I have a Spider IV75 without any interfaces or other Line 6 products. I see the custom tone section and wonder what one would need in order to send a custom tone to the amp. I also noticed products such as the POD, Sonic Port, Pedal Boards, etc. All I really want to do is find a tone and upload it to the amp to get the sound.
Is there a specific interface I need?
Can a USB interface be built?
Thanks for any help.
