Recording solution ideas

CHrisP86

So in a couple of weeks I want to test out various combinations of speakers in my speaker cab.

I was thinking it would be nice to try and record the combinations, and would be nicer if I could actually just re-amp guitar tracks to play through the amp/speakers so I can just listen and maybe mess with the amp eq.

So, what's the cheapest re-amping solution (I don't even have an audio interface at the moment).  This is really just a whim so I don't want to spend loads.

Or, I'm wondering whether to just knock the recording idea on the head and use a loop pedal to keep the sound going while I mess with the eq.  I don't have a loop pedal either so might need a recommendation on one of those as well...

Thanks
