I just realised my 802 is at least 8 years old. It's had many hours of use as my "in-the-house" ampless rig.
It's been very dependable, but only just recently the Main Volume pot has developed a bit of scratchiness. I'll pull it bits one of these days and give the whole thing a good clean. It's pretty dusty and has never really been covered in its entire life.
Mark, can't you go direct into the interface with the Katana? Or are you mixing/splitting multiple channels into the Focusrite then into your computer?
