I put my twin reverb inside a cardboard box in the garage, and then put the mic I used to mic it in a tin can, and put the tin can inside the box, then recorded it into a one track cassette tape player, but ran the audio output from that into a four track and then fed that back into Ableton with some plate reverb.

It sounded like Whole Lotta Love.

Is that the kind of thing you guys are talking about???
