an expression pedal with a 6.3 mm jack output, but I don't know how could I connect it to my PC so I could use it in i.e. Amplitube.
Is the only solution to this is buying a relatively big and expensive USB interface?
I want to use only this pedal. Is there a single adapter on the market?
What other solutions are there?
