Thanks hurghanico.
I'm not totally sure how the hex pickups work, so I'm not sure if I would be losing something in quality by going via an analogue cable into a low-end USB audio interface, compared to the all digital route into a POD HD500 and then into my PC.
At 500 Euro for the POD, there would need to be a noticeable quality difference to justify that over a 70 Euro Behringer USB interface.
Could anybody offer an opinion as to whether you can really tell the difference (or if there are any other advantages) to going the all digital route?
