has anyone got an FX1 (pref in Europe?)
 
does anyone have any advise about linking an FX1 with an SF2 and a power amp and another 'composite amp' (ie power & preamp in one 2U box)? want to set-up a 'multi-rig'... hard to explain!

I do exactly this. An F2B into an SF2 into a Lexicon G2 into a Euphonic Audio iAmp 800. Works fine. In fact, better than fine, it sounds awesome! With my Series I I preamp each pickup with the F2B and it allows the perfect tonal tweaking.
