This might get asked a lot but I find it difficult to search for an up-to-date answer and one that does not suggest using a laptop or something like a pod with digital amp modeling.
Basically I want to mix a backing track coming from a laptop or mp3 player with the signal coming from my amp into headphones. I want to retain the ability to use my existing setup with my pedals and I prefer not use a digital amp.
For headphones I plan of buying a beyerdynamic dt 770 pro 80 ohm. My amp has an out for headphones but I need a way to mix in songs that I want to play along to while wearing headphones.
What is an easy way to achieve this? I have looked at some options like a scarlett focusrite but I have no idea if this will actually help me achieve what I want.
Cheers.
