Robb,

That's weird. I also have Guitar Rig LE (the version that was on the cover DVD of Computer Music back in 2008 or 2009)

What has been your experience using ASIO drivers with the Saffire? I borrowed one that has the speaker emulation built in (Saffire Pro 24 DSP) and the mix control software was insanely complicated. So complicated that I never got it to work properly - that is, I couldn't get my mic or guitar signals in and be able to monitor through plugins. I was basically going to be allowed to keep it indefinitely. I gave it the college try for about 3 evenings - when I wanted to be doing some recording. I took it back to work and went back to my PreSonus Firebox. Then my recording lappy (Thinkpad Z61m) gave up the ghost and I gave up on firewire interfaces.

Bought a Tascam US-800 (several threads here about those dodgy drivers), but I have figured out a way to get that interface to behave most of the time - turns out is has a memory leak - so you have to save often, kill the driver, re-instantiate the driver and then carry on. Kind of a hassle, but at least it works.

Back to your thing - have you ever used an instrument level input into the Saffire? It sounds like it since you've used it with Sonar. What was the magic there?

Believe it or not with ASIO4ALL drivers, you can get really low latency out of most on-board sound cards, but you won't have the right kind of impedance matching to get good level and drive from the guitar.

Sorry if I've misled you...Trying to help you save a buck and a back

I will admit the Fender G-DEC 30 that my father-in-law bought this past January on clearance at Guitar Center was very tempting. I think he paid $220 for it. Now, that's a modeling amplifier with ability to play along with .mp3 files you load onto SD cards, can re-program the amp modeller (we converted his into the blues version of the G-DEC), headphone outlet for silent practicing, works as a recording interface, etc. I should have bought the other one that they had in stock.
