I recorded my first albums on analogue tape, "Obsession" and the second Vision album "Till the End of Time" were done on ADAT's, around 1999 I bought a Pro Tools 24 plus system, but lately I have been working mostly with Logic Audio which I prefer. When it comes to recording I am a Mac freak. Windows is cool for office use but not for serious music stuff if you ask me. Things were definitely not better in the old day. Tape machines needed lots of maintenance, ADAT's had lots of problems with the tape and the machines were far from perfect. With Pro Tools or Logic Audio things do go wrong too, I lost two weeks of work once when my computer crashed. I had to redo all the bass parts of "Condition Red" plus some other stuff. That was NOT funny. What did I learn? Always Back-up!
 

For years I was been using a German built Tube rack setup by Kitty Hawk when I retired my dusty Marshall's.  I also have a 4 x 12" Cabinet of the same brand (used to have 2 cabinets) but I must confess though that that for "War", "Earthbound" and  "Dreamchild "I had mostly been using the Line 6 POD XT quite a lot too as it's very convenient to get the exactly same sound twice.

For "Tango" I used a Peavey 6505+, a Fender Twin and a Fender Bassman and lots of people seem to have noticed the difference.
 

Yes, I do a little bit of this too. My sound of preference is the original Hammond B3 which I don't have but I recently got a Korg B3 clone, which I am quite happy with. For analogue sounds I prefer my Nord Lead, but recently I have mostly been working with soft synths, mostly the stock ones that comes with Logic Audio.
