Ran through a little bit of "My Girl" each time. Here is the amp order for each run-through.
1) Streamliner 900, flat, post-EQ
2) Streamliner 900, pre-EQ
3) Mesa M9 Carbine, pre-EQ
4) GBE 1200, pre EQ
Thanks for the clips.
After a quick listen, the post-EQ SL clip is the easiest to pick out. Sounds very nice, IMO. All the pre-EQ clips were fairly similar, at least upon a quick comparison. If it were me, I'd probably use the post-EQ send on the SL.
