From my Musicman equipped with Variax
Variax output > Line6XPS box > Zoom 504II (I DO love this unit)> P.A. I use variax only for acoustic/dobro/banjo/12strings/sitar sims...
Di Marzio jack output > Morley ABY > one output goes to the planet waves tuner / the other ouput goes to the pedalracks true bypass looper in which loop I put the Crybaby switchless > 11R > straight to the P.A
I use a Ernie Ball VPJR6180 as expression pedal and a French homemade Midifootcontroller X-digit Bybuzz Technologies.
I can use the 2 outputs (variax and Di Marzio) at the same time, I think only my variax transplant guitar allows this...
Enjoy
Cheers
