I'm actually looking at running 3 amps now. I'm going to look into an 18 watt Marshall clone to run with a VOX 1x15 speaker, and try to find a Roland JC-77 to run my dirt pedals into.
'Tis a fantastic idea. I run my Vox AC30 slightly dirty with my T-Rex (until I get hold of a Maxon OD820), my JC-77 clean, and in a move inspired by Sloppy_Phil, am splitting into my Orange Crush. Unfortunately, where I'm using my Boss DD-3 and CE-5 to split the signal, there's a fair deal of tone loss.
Still, this rig is sexy. Are you going to continue using it, even since you got your Eleven rack?
