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?

  • You need something that turns analog expression pedal voltages into a digital signal that a computer can interpret. One of the most popular and easiest ways to do that is to get some kind of MIDI controller that has an expression pedal input. Sep 16, 2019 at 20:07
  • @ToddWilcox could you recommend one which just has that one input?

  • I've found this beatbars.com/en/home.html , but it's a bit expensive for me.

    This isn’t a site for product recommendations. Even if it were, I don’t know of much in the way of midi controllers for less than €50. You might look at a music instrument retailer web site and see what they have. Sep 16, 2019 at 21:26

USB instrument interfaces don't have to be large and expensive, there are small and inexpensive versions available.

If you want to use a standard effects pedal like a WAH then a simple USB interface will work.

The Behringer interface line starts at around $30 USD. You would send the guitar into the expression pedal, then into the interface.

If you want to control the software to use built-in expression, then you need to use a MIDI controller. There are a few different configurations available, but the most direct for what you describe would be an "Expression pedal to MIDI adapter" which starts around 50 Euro.

I have seen stand-alone MIDI expression pedals on the market before, but I believe the price range starts around $150 USD and goes up from there.
