He said he use it in Error Operator by Taking Back Sunday

I have a Marshall cabinet with the original Greenbacks [speakers] in it. I also play a [Gibson] SG Special through that. But I feel that the cabinet is a good 75% of my sound. It's an old, original, warm-sounding, fuzzy cabinet, and I've never heard one that beat it. You could plug mostly anything into it, and it [would] just sound beautiful and from another time. So that would be the piece I couldn't part with.
